SSD
Seoul, Korea on Jan 03, 2007
Seoul, Korea - January 3, 2007 : Samsung Electronics Co., Ltd., the world leader in advanced semiconductor technology solutions, announced that it is now sampling its 16-gigabit (Gb) NAND flash memory with customers - the first NAND flash using 50 nanometer (nm) process technology.

The first samples of this high density NAND flash memory have a multi-level cell (MLC) design with a 4Kbyte (KB) page size to enhance both its read and write features. The new 4KB page function improves the conventional 2KB paging system for MLC NAND flash to double the read speed, while increasing write performance 150%.

By nearly doubling the overall performance of Samsung‘s MLC NAND, mobile consumers will enjoy faster data transfer speeds when storing or reading large data files whether they‘re using an external memory card, or a handset with a built-in flash solution such as Samsung‘s moviNAND?.

Early market introduction of 16Gb and higher density NAND flash memories is expected to accelerate the adoption of non-volatile memory applications such as flash-based solid state disks.

Samsung plans to begin mass producing its 16Gb NAND flash memory in the first quarter of 2007.
 

SAMSUNG Mass Producing Industry‘s First 1.8-inch, 64GB Solid State Drive, Targeted for Notebook PCs

Seoul, Korea on Jun 25, 2007
Seoul, Korea - June 25, 2007 : SAMSUNG Electronics Co., Ltd., the world leader in advanced semiconductor technology, announced that it has begun mass producing 1.8-inch solid state drives (SSD) at 64GB (gigabytes) - the highest density SSD available today for mobile computing applications.

"We see sharply increasing interest in SSDs among OEMs worldwide amid a growing push to launch premium SSD-based notebooks, particularly in the ultra-mobile category," said Jim Elliott, director, flash marketing, SAMSUNG Semiconductor, Inc.

SSDs feature far greater reliability, faster boot times and faster application start-up times than hard disk drives. SSD can also improve battery life by up to 20 percent in notebooks.

The 64GB SSD consists of 64 eight Gigabit (Gb) single-level cell flash memory chips. Use of 51nm process technology permits fabrication of much smaller components, with each chip having circuitry 1/2500th the width of a human hair.

SAMSUNG is aggressively expanding market development efforts for its SSDs. Industry wide attention on ultra-light, ultra-slim notebook PCs with flash memory based SSDs reflects early market support for this new storage medium. In addition, SAMSUNG has already introduced 32GB SSDs into ultra-mobile personal computers (UMPCs). SSDs also are being considered for server applications such as in advertising and for Web search engines. Other digital consumer products such as camcorders, PDAs and printers can now be equipped with SSDs ranging from 4GB to 64GB.

SAMSUNG‘s mass production of 64GB SSDs makes it the largest producer of high-capacity SSDs in the world.

Rapid expansion of the 1.8-inch SSD market will spark demand for even smaller SSD formats to be used in mobile consumer electronics. The miniaturization of SSDs will give rise to new types of digital products. Over the next three years, 2.5-inch and 3.5-inch SSDs will also gain a great deal of momentum for widespread use in standard notebooks and desktop PCs, respectively.

SAMSUNG expects that sales of SSD units will increase at a rapid 270 percent pace industry-wide between now and 2010 to become the largest growth segment in the NAND flash industry.
 

Samsung Introduces 1.8" - Type 64GB Flash-based Solid State Drive

on Mar 27, 2007 on Mar 27, 2007
Taipei, Taiwan - March 27, 2007 : Samsung Electronics Co., Ltd., the leader in advanced semiconductor technology, announced at its annual Mobile Solution Forum in Taipei that it has developed a 1.8”-type 64 Gigabyte (GB) flash-solid state drive (SSD). The new flash-SSD is based on an eight gigabit (Gb) single-level-cell (SLC) NAND, which provides significantly higher performance over conventional SSDs. The read and write performance of the new SLC flash-SSD have been increased by 20 percent and 60 percent respectively over the 32GB flash-SSD Samsung introduced last year, meaning that the new SSD‘s ability to outperform conventional rotating-media hard drives is even greater than had been anticipated. Samsung‘s continued nano-technology migration is a key enabling factor in the continued market segmentation for storage media. Besides the use of the 64 GB flash-SSD for notebook PCs, 8~16GB flash-SSDs will become viable solutions for use in personal navigation systems and digital camcorders, as will and hundred GB-level flash-SSDs for use in the server market. The flash-SSD, a drop-in replacement for a hard disk drive, is a secure and reliable means of storing personal or work-related data. It uses instantly-accessible, non-moving NAND flash memory instead of the noisier, power-hungry, jarring-sensitive rotating disc found in conventional hard drives, allowing it to upload and download data quickly and quietly with minimal power consumption. Samsung plans to start mass production of the 1.8"-type 64GB flash-SSD in the second quarter of this year. The SSD market is expected to reach US$200 million in 2007 and increases to US$6.8 billion by 2010 - an impressive compound annual growth rate of over 200 percent. 1.8"-type flash-SSD / rotating-disc HDD Feature Comparison Samsung‘s 64GB Flash-SSD Samsung‘s 32GB Flash-SSD 80GB HDD Read/Write Speed R : 64MB/s (4.3) W : 45MB/s (6.4) R : 53MB/s (3.5) W : 30MB/s (4.3) R : 15MB/s (1) W : 7MB/s (1) Weight 15g (1/4) 15g (1/4) 61g (1) Power Consumption O : 0.5W (1/3) I : 0.1W (1/15) O : 0.5W (1/3) I : 0.1W (1/15) O : 1.5 W (1) I : 1.5W (1) Note : 1.

Samsung Launches NAND Flash-based Solid State Disk for Mobile PCs

on Mar 21, 2006
Taipei, Taiwan - March 21, 2006 : Samsung Electronics Co., Ltd., the leader in advanced semiconductor technology, announced at the Mobile Solution Forum that it has begun offering a 32-Gigabyte (GB) NAND flash-based solid state disk (SSD) -- marking the first time that NAND flash has moved into mobile computing applications.

The 32GB Flash-SSD, which serves the same purpose as a hard disk drive, is a sophisticated data storage medium for notebooks and other mobile computers. It uses instantly-accessible, non-moving NAND flash memory instead of the rotating discs found in hard drives; therefore can upload and download data quickly and quietly with minimal power consumption.

The Flash-SSD weighs only half as much as a comparably-sized hard drive, but reads data three times faster and writes data 1.5 times faster. The SSD uses just five percent of the electricity needed to power a hard disc drive and is noiseless. Its design is free of any motor or other mechanical parts.

The commercialization of Samsung‘‘s 32GB Flash-SSD is a historic milestone for storage devices as it marks the initial entry of NAND flash memory in the mass mobile PC market.

Samsung sees the overall global SSD market surging from US$540 million in 2006 to US$4.5 billion by 2010.

Samsung Flash Solid State Drives (SSDs) Fully Compatible with Windows

on Oct 17, 2006
Seoul, Korea - October 17, 2006 : Samsung Electronics Co., Ltd., leader in advanced semiconductor technology, today announced that its three solid state disk (SSD) drives have been officially recognized by Microsoft Corporation as fully qualified Windows-compatible peripherals.

After thorough testing by its Windows Hardware Qualification Lab (WHQL), Microsoft has validated that Samsung SSDs meet all of the requirements for storage media in a Windows operating environment.

"Microsoft‘‘s certification of Samsung‘‘s SSDs provides designers with the added assurance of full compatibility in a demanding Windows environment, with our SSDs adding a strong dose of speed, reliability and power savings." said Jon Kang, senior vice president of Technical Marketing at Samsung Semiconductor.

Samsung‘‘s SSDs also markedly enhance system performance. The SSDs have a data read speed of 57MB/s and data write speed of 32MB/s, more than double the performance levels of a 1.8-inch HDD. Moreover, the SSDs provide a performance boost of up to 50 times that of a 1.8 HDD when servicing small, random data "read" requests. Such faster speeds shorten application program operating time as well as system boot time.

Samsung‘‘s new solid state memory solutions also enable longer battery life. Their power usage rate in an operational mode is less than 0.5W and in sleep mode just 40mW, which extends battery usage up to 30 minutes.

With no moving parts, Samsung‘‘s SSDs provide higher reliability with greater resistance against vibration, shock, extreme temperature, noise and heat emission.

Microsoft has certified a 32GB 1.8-inch sized Samsung SSD, a 32GB slim-type Samsung SSD (53.6x70.6x3.0mm) and a 16GB small-type SSD (56x48x3.8mm). The new sizes support the physical requirements of sub-notebook PCs.

The SSDs‘‘ substantial size and weight advantages are expected to further encourage a steady adoption of SSDs into a number of PC applications, such as in ultra mobile PCs, "ruggedized" notebooks and special industrial applications.

Seagate to industry: HDDs will continue to dominate storage

 

While NAND flash memory storage in the form of SSDs is being touted as the next killer application, manufacturers of HDDs (and some companies manufacture both) are not sitting in the park position. David Burks, director of product line management, consumer electronics, Seagate Technology, reminded the DISKCON 2007 audience that HDDs are still the storage technology of choice. He cited Gartner data showing that in 2006 <1.5% of all memory storage was in flash, but the forecast percentage only goes up to <5% by 2011 [see chart below].

The title of Burks‘ presentation, "Hard Drives and Flash Memory: The Virtuous Circle of Storage Technologies," drove home his main point. While much of the demand for flash memory storage is coming from consumer demand -- i.e., most content consumers want to retain on their personal devices (MP3 players, USB drives, digital cameras, etc.) -- this content is often originally stored on tethered PCs containing HDDs. And much of the content people want to download from Web sites is stored on enterprise servers or the server farms of sites such as Google, Yahoo, and YouTube, and these server farms are using HDDs for storage. Even content that is downloaded to flash memory devices, he noted, is often saved on backup systems that contain HDDs.

So as far as Seagate is concerned, the more flash memory devices that are sold, the greater will be the demand for HDDs, and HDDs will continue to dominate the storage industry. -- -- D.V. 

Samsung makes an enterprise play with SSDs

Date: ??, 2007

By Debra Vogler, Senior Technical Editor, Solid State Technology

The growing role that solid-state drives (SSDs), which use NAND flash memory to store digital data, are playing in the storage market was the subject of much discussion at last week‘s IDEMA DISKCON 2007 conference in Santa Clara, CA.

Jim Elliott, director of flash marketing at Samsung, was upbeat about the growing market for new applications using NAND flash memory, explaining that the NAND market is diversifying beyond consumer applications, such as USB drives, MP3 players, and the cell phone, to SSDs. He noted that the cost of NAND flash is decreasing ~50%/GB/year, while density is increasing at a rate of 2X/yr. The typical density range for an MP3 player as well as cell phones is ~512MB?8GB; for SSDs, the range is 32GB?64GB.

Samsung expects several additional key growth areas for NAND flash: DSC/DSLR, DVC, and car navigation/GPS systems. Presenting market data from the SEC, Elliott anticipates a >14X GB increase between 2007 and 2010 for the navigation market, with the number of units surging from slightly less than 30M in 2006 (portable and built-in units combined) to >100M units by 2010.

As NAND storage densities continue to increase, Samsung sees a major opportunity in the notebook space -- projecting that 71% of capacity requirements in corporate notebooks are <60GB, according to Elliott. But the "play" is not just in the market itself ? rather, a chance to get past the seasonal cyclicality (i.e., year-end holidays) imposed by the proliferation of applications in consumer electronics at the lower density levels. Because SSD densities have now reached the level required for corporate notebooks (64GB), Samsung believes the time is ripe to pick this low-hanging fruit.

Key to selling into corporate IT customers, Samsung believes, will be SSD attributes of reliability, high-impact resistance, light weight, and overall performance (e.g., sequential read/write speeds) and low power consumption. However, there‘s evidence that the pitch is working for more than just the corporate notebook customer -- the company recently announced that its 2.5" SATA 64GB SSDs are available in Dell and Alienware consumer notebooks. Dell is offering Samsung‘s SSD drive on its XPS M1330 ultra-portable notebook, with plans to make it available across additional XPS systems and its Latitude corporate notebooks and Precision mobile workstations later this year. Alienware is going to provide a 128GB SSD configuration, using dual 64GB SSD drives in a RAID 0 array, in addition to a single 64GB SSD combined with a large capacity 200GB 7200RPM drive for the Area-51 m9750 gaming notebook.

The next adjacent market Samsung is targeting is the sophisticated gamers -- but these gamers aren‘t "kids," Elliott noted, pointing out that the average gamer is 31 years old and typically buys 2-3 PCs a year to take advantage of newer faster processors or memory types. "These are people very in tune with performance, so an SSD is another arrow in the quiver to have the fastest PC on the block," he said. The size of the gaming market segment belies the fact that this demographic is at the leading edge of the technology adoption curve, Elliott added. "The gamers are the thought leaders, these are the guys who blog [and] post performance metrics; they see which way the industry is going."

Once SSD densities get above 100GB, Samsung‘s next target market is the mass consumer, for which it plans to offer 128GB SSD densities by the end of 2008. After that, the company expects SSD densities to continue to increase, but it is also researching the possibility of combining single- and multi-level cell (SLC and MLC) technology to drive down cost and get further leverage in the consumer electronics space. SSDs currently use only SLC technology for higher performance and better endurance, Elliott explained, but because MLC has a much smaller die size/GB it‘s possible to get anywhere from 70%-90% more GB/wafer (depending on lithography and yields) ? and even with MLC‘s lower yield, it is an attractive proposition for driving down cost in consumer electronics storage devices.

Although work is still in the R&D stage, the company hopes to be the first to offer the SLC-MLC combination. "We‘re very well positioned," Elliott told WaferNEWS. "We have ~90% market share on SLC flash, so we expect to leverage off our SLC portfolio, and we‘re the world‘s largest MLC supplier as well." -- D.V.
 
 

Samsung Introduces Server-Grade NAND flash for SSDs

Samsung Electronics announced today that it collaborated with Sun Microsystems to develop a SLC NAND flash memory with five times the endurance of conventional NAND flash memory. This would put the "ultra-endurance server-grade" flash memory at 500k program/erase cycles.

To extend the endurance, Samsung likely tweaked the underlying cell process and/or modified the programming algorithm. The net result is that the improved endurance comes at the expense of reduced performance or retention. However, by targeting high transactional enterprise applications with this device, the degraded retention should not be an issue.
 

Toshiba Eyes 50% Share of Notebook SSD Market in 2010

May 9, 2008 19:52
Shinichi Kato, Nikkei Microdevices

Atsutoshi Nishida, president and CEO of Toshiba Corp, expressed the company‘s commitment to solid state drive (SSD) with multi-level NAND flash memory at the corporate strategy meeting for fiscal 2008 in Tokyo on May 8, 2008.

"We aim to win at least a 50% market share for SSDs used in notebook PCs in 2010 or 2011," Nishida said.

The company expects that SSD-equipped machines account for 10% of all notebook computers in 2010, and 25% in 2011.

For the development of SSD technology, Toshiba organized a company-wide project team, feeling that it would be too difficult for Toshiba Semiconductor Co to be able to handle the multi-level NAND flash memory by itself. Members of the project were brought together not only from Toshiba Semiconductor but also from Toshiba‘s personal computer and HDD departments, in addition to the heads of R&D for the entire company.

"I asked the related sections of the HDD business that might compete against SSD technology for their support and gained it," Nishida said. "I told them that unless they provided their expertise and complete cooperation, the company would not make any further investment in HDD technology."

Nishida emphasized that not many competitors can keep up with Toshiba in the development of multi-level NAND flash memory because it is an extremely difficult technology. This is why Toshiba aims to win at least a 50% market share for SSD used in notebook PCs, he said.

固態(tài)存儲盤(pán)(SSD)的發(fā)展之快將超出預料

 
 硬盤(pán)(HDD)不僅在個(gè)人消費電子設備領(lǐng)域基本被NAND閃存/卡擠兌得幾乎無(wú)容身之地,如今,在它占據主導的PC/服務(wù)器數據存儲領(lǐng)域,也開(kāi)始受到后者的巨大威脅。NAND閃存在功耗、速度、數據可靠性、重量以及靜音等方面具有非常明顯的優(yōu)勢,隨著(zhù)輕薄型筆記本電腦在整個(gè)PC市場(chǎng)份額的持續增加,NAND的這些優(yōu)勢變得更加具有吸引力,基于NAND閃存的固態(tài)存儲盤(pán)(SSD)正在逐步走入這些應用。

“由于價(jià)格還太昂貴(上千美元),目前我們的SSD主要面向出口,國外一些個(gè)人筆記本用戶(hù)和服務(wù)器用戶(hù)對此有一定需求。雖然短時(shí)間內容它還不可能取代已達T級容量的硬盤(pán),但發(fā)展勢頭不錯,市場(chǎng)前景很好?!北就罶SD制造商憶正存儲技術(shù)(深圳)有限公司資深工程師黃河指出。

的確,SSD正不斷朝更高容量密度/耐用性和更低價(jià)格演進(jìn),促使它在整個(gè)存儲器市場(chǎng)的份額逐年增加。如圖1所示,Gartner預計2012年將發(fā)展成44億美元的市場(chǎng)規模(有人稱(chēng)這一預測過(guò)于保守,實(shí)際發(fā)展速度將更快),而這一切得益于NAND閃存技術(shù)的進(jìn)步以及巨頭公司們的推動(dòng)。


圖1:未來(lái)幾年SSD與HDD設備的市場(chǎng)預測(來(lái)源:Gartner)。

<>< b=""> <>

很多讀者一定已經(jīng)了解到,就在6月初,當存儲器巨頭三星公司剛剛宣布推出42nm閃存芯片不久,英特爾與美光就宣布其閃存合資公司IM Flash Technologies已開(kāi)發(fā)出34納米的32Gb的多層單元(MLC)和16Gb單層單元(SLC)芯片,使得每GB的成本價(jià)降低到1美元以下,將三星、東芝、Hynix等其他巨頭拋在身后(領(lǐng)先半年左右,見(jiàn)圖2)。


圖2:NAND閃存巨頭之間工藝競賽曲線(xiàn)。

英特爾在工藝技術(shù)方面領(lǐng)先性常常讓人“嘆為觀(guān)止”,如今在閃存工藝開(kāi)發(fā)上得到了充分發(fā)揮。美光存儲器系統開(kāi)發(fā)部副總裁Dean Klein不久前在世界巡回發(fā)布會(huì )上展示了一個(gè)用于新一代34納米器件生產(chǎn)的300毫米晶圓(圖3),指出其上可切割出400個(gè)左右的32Gb芯片,相當于每片晶圓包“產(chǎn)出”1.6TB的NAND閃存容量。而IM Flash Technologies已在研發(fā)20nm工藝級別的64Gb MCL閃存器件,預計將于2009年問(wèn)市,不過(guò)Klein沒(méi)透露具體細節。


圖3:用于新一代34納米NAND器件生產(chǎn)的300毫米晶圓,可切割出400個(gè)左右的32Gb芯片。

不僅在工藝上有重大突破,此新器件也標志著(zhù)標準NAND向高速NAND的轉變,其讀寫(xiě)的速度有5-6倍的提升,極大地提高了存儲器帶寬,特別適用于SSD、USB3.0、超高速緩存盤(pán)、視頻點(diǎn)播服務(wù)器、混合硬盤(pán)驅動(dòng)器等應用,而對于其他一些關(guān)鍵特性亦有顯著(zhù)改進(jìn)(如表1),另外,器件接口標準支持實(shí)現了從ONFI1.0向ONFI2.0的轉變(備注:ONFI是Open NAND Flash Interface的縮寫(xiě),它是由英特爾發(fā)起的一個(gè)標準聯(lián)盟,旨在統一行業(yè)中所有NAND器件、NAND模組、主機控制器以及驅動(dòng)軟件之間的接口,不過(guò)東芝和三星并不買(mǎi)帳,沒(méi)有加入該聯(lián)盟,而是另起爐灶,共同制造基于東芝開(kāi)發(fā)的另一種接口標準LBA的NAND閃存產(chǎn)品,也得到了不少下游廠(chǎng)商的支持。)

芯片供應商積極介入SSD成品供應

美光NAND市場(chǎng)開(kāi)發(fā)總監Kevin Kilbuck透露,他們共有三個(gè)300毫米晶圓廠(chǎng),位于美國Viegina州的工廠(chǎng)已達到100%產(chǎn)能,位于Utah州的另一個(gè)工廠(chǎng)在未來(lái)幾個(gè)月也將達到100%產(chǎn)能,而在新加坡新建的工廠(chǎng)將在本月竣工,2009年會(huì )增加產(chǎn)能。據悉,英特爾與美光將平分以上所有產(chǎn)能,但各自獨立進(jìn)行產(chǎn)品推廣和銷(xiāo)售。兩大公司的強勢進(jìn)攻無(wú)疑將在NAND應用市場(chǎng)有所斬獲,對此其他巨頭決不可能坐視不管,業(yè)內人士都認為,更加激烈的技術(shù)和產(chǎn)能競賽將會(huì )在下半年上演。

被視為NAND新機遇的SSD市場(chǎng)自然也會(huì )被波及,不過(guò)這種影響是積極的,因為將加速SSD價(jià)格的下降,推動(dòng)它的普及。業(yè)內普遍預計SSD價(jià)格每年下降速度為40-45%。而另一個(gè)催化劑就是,除了提供新一代高速閃存芯片給SSD制造商,數得上名的NAND閃存芯片巨頭們都在推出自己的SSD產(chǎn)品。以美光為例,目前他們面向筆記本和臺式PC市場(chǎng)的1.8和2.5英寸SATA接口SSD產(chǎn)品C200最高容量已達到256GB(基于34納米閃存器件),基于MLC NAND,連續讀取速度為200MB/s,連續寫(xiě)速度為120MB/s。面向對性能要求更高的服務(wù)器、工業(yè)和網(wǎng)絡(luò )應用設備市場(chǎng),美光也推出了基于SLC NAND的2.5英寸SATA SSD產(chǎn)品 P200,連續讀取速度達到250MB/s,連續寫(xiě)速度達到250MB/s。據Kilbuck介紹,SLC型產(chǎn)品的耐用年限為10年,MLC型產(chǎn)品能達到5年左右,當然這與主控制器的配合使用也有很大關(guān)系。


圖5:美光的NAND產(chǎn)品組合簡(jiǎn)圖(注:控制器是搭配其它公司的產(chǎn)品)。

美光沒(méi)有透露他們采用了哪家公司的主控制器,有業(yè)內人士猜測,可能是采用了英特爾的嵌入式控制器,專(zhuān)門(mén)針對SSD應用進(jìn)行了優(yōu)化,可以節省SATA橋芯片。憶正存儲技術(shù)(深圳)有限公司資深工程師黃河則表示,為滿(mǎn)足設計需要,他們也使用了自己設計的主控制器。

筆者認為,存儲器芯片廠(chǎng)商介入SSD成品的供應將會(huì )對純粹的SSD制造商產(chǎn)生一定沖擊,不過(guò)由于該市場(chǎng)方興未艾,對每個(gè)人來(lái)說(shuō)機會(huì )將大于挑戰。

滿(mǎn)足日益增長(cháng)“戶(hù)外”存儲需求,英特爾將為超級便攜式PC提供嵌入固態(tài)硬盤(pán)

英特爾公司即將為其超級便攜式PC平臺嵌入SSD(固態(tài)硬盤(pán)),旨在滿(mǎn)足用戶(hù)日益增長(cháng)的“戶(hù)外”存儲需求。Z-P140 PATA固態(tài)硬盤(pán)將作為一種可選式模塊向OEM廠(chǎng)商供給,供它們嵌入在面向Menlow平臺的主板上。

Menlow平臺面向超級便攜式PC,它還包括Silverthorne處理器和Poulsbo芯片組。據英特爾公司的產(chǎn)品經(jīng)理拉爾森在上周五招開(kāi)的一次會(huì )議上表示,基于Menlow平臺的產(chǎn)品將在2008年的上半年上市銷(xiāo)售。

這種微型SSD芯片只有0.6克的重量,其容量分別為2GB和4GB。據拉爾森表示,通過(guò)將四個(gè)這樣的SSD芯片連接到一個(gè)標準的PATA接口,主板上的存儲容量可以擴展到16GB。然而,由于沒(méi)有機械部件,SSD的能耗低于傳統硬盤(pán),因此,它們更適用于便攜式設備中。據英特爾公司的營(yíng)銷(xiāo)經(jīng)理特洛伊表示,Z-P140 PATA的存儲容量在兩年后將達到64GB。

除此之外,英特爾公司還表示,它計劃在明年1月份舉行的消費電子產(chǎn)品展會(huì )(CES)上展示由華碩、明基、聯(lián)想等廠(chǎng)商生產(chǎn)的基于Menlow平臺的超級便攜PC。并于2009年推出Moorestown━━新的超級便攜式PC平臺。

 
 
 

固態(tài)硬盤(pán)市場(chǎng)爆發(fā),Jedec將制定行業(yè)標準

 主要為DRAM接口制定標準的Jedec組織最近新成立了一個(gè)標準小組,為采用NAND閃存芯片的固態(tài)硬盤(pán)制定標準。JC-64.8委員會(huì )將制定用于嵌入式或可移動(dòng)存儲設備的固態(tài)硬盤(pán)標準,以推動(dòng)現有存儲設備的發(fā)展。

該標準小組由Seagate公司的Alvin Cox和Micron的Scott Graham聯(lián)合擔任主席,于5月份舉行了首次會(huì )議。在2007年8月召開(kāi)探討會(huì )和對業(yè)內公司進(jìn)行一次調查之后,Jedec聯(lián)盟決定成立這個(gè)標準小組。

據Jedec最近發(fā)表聲明,委員會(huì )將定義“接口標準中所沒(méi)有包含的推動(dòng)現有接口標準(命令協(xié)議和電氣接口)的新參數、機械互連、工作環(huán)境、電氣特性、可靠性測試方法和操作步驟。這個(gè)新的標準小組旨在和相關(guān)的Jedec委員會(huì )以及其它定義大容量存儲標準的協(xié)會(huì )(包括串行ATA國際組織,USB3.0協(xié)會(huì )和其它組織)協(xié)同工作。

與此同時(shí),另有兩個(gè)由Intel主導的小組正在著(zhù)手開(kāi)發(fā)用于滿(mǎn)足閃存硬盤(pán)要求的閃存芯片和閃存控制器接口標準。非易失性存儲主機控制器接口工作組(NVMHCI)于2008年4月宣布此計劃,而開(kāi)放NAND閃存接口小組(ONFI)早在2006年5月就有此計劃。

Jedec組織目前仍在吸收會(huì )員。Jedec董事會(huì )主席Mian Quddus在一份聲明中表示,“業(yè)界需要集思廣益來(lái)制定固態(tài)硬盤(pán)標準,用于使全球市場(chǎng)盡快接受具有最佳性能的SSD產(chǎn)品,使消費者的利益最大化?!?

此前不久,Samsung和Sun Microsystems發(fā)表了一份聯(lián)合聲明稱(chēng)已合作開(kāi)發(fā)一項針對計算機服務(wù)器用閃存驅動(dòng)的8G單層單元(SLC)新設計。據這兩家公司稱(chēng),他們將NAND閃存芯片的讀/寫(xiě)周期提高了五倍。另外,新興公司Fusion IO和惠普目前正合作開(kāi)發(fā)閃存控制器。

據International Data Corp預測,到2012年固態(tài)硬盤(pán)產(chǎn)量將達到2.2百萬(wàn),市場(chǎng)銷(xiāo)售額將達到900,000,000美元。目前固態(tài)硬盤(pán)的市場(chǎng)銷(xiāo)售額為260,000,000美元。

圖表:全球硬盤(pán)出貨量預測(百萬(wàn)個(gè))
來(lái)源:IDC

  1. 來(lái)自IDC、iSupply 和Trendfocus 等機構的統計數據表明,06 年全球硬盤(pán)出貨量在4.3 億個(gè)左右,同比增長(cháng)12.9%,2010 年前仍可保持10%以上的CAGR。我們根據多方數據,自己模擬的預測結果(如上)也大致相同。因此我們仍對未來(lái)幾年內硬盤(pán)市場(chǎng)持較為樂(lè )觀(guān)態(tài)度。
  2. 而從上圖我們可看出,硬盤(pán)的增長(cháng)主要來(lái)自于筆記本電腦和消費電子產(chǎn)品的快速增長(cháng)。而對于各類(lèi)產(chǎn)品增長(cháng)的動(dòng)力,我們推測如下:
    1. 臺式機:1)Vista 07 年的推出,將刺激消費者提高硬件配置而加快更新速度;2)亞洲、非洲的市場(chǎng)空間還較大,在中國“電腦走進(jìn)農村”07 年起力度也明顯加大。
    2. 筆記本:替代臺式機速度不減,且價(jià)格下降進(jìn)一步擴大了潛在消費群體。
    3. 消費電子:配備1”以下微硬盤(pán)的手機、DV、PDA 等開(kāi)始進(jìn)入快速上升通道,DVR、機頂盒、視頻監控的流行則拉動(dòng)了3.5”大硬盤(pán)的快速增長(cháng)。雖然我們預計09 年后,移動(dòng)便攜設備中的1”以下微硬盤(pán)將逐漸被SSD(固態(tài)硬盤(pán))替代,但整體消費電子硬盤(pán)快速增長(cháng)仍將保持一段時(shí)間。
    4. 企業(yè)應用:在全球向以視頻、圖片等為代表的數字媒體2.0 時(shí)代過(guò)渡中,海量數據存儲、災備以及高速檢索成為普遍現象(我們可看到Youtube 這樣的視頻網(wǎng)站越來(lái)越多),因此我們保守估計,未來(lái)也可保持5%-7%的穩定增長(cháng)。
硬盤(pán)下游各產(chǎn)品未來(lái)增長(cháng)動(dòng)力如下。
1、臺式機:Vista + 亞非空間還很大
2、筆記本:替代臺式機增速不減
3、消費電子:便攜式設備和DRV、機頂盒等媒體設備正處于快速上升通道
4、企業(yè)應用:向數字媒體2.0 時(shí)代的過(guò)渡導致對視頻、圖片等數據存儲需求的大增

SSD(固態(tài)硬盤(pán))短期難撼硬盤(pán)主流地位

  1. 我們的觀(guān)點(diǎn)是:4年內我們的觀(guān)點(diǎn)是:4 年內 SSD 難撼硬盤(pán)主流地位。主要是SSD 價(jià)格短期內還無(wú)法被大多數消費者接受。業(yè)內主流觀(guān)點(diǎn)是1)到2010 年,32GB 以下的微硬盤(pán)可能會(huì )被SSD 取代;2)硬盤(pán)和SSD 會(huì )共存相當長(cháng)的時(shí)間:硬盤(pán)向大容量數據存儲方向發(fā)展,SSD 主要用在移動(dòng)便攜式設備中。
  2. Dell、Samsung、Sony 都在今年推出了SSD 筆記本,其中Sony 在07 年8 月發(fā)布了一款配備32GB SSD 的筆記本,售價(jià)2099 美元,所附帶的32GB SSD 價(jià)格在480 美元左右。目前主流筆記本硬盤(pán)都在80GB 以上,我們用下圖預測了配備64GB SSD 筆記本未來(lái)的價(jià)格走勢(考慮到屆時(shí)廠(chǎng)家可能因SSD 價(jià)格貴而縮小了容量,以降低整個(gè)筆記本的價(jià)格)。假設其他部件價(jià)格不變。

  2. 我們看好硬盤(pán)制造外包細分領(lǐng)域的未來(lái)增長(cháng)。從硬盤(pán)產(chǎn)業(yè)鏈來(lái)看,我們認為利潤率最低的HSA(磁頭堆裝配)業(yè)務(wù),是未來(lái)外包發(fā)展最快的環(huán)節。就出貨量而言,目前硬盤(pán)廠(chǎng)商56.2%的HSA 業(yè)務(wù)自產(chǎn),43.8%的業(yè)務(wù)外包給TDK、長(cháng)城開(kāi)發(fā)和ALPS。而今年3 月,ALPS 已與TDK 簽訂協(xié)議將磁頭業(yè)務(wù)賣(mài)給TDK。之后獨立廠(chǎng)商就僅TDK 和長(cháng)城開(kāi)發(fā)兩家。我們預計HSA 外包比例將在2011 年達到56.8%(根據最新預測,與前期報告比我們稍作調整,下同)。進(jìn)一步我們認為,在HSA 獨立廠(chǎng)商市場(chǎng)份額不斷提高的趨勢下,HSA 企業(yè)相對硬盤(pán)廠(chǎng)商的議價(jià)能力也將逐漸提高。

HAS業(yè)務(wù)外包因素在于:
1)降低成本,并將資源投入到較高利潤的硬盤(pán)其他環(huán)節中。
2)建立后備生產(chǎn)線(xiàn),降低僅自身單一生產(chǎn)的風(fēng)險。

News Analysis




Event

On 14 January 2008, EMC announced it will integrate flash-based solid state drives (SSDs) into its core product portfolio, the EMC Symmetrix DMX-4 storage system. Preliminary performance claims for the DMX flash drives are a tenfold improvement in response times and a thirtyfold improvement in maximum input/output rates relative to physical disk drives of equivalent capacity. EMC plans to offer flash drives in 73GB and 146GB capacities later in 1Q08. Prices were not released.




Analysis

SSDs deliver order-of-magnitude performance improvements, enhanced reliability and lower power consumption than contemporary physical disk drives. SSDs do this by eliminating the mechanical delays associated with traditional spinning disks; delivering more bandwidth and mitigating write penalties by leveraging algorithms that optimize parallel activity.

The two primary barriers to broad market acceptance of SSDs are cost and the ongoing performance improvements of RAID storage systems. Whether DMX flash drives — nominally priced at 30 times the cost of a physical disk of equivalent capacity — will surmount these barriers to become a market success remains uncertain. Flash drives are the first SSD option offered in a general-purpose, high-end storage system, but the modest success of earlier SSD systems and drive options suggests that flash drives may be a niche product. Balanced against this concern is the possibility that the lower cost of flash drives in absolute dollars, on a dollar-per-GB basis, may allow them to become a mainstream success.

The use of nonvolatile flash memory instead of dynamic random access memory (DRAM) eliminates the need for battery backup but raises concern about flash drive service lives. The flash drive design addresses this concern by using enterprise-class single-level cell (SLC) NAND flash components and advanced flash management techniques in the drive, resulting in longer mean times between failures (MTBFs) and improved mean times between data loss (MTBDLs) than RAID sets built using physical disks.






Recommendations



  • Users with applications bottlenecking on performance: Consider installing flash drives where performance needs and capacity requirements make them an optimal solution.
  • All users: Require availability guarantees that are easily enforceable and include meaningful remedies until the market validates DMX flash drive technology.
 
 
 

SSD取代硬盤(pán)的模式


東芝半導體社長(cháng)齋藤升三演講中提到:2011年將會(huì )有1/4的筆記本電腦內建SSD。到底SSD有什么魔力,取代傳統的硬盤(pán),又SSD會(huì )以什么樣的姿態(tài)來(lái)取代硬盤(pán)呢


傳統式硬盤(pán)一向是計算機里一個(gè)為人詬病的零件,撇開(kāi)機械式老舊且不耐震之外,它的重量就足以讓筆記本電腦的整體重量壓不下來(lái),其他像是發(fā)出噪音、壽命短、數據傳輸速度慢等一連串的缺點(diǎn),不禁讓人問(wèn):這是電子時(shí)代該出現的產(chǎn)物嗎?

我們一直在找尋取代硬盤(pán)的大容量?jì)Υ嫜b置,但都尋尋覓覓,直到半導體制程的突破,連帶拉起的NAND FLASH儲存技術(shù)崛起。NAND Flash具備有電子式的儲存,完全沒(méi)有任何一個(gè)機械裝置,重量可以壓到硬盤(pán)的好幾十分之一,傳輸速度比硬盤(pán)來(lái)的快,耐震且體積小,在任何一點(diǎn)來(lái)看都是優(yōu)于硬盤(pán),唯其存取壽命有限,但在SLC(Single-Level-Cell)方面卻還是大有可為,十萬(wàn)次的存取次數以及比MLC(Multi-Level-Cell)快上三倍的速度,皆是取代硬盤(pán)的不二人選,足夠用于操作系統碟7年到10年以上。

混合硬盤(pán):傳統硬盤(pán) + SSD
目前,SSD受制于單價(jià)仍遠高于傳統式硬盤(pán),短期間很難能100%取代硬盤(pán)。但基于對SSD的需求,所以出現了混合硬盤(pán)的形式?;旌嫌脖P(pán)即一個(gè)SSD碟當作是操作系統碟,計算機的操作系統安裝在此碟中,在開(kāi)機關(guān)機、存取數據或是耐震上,皆有不錯的表現,而大量的數據則儲存在傳統的硬盤(pán)上,由于傳統硬盤(pán)有CP值上的優(yōu)勢,故可以做大容量的數據保存。另外,一般數據存取并不影響到震動(dòng)中操作系統的正常運作,因為作業(yè)統是放在SSD碟里面的。這樣的組合同時(shí)可達到極佳的效能,也達到降低成本。依照現在市面的價(jià)錢(qián)來(lái)看,16G SLC SSD搭配160G/250G的傳統硬盤(pán)是比較劃算的組合。

混合硬盤(pán):SLC SSD + MLC SSD
前面提到SLC制程的SSD會(huì )比MLC SSD價(jià)錢(qián)來(lái)的高,原因在于SLC的制程難度較高,但其one-by-one bit傳輸的特性,讓他的傳輸速率比MLC制程的NAND FLASH快上三倍,壽命是MLC制程的10倍,而耗電量又略小于MLC制程的優(yōu)勢(SLC NAND FLASH約略減少15%的耗能),讓SLC SSD成為追求快速與穩定的操作系統槽的不二首選。但是在非系統程序數據存取方面,由于數據極少搬動(dòng)且不追求高速的情況下,可以采用單價(jià)較低的MLC制程的SSD當作數據存放的區域。目前市面上暢銷(xiāo)的ASUS Eee PC即是采用此一策略,缺點(diǎn)是MLC制程的SSD價(jià)錢(qián)仍舊高于一般的傳統硬盤(pán)。

SSD應用范圍
目前SLC SSD的大容量?jì)Υ娣桨?,主要用于航天或是軍事用途,作為高速用途的裝置上面,單價(jià)雖高但具備速度快壽命又長(cháng)且耐震的特性,適用于航天工業(yè)或是軍事用途等比較在意效能且環(huán)境較惡劣的情況下使用。而小容量的SLC SSD儲存方案,目前主要應用在筆記本電腦的系統磁盤(pán)上,由于小容量SLC SSD單價(jià)比高容量的低,但容量足以應付系統磁盤(pán)的需求。

MLC制程的儲存方案應用范圍就比較廣了。舉凡市面上目前大多數的NAND FLASH的應用如MP3、隨身碟、手機、照相機、記憶卡或是其他小零件的應用,幾乎都是以MLC NAND FLASH為主,原因無(wú)他,就是因為MLC的價(jià)錢(qián)低,而這些裝置的運作是不需要高速的需求的。但是MLC的壽命也是一大障礙,尤其是對于隨身碟這一類(lèi)型的裝置,常需要放置重要文件,所以風(fēng)險不小。

而混合型的硬盤(pán)應用范圍大多用于筆記本電腦及追求效能的桌面計算機。因為筆記本電腦對于耐震的要求十分貼近SSD的需求,再考慮價(jià)格的因素下,SSD加上傳統硬盤(pán)或是SLC SSDMLC SSD是一個(gè)很好的解決方案;而在計算機的應用方面,可以參考筆記本電腦的方案或是另一個(gè)由Intel提出的概念-Turbo Memory。Turbo Memory即在計算機主機里面加裝一個(gè)小容量的SSD,在關(guān)機的時(shí)候將RAM里面所執行的數據加載到SSD里面,下次開(kāi)機的時(shí)候直接將SSD里面的信息加載RAM里面,節省了許多開(kāi)關(guān)機的時(shí)間。

結論
對于SSD的最大的關(guān)鍵還是在于價(jià)錢(qián),但人類(lèi)目前追求半導體制程的演進(jìn)以及其他算法的改良,SSD取代硬盤(pán)勢必是未來(lái)的趨勢了,就看看市場(chǎng)如何反應或是有什么新的應用推出。

惠普在服務(wù)器市場(chǎng)出貨量與營(yíng)收都成為第一名


根據研究機構Gartner調查顯示,2008年第一季全球服務(wù)器出貨量為227萬(wàn)臺,比起2007年第一季211萬(wàn)臺,年成長(cháng)率達7.6%。市值達136億美元,比起去年同期130億美元,年成長(cháng)率為4.3%。


惠普不僅在PC市場(chǎng)成為龍頭,在服務(wù)器市場(chǎng)也成為龍頭。根據Gartner研究顯示,2008年第一季惠普的服務(wù)器出貨量達68.3萬(wàn)臺,年成長(cháng)率為7.6%。更重要是惠普在服務(wù)器營(yíng)收上的年成長(cháng)率達10.3%,高于出貨量成長(cháng)率。 可見(jiàn)得其開(kāi)始往IBM長(cháng)期主導的高階服務(wù)器市場(chǎng)前進(jìn)。

2007
年時(shí)惠普在服務(wù)器營(yíng)收上仍舊落后于IBM,進(jìn)入2008年,由于惠普ProLiantIntegrity系列的服務(wù)器熱銷(xiāo),使得惠普第一季服務(wù)器營(yíng)收達到40億美元,超越IBM39億美元,市場(chǎng)占有率也向上增加了1.6個(gè)百分點(diǎn),達到29.6%。此外,惠普在Blade服務(wù)器市場(chǎng)的營(yíng)收也比去年同期成長(cháng)13%以上。

在營(yíng)收成長(cháng)率上,第二名的IBM,第三名的戴爾,第五名富士通/富士通西門(mén)子,年成長(cháng)率分別為2.1%,6.6%4.9%。只有第四名的升陽(yáng),呈現負成長(cháng)的情況。

惠普在2008年第一季服務(wù)器出貨量比去年同期成長(cháng)7.8%,在全球服務(wù)器市場(chǎng)占有率上突破30%,達到30.1%。

戴爾仍是全球第二大服務(wù)器出貨量廠(chǎng)商,2008年第一季出貨量達到51.6萬(wàn)臺,比起2007年第一季的44.6萬(wàn)臺,年成長(cháng)率達15.8%,是前五大廠(chǎng)商中成長(cháng)率最高的廠(chǎng)商,市場(chǎng)占有率也提高至22.7%。

從出貨量來(lái)看,IBM和升陽(yáng)的服務(wù)器年成長(cháng)率分別為2.3%6.6%。至于第五名的富士通/富士通西門(mén)子出貨量成長(cháng)率卻呈現下滑2.6%。(719字)

2008年第二季PC出貨量成長(cháng)率超乎預期


根據研究機構IDCGartner研究顯示,2008年第二季全球PC出貨量成長(cháng)率都超出預期的好,分別為15.3%16.0%。主要原因是新興市場(chǎng)需求強勁,以及歐美PC市場(chǎng)以降價(jià)刺激需求,年成長(cháng)率不僅高于第一季,且季成長(cháng)率也都是正數,呈現淡季不淡的情景。


Gartner原本預估第二季PC成長(cháng)率只有11.2%,可是根據其統計發(fā)現,成長(cháng)率竟然高達16%,令人吃驚。IDC也是得到相同的結論。

IDC
認為第二季PC出貨量會(huì )如此亮麗,主要原因包括:產(chǎn)品更新、在通路上廠(chǎng)商之間競爭加劇與平均銷(xiāo)售價(jià)格下滑所致?;旧蟻?lái)說(shuō),消費者面對財務(wù)壓力還能夠產(chǎn)生如此穩定的成長(cháng)率,可見(jiàn)得PC在生活上的角色愈來(lái)愈重要。原本Gartner預期美國PC市場(chǎng)出貨會(huì )衰退近2%,但實(shí)際上卻成長(cháng)4.2%。

在廠(chǎng)商表現方面,惠普除了在美國市場(chǎng)仍輸于戴爾之外,其他市場(chǎng)都位居第一名寶座。根據IDC研究,惠普以18.9%全球市場(chǎng)占有率居于領(lǐng)先地位。在美國卻與第一名的戴爾差距又拉大。

+
者之間市場(chǎng)占有率差距為6.6%,比起第一季差距6.4%,以及去年同期差距4.8%,又開(kāi)始逐漸拉大兩者之間差距。IDC認為戴爾在通路策略,尤其是擴充零售方式已經(jīng)生效。

無(wú)論GartnerIDC都認為,如果美國經(jīng)濟情況若因為油價(jià)與次級房貸又變的更糟,則年底惠普與戴爾之間的價(jià)格戰又在所難免。

第三名仍是宏碁的天下。不過(guò),根據Gartner數據顯示,蘋(píng)果2007年第二季在美國麥金塔銷(xiāo)售量攀高至139.7萬(wàn)臺,比起宏碁/捷威的133.1萬(wàn)臺,高了0.4%的市場(chǎng)占有率,因此宏碁何時(shí)整合捷威資源,并達到綜效是其保衛美國第三名寶座的關(guān)鍵點(diǎn)。(860字)

華碩Eee PC推出第二代,挑戰更多


2008年的Cebit展,一共有來(lái)自7個(gè)廠(chǎng)商展示8款低價(jià)迷你筆記本電腦,主要原因當然是華碩于2007年成功推出7Eee PC有關(guān)。此次,華碩也順勢推出下一代Eee PC,尺寸為8.9吋。


為了達到2008年出貨量500萬(wàn)臺的目標,華碩于2008年的Cebit展示了第二代Eee PC!

第二代Eee PC同樣是采用900MHz英特爾Celeron M處理器,屏幕尺寸為8.9吋,分辨率為1024 x 600。此外,華碩加大其固態(tài)硬盤(pán)至12GB,以及RAM1GB起跳。目前在未安裝Windows XP的情況下,預估售價(jià)為399歐元(約606美元)。如果安裝之后,將會(huì )高于此價(jià)格!

華碩認為,在已開(kāi)發(fā)國家中,年輕人、家庭主婦與年紀較大的人將成為第二代Eee PC的目標市場(chǎng)。

在第一代Eee PC時(shí),無(wú)論是開(kāi)發(fā)中國家或者是已開(kāi)發(fā)國家,都因為內建Linux操作系統的Eee PC,而造成風(fēng)潮。例如美國亞馬遜還曾經(jīng)幾周Eee PC系統產(chǎn)品銷(xiāo)售量排行在前十名之中,占據了5個(gè)名額。

當然Eee PC也激起了許多開(kāi)發(fā)中國家的PC廠(chǎng)商起而效尤。例如:印度的HCL廠(chǎng)商,就在2008年初,推出350美元且7吋屏幕的迷你PC,甚至在情人節時(shí)推出粉紅色版本。

同樣的本次Cebit展,有許多廠(chǎng)商加入展示的行列,包含Packard Bell(已被宏碁買(mǎi)下)、Medion、Gecube(精星科技)、Elonex、E-Lead(怡利電子)、Clevo(藍天計算機)與Amoi(夏新電子)。

其中,Packard Bell將在歐洲推出Dixon7吋迷你便攜計算機。其是采用1.2GHz威盛的C7微處理器,包含1GB RAM30GB的硬盤(pán),預估售價(jià)為599歐元!

由于宏碁與惠普都非常小心尋求在迷你便攜計算機中不與目前筆記本電腦產(chǎn)生銷(xiāo)售沖突,因此都會(huì )以不同態(tài)度進(jìn)入此市場(chǎng)。不過(guò),宏碁在歐洲擁有Packard Bell品牌,將能讓其放手一玩?。?span lang="EN-US">755字)

業(yè)界:SSD試水企業(yè)級存儲


從SSD依舊昂貴的價(jià)格、應用的限制等方面綜合評估,SSD在企業(yè)級存儲中的大規模應用還為時(shí)尚早。但是還真有很多人愿意頂著(zhù)高價(jià)偏偏選用它們的,這樣的用戶(hù),都是崇尚環(huán)保并且用于嘗試的。

  在IT消費產(chǎn)品領(lǐng)域,已經(jīng)有筆記本電腦廠(chǎng)商開(kāi)始選用SSD(固態(tài)硬盤(pán))來(lái)替代傳統硬盤(pán)。從2007年7月IBM宣布在刀片服務(wù)器中首次采用SSD,到2008年1月EMC在高端企業(yè)級存儲產(chǎn)品Symmetrix DMX-4采用SSD,再到2008年6月,Sun在服務(wù)器和存儲產(chǎn)品中也開(kāi)始支持SSD,SSD開(kāi)始登堂入室,從消費產(chǎn)品領(lǐng)域跨入到企業(yè)級應用中。但從SSD依舊昂貴的價(jià)格、應用的限制等方面綜合評估,SSD在企業(yè)級存儲中的大規模應用還為時(shí)尚早。

  優(yōu)缺點(diǎn)都很鮮明

  SSD最大的優(yōu)點(diǎn)就是速度快。SSD的速度至少比傳統硬盤(pán)快1個(gè)數量級(10倍)。這也決定了SSD的應用定位——需要快速處理海量信息的應用,比如電子交易系統、實(shí)時(shí)數據處理、主機交易處理等,其影響時(shí)間可達到毫秒級。EMC中國研發(fā)中心副總經(jīng)理、軟件總監李映舉例說(shuō):“某信用卡公司采用EMC基于SSD的Symmetrix DMX-4存儲系統,將過(guò)去處理欺詐探測信息的速度提高了6倍?!背怂俣瓤煲酝?,SSD的優(yōu)勢還體現在:SSD的內部沒(méi)有機械裝置,因而不會(huì )出現機械故障,而且噪音低、能耗少,其能耗只有傳統硬盤(pán)的1/5~1/6,符合綠色存儲的發(fā)展趨勢。

  在EMC之前,一些存儲廠(chǎng)商已經(jīng)把SSD應用于企業(yè)級存儲陣列中,比如CURTIS、Qbisys等。SSD突破了傳統硬盤(pán)的性能瓶頸,并且價(jià)格逐漸走低,因而SSD開(kāi)始從軍用系統、高性能計算等領(lǐng)域逐步拓展到商業(yè)和企業(yè)應用環(huán)境。

  但是,SSD的缺點(diǎn)也顯而易見(jiàn),最突出的就是價(jià)格高。不可否認,SSD的價(jià)格正呈逐年下降趨勢,但從目前的價(jià)格水平看,仍高出傳統硬盤(pán)數倍。一個(gè)1TB的傳統硬盤(pán)的價(jià)格約為550美元,而同樣容量的SSD的價(jià)格可能超過(guò)1萬(wàn)美元。Sun雖然表示將在今年底時(shí)推出較低價(jià)格的SSD,但也不否認,即便如此,SSD和傳統硬盤(pán)之間的價(jià)格差仍會(huì )十分明顯。

  兩種技術(shù)各取所需

  SSD根據采用的存儲介質(zhì)分為兩類(lèi):一類(lèi)采用Flash Memory存儲芯片,簡(jiǎn)稱(chēng)Flash SSD;另一類(lèi)則采用DRAM Memory存儲芯片,簡(jiǎn)稱(chēng)DRAM SSD。

  Flash SSD主要用于消費類(lèi)電子產(chǎn)品的存儲器(如MP3、MP4、數碼相機、手機等),也可用于移動(dòng)存儲(如U盤(pán)等)或工業(yè)標準尺寸的Flash SSD硬盤(pán)(如工控環(huán)境、軍用環(huán)境等)。Flash SSD具有優(yōu)異的讀性能,而且Flash Memory是非易失性的存儲介質(zhì),因此無(wú)需電源保護。Flash SSD的缺點(diǎn)在于寫(xiě)性能和耐久性較差。EMC Symmetrix DMX-4存儲系統采用的就是Flash SSD?!霸谄髽I(yè)級存儲中采用SSD,主要是為了解決存儲性能問(wèn)題。對于某些高端企業(yè)級客戶(hù)來(lái)說(shuō),即使再大的緩存也不能從根本上解決存儲性能的問(wèn)題,只有采用SSD取代傳統硬盤(pán),才能滿(mǎn)足對高存儲性能的需求?!盋URTIS公司莫樺介紹說(shuō),“SSD提供商STEC公司通過(guò)技術(shù)收購,使其大容量Zeus-IOPS Flash SSD的耐久性得到大幅度提升,并且在幾年后500GB的SSD的價(jià)格有可能降至2000美元。如果這一天真的到來(lái),那么當今的FC(光纖通道)磁盤(pán)就失去了存在的價(jià)值,傳統磁盤(pán)工業(yè)將被顛覆?!?/p>

  作為存儲領(lǐng)域的領(lǐng)先者,EMC必須提前對硬盤(pán)工業(yè)可能發(fā)生的巨變做好準備。李映表示:“EMC進(jìn)入SSD領(lǐng)域是一個(gè)慎重的決定,一方面是看到用戶(hù)有這方面的需求,另一方面也表明EMC對未來(lái)發(fā)展的判斷具有前瞻性?!?/p>

  DRAM SSD采用SDRAM或DDR SDRAM作為存儲介質(zhì),是易失性存儲,所以DRAM SSD需要一直有電源保持供電。一臺DRAM SSD設備內部除了I/O接口控制電路和DRAM Memory存儲芯片板外,一般還包含為DRAM Memory存儲芯片供電的鋰電池、糾錯電路,甚至還有在供電中斷時(shí)用來(lái)保護DRAM中數據的備份磁盤(pán)。DRAM SSD的優(yōu)點(diǎn)是讀寫(xiě)性能同樣優(yōu)異,而且具有高可靠性和耐用性。其缺點(diǎn)是需要始終保持電源供給,以保證數據不丟失。

  近年來(lái),Flash Memory存儲芯片的容量直線(xiàn)上升,而價(jià)格在直線(xiàn)下降。如果有一天,當Flash SSD的價(jià)格與同等容量的傳統硬盤(pán)相差無(wú)幾時(shí),Flash SSD有可能會(huì )全面取代傳統磁盤(pán)??梢赃@樣說(shuō),Flash SSD的市場(chǎng)目標是全面取代磁盤(pán)成為在線(xiàn)存儲介質(zhì),而DRAM SSD的市場(chǎng)目標則是滿(mǎn)足高端客戶(hù)對極高存儲性能的需求。

  可靠性有待證明

  SSD的性能及能耗優(yōu)勢,使得它在企業(yè)級存儲中的應用開(kāi)始受到重視。但目前只有EMC、Sun等少數廠(chǎng)商支持SSD,而SSD在普通商業(yè)領(lǐng)域中的應用才剛剛興起,還需要大量的實(shí)踐證明其可用性和可靠性。Iiluminata的咨詢(xún)師John Webster表示:“我并不認為人們采用SSD的速度會(huì )比其他存儲新技術(shù)更快。SSD供應商必須證明SSD是可靠的?!崩钣辰榻B說(shuō):“目前,EMC在SSD產(chǎn)品方面只有一家合作伙伴。經(jīng)過(guò)我們的反復測試,只有這家廠(chǎng)商的SSD產(chǎn)品在可靠性方面能夠滿(mǎn)足企業(yè)級存儲的需求?!?/div>
 
 
 
 
 

朗科發(fā)布國內首款SSD固態(tài)硬盤(pán)

日前,全球移動(dòng)存儲領(lǐng)導廠(chǎng)商朗科公司隆重發(fā)布了國內第一款采用閃存存儲介質(zhì)的SSD固態(tài)硬盤(pán)。

  日前,全球移動(dòng)存儲領(lǐng)導廠(chǎng)商朗科公司隆重發(fā)布了國內第一款采用閃存存儲介質(zhì)的SSD固態(tài)硬盤(pán),在業(yè)內引起廣泛關(guān)注?!癝SD固態(tài)硬盤(pán)的出現是存儲領(lǐng)域一個(gè)劃時(shí)代的技術(shù)革新。從此閃存為介質(zhì)的固態(tài)硬盤(pán)開(kāi)始了它替代傳統硬盤(pán)的偉大征程?!遍W存盤(pán)之父,朗科公司總裁鄧國順表示。

  朗科公司是國內移動(dòng)存儲廠(chǎng)商中第一個(gè)推出SSD固態(tài)硬盤(pán)的企業(yè),并一直是全球閃存應用的技術(shù)先驅。自1999年朗科公司發(fā)明全球第一款閃存盤(pán)以來(lái),先后在閃存應用及移動(dòng)存儲領(lǐng)域累計申請發(fā)明專(zhuān)利達兩百余項,覆蓋全球幾十個(gè)國家及地區,迄今已授權的發(fā)明專(zhuān)利達35件。

  SSD固態(tài)硬盤(pán)多項技術(shù)性能更加優(yōu)越

  相比傳統硬盤(pán),SSD固態(tài)硬盤(pán)擁有明顯的速度優(yōu)勢。據悉,朗科這款SSD固態(tài)硬盤(pán)讀取數據的速度達到了180MB/S,寫(xiě)入數據的速度達到了100MB/S,比傳統硬盤(pán)擁有數倍優(yōu)勢。搭載朗科SSD固態(tài)硬盤(pán)的筆記本從開(kāi)機到出現windows XP桌面一共只用了13秒,而搭載傳統硬盤(pán)的筆記本總共用了31秒,兩者差距超過(guò)一半。

  其次,SSD固態(tài)硬盤(pán)防震抗摔,數據存儲更安全。因為全部采用了閃存芯片作為存儲介質(zhì),所以SSD固態(tài)存儲器內部不存在任何機械部件,這樣即使在高速移動(dòng)甚至伴隨翻轉傾斜的情況下也不會(huì )影響到正常使用,而且在筆記本電腦發(fā)生意外掉落或與硬物碰撞時(shí)能夠將數據丟失的可能性降到最小。

  另外,SSD固態(tài)硬盤(pán)功耗小、噪音低、發(fā)熱量小。工作時(shí)靜音(固態(tài)存儲器因為沒(méi)有機械馬達和風(fēng)扇,工作時(shí)噪音值為0分貝),正因為沒(méi)有傳統硬盤(pán)磁頭與盤(pán)體之間的摩擦,因此它的發(fā)熱量小、散熱速度也快。

  朗科方面表示,在產(chǎn)品外形和尺寸上SSD完全可以做到與普通硬盤(pán)一致,包括2.5"、 1.8"等,甚至可以做得更小。SSD固態(tài)硬盤(pán)在重量方面更輕,與常規1.8英寸硬盤(pán)相比,重量輕20-30克,減少的重量有利于移動(dòng)設備的便攜性。朗科此次推出的SSD固態(tài)硬盤(pán)是2.5"產(chǎn)品,體積小巧,便于攜帶。

  SSD固態(tài)硬盤(pán)開(kāi)始步入商業(yè)應用

  SSD固態(tài)硬盤(pán)優(yōu)越的技術(shù)性能很快引起了各大電腦廠(chǎng)商及消費電子產(chǎn)品制造商的極大興趣。據悉,目前包括三星、英特爾、朗科等廠(chǎng)商都已經(jīng)發(fā)布了自己的固態(tài)硬盤(pán)。

  除了制造領(lǐng)域巨頭云集之外,SSD固態(tài)硬盤(pán)的商業(yè)應用也已經(jīng)邁開(kāi)步伐。例如2007年下半年,蘋(píng)果在MacBook Air中就以固態(tài)硬盤(pán)取代了傳統標準型硬盤(pán),華碩2007年推出的Eee PC,也采用了NAND Flash為儲存媒介的固態(tài)硬盤(pán)。

  “用戶(hù)也可以把它單獨當作一個(gè)系統盤(pán)來(lái)使用?!崩士品矫姹硎?,人們將可以重溫從386跳躍到奔騰3.0的感覺(jué)。

  不過(guò),有業(yè)內人士擔心,高昂的成本可能是固態(tài)硬盤(pán)迅速普及的攔路虎。與一個(gè)GB級別的容量相當的傳統硬盤(pán)產(chǎn)品相比,固態(tài)硬盤(pán)的價(jià)格要高出10倍左右。

  對此,朗科有關(guān)人士表示,閃存芯片的價(jià)格歷來(lái)呈現出指數下降的趨勢,2001年8M閃存盤(pán)價(jià)格是999元,今天8G的閃存盤(pán)也不過(guò)幾百元的價(jià)格。大容量SSD固態(tài)硬盤(pán)的成本未來(lái)兩年內將大幅度下降,全面普及只是時(shí)間問(wèn)題。      http://storage.chinabyte.com/446/8262446.shtml

Micron科技4號發(fā)表了高傳輸數據的下一代SSD“RealSSD P200”及“RealSSD C200”?,F已經(jīng)出現樣品,量產(chǎn)期預訂為2008年第四季度。

  Micron科技4號發(fā)表了高傳輸數據的下一代SSD“RealSSD P200”及“RealSSD C200”?,F已經(jīng)出現樣品,量產(chǎn)期預訂為2008年第四季度。

  

  RealSSD P200是適用于企業(yè)級的超高速SSD,采用SLC(Single Level Cell)技術(shù),實(shí)現了250MB/sec的讀寫(xiě)速度。接口為3Gbps傳送對應的SATA接口。

  消耗功率是0.3~2.5W,與傳統硬盤(pán)相比僅為十分之一;工作溫度為攝氏0~70度,比傳統硬盤(pán)有更廣范圍的運轉溫度。平均故障間隔為200萬(wàn)小時(shí),這一點(diǎn)在企業(yè)專(zhuān)門(mén)領(lǐng)域非常突出。
