インテルの新SSDが正式発表を迎えました。新モデルの型番は従来機種とおなじ X25-M。MLC NANDフラッシュを採用していること、シーケンシャルリード最大250MB/s・ライト最大70MB/sという数字もそのまま。変化したのはフラッシュメモリの製造プロセスが50nmから34nmにシュリンクされたこと。これにより、一年前のX-25M初登場時と比較して最大で約60% 安価になっています。(80GBモデル 1000個ロット時の単価が595ドルから225ドルへ)。
またシーケンシャルの数字こそ変わらないものの、インテル製 SSDの優位であるランダム読み書き性能はさらに向上しました。リードレイテンシは従来機種より約25%速い65μs。秒あたりのファイルの読み書き回数を示すIOPSでは4KB ライトが最大 6600 (80GBモデル)・8600 (160GBモデル)、リードが最大 35000など。
一方、事前のうわさにあった320GBモデルは少なくとも当初はラインナップされておらず、従来とおなじ80GB・160GBの2モデル構成です。国内での発売は7月22日本日より。1.8インチモデル X18-Mの34nm版は今四半期にも加わる予定。最大6割安くなったといっても旧機種デビュー時との比較であって、値下げを経た旧X-25 Mの市場価格からはほぼ据え置き・やや上乗せ程度に設定されている店が多いようです。

Intel Delivers Industry's First 34-Nanometer NAND Flash Solid-State Drives; Advancement Lowers Prices by Up to 60 Percent
SANTA CLARA, Calif.--(BUSINESS WIRE)--Intel Corporation is moving to a more advanced, 34- nanometer (nm) manufacturing process for its leading NAND flash-based Solid State Drive (SSD) products, which are an alternative to a computer's hard drive. The move to 34nm will help lower prices of the SSDs up to 60 percent for PC and laptop makers and consumers who buy them due to the reduced die size and advanced engineering design.
The multi-level cell (MLC) Intel® X25-M Mainstream SATA SSD is aimed at laptop and desktop PCs and available in 80 Gigabyte (GB) and 160GB versions. SSDs are data storage devices found inside computers. Because SSDs have no moving parts they offer faster performance and greater energy efficiency and durability than traditional hard disk drives (HDDs). A draw for gamers, media creators and technology enthusiasts, SSDs have also played a key role in the emergence of ultra-thin and light notebook PCs that are becoming increasingly popular due to their design, size and longer battery life.
"Our goal was to not only be first to achieve 34nm NAND flash memory lithography, but to do so with the same or better performance than our 50nm version," said Randy Wilhelm, Intel vice president and general manager, Intel NAND Solutions Group. "We made quite an impact with our breakthrough SSDs last year, and by delivering the same or even better performance with today's new products, our customers, both consumers and manufacturers, can now enjoy them at a fraction of the cost."
The Intel X25-M on 34nm flash memory is drop-in compatible with the current 50nm version and will continue to be drop-in compatible to replace existing hard disk drives (HDDs).
Compared to its previous 50nm version, the new Intel X25-M offers improved latency and faster random write Input/Output Operations Per Second (IOPS). Specifically, Intel's new SSD provides a 25 percent reduction in latency, for quicker access to data, operating at 65-microsecond latency compared to approximately 4,000 microseconds for an HDD.
Random write performance increases twofold, further separating the X25-M from other competing SSDs. By delivering up to 6,600 4KB write IOPS and up to 35,000 read IOPS, the X25-M continues to set the bar for SSDs, while leapfrogging HDDs which only operate at several hundred IOPS. This provides for markedly faster system and application responsiveness. These improvements in latency and IOPS not only benefit desktop and notebook users, but also server and workstation users, as they utilize Intel's cost-effective, yet performance-oriented, MLC SSDs for enterprise computing.
New channel prices for the X25-M 80GB are $225 for quantities up to 1,000 units (a 60 percent reduction from the original introduction price of $595 a year ago). The 160GB version is $440 (down from $945 at introduction) for quantities up to 1,000 units. The X25-M comes in a standard 2.5-inch form factor. The X18-M, in a 1.8-inch form factor, will begin shipping on 34nm later in the quarter.
Drop-in compatible with SATA-based HDDs and all operating systems, the X25-M will also support Microsoft Windows 7 when it becomes available. At that time, Intel plans to deliver a firmware update to allow support of the Windows 7 Trim command, along with an end user tool, to allow users to optimize the performance of their SSD on Windows XP and Vista operating systems.
