インテルがメインストリーム向けの「第三世代SSD」こと Intel SSD 320 シリーズを発表しました。特徴は 25nm プロセス NAND Flash メモリの採用により最大容量が従来の160GBから一気に600GBに、価格も最大で30%ほど安くなったこと。またディスク全体のリアルタイム AES-128暗号化や書き込みアルゴリズムの改善など、セキュリティや信頼性の強化も施されています。
フォームファクタは2.5インチ、インターフェースは SATA 3Gbps。つまり命名規則こそ変わったものの、インテルのメインストリーム向け SSD として一時代を築いた X25-M シリーズの3代目 (" G3 ") にあたります。X25-Mは2008年夏の初代が50nm、2009年夏のG2が34nm。
容量は40GB ・80GB・120GB・160GBおよび300GB0・600GBが用意されます。速度はモデルにより異なるものの、インテルの公式ではシーケンシャルリードが最大270MB/s・ライトが最大220MB/s、ランダムアクセス性能はリードで39500 IOPS・ライトで23000 IOPS。IFがSATA 3Gbpsのメインストリームであることから、高速モデル Intel SSD 510シリーズ (6Gbps 接続時) ほどシーケンシャルの速度は出ていない一方、120GB以上のモデルでは、旧型 X25-M G2で差別化のためにあえて抑制してあるといわれた書き込み速度が解禁され大きく向上しています。
1000個ロット時の単価は40GBモデルが89ドル、80GB 159ドル、120GB 209ドル、160GB 289ドル、300GB529ドル、最大の600GBが1069ドル。インテルの発表文は続きへ、ベンチなどの詳細は参考リンクの Anand や PC Per などPC系サイトへどうぞ。Anand の分解では、コントローラは従来のX25-Mと同じチップが見つかっています (ただしSDRAMは省電力になり容量増加)。競争の激しい最近のSSD 市場では初代が登場したときほどのインパクトはないものの、インテル自慢の信頼性や容量・価格など、メインストリーム向けとして着実なアップデートです。流出ロードマップ のとおり昨年Q4に出荷されていればさらに存在感があったかもしれません。

Features Enhanced Performance/Reliability, Larger Capacities and 25nm Intel® NAND Flash Memory
* Third-generation Intel® SSD 320 Series on 25-nm NAND flash memory offers 40-, 80-, 120-, 160-GB plus higher capacity 300- and 600GB options.
* Advanced architecture enables robust, reliable SSDs with enhanced security features for desktop/notebook PCs or server data center storage.
* Performance, reliability upgrades enhance solid line of high-performing SSDs with up to $100 price drop over current Intel® X25-M SSD model.
SANTA CLARA, Calif.--(BUSINESS WIRE)--Intel Corporation announced today its highly anticipated third-generation solid-state drive (SSD) the Intel® Solid-State Drive 320 Series (Intel® SSD 320 Series). Based on its industry-leading 25-nanometer (nm) NAND flash memory, the Intel SSD 320 replaces and builds on its high-performing Intel® X25-M SATA SSD. Delivering more performance and uniquely architected reliability features, the new Intel SSD 320 offers new higher capacity models, while taking advantage of cost benefits from its 25nm process with an up to 30 percent price reduction over its current generation.
"Intel designed new quality and reliability features into our SSDs to take advantage of the latest 25nm silicon, so we could deliver cost advantages to our customers," said Pete Hazen, director of marketing for the Intel Non-Volatile Memory (NVM) Solutions Group. "Intel's third generation of SSDs adds enhanced data security features, power-loss management and innovative data redundancy features to once again advance SSD technology. Whether it's a consumer or corporate IT looking to upgrade from a hard disk drive, or an enterprise seeking to deploy SSDs in their data centers, the new Intel SSD 320 Series will continue to build on our reputation of high quality and dependability over the life of the SSD."
The Intel SSD 320 is the next generation of Intel's client product line for use on desktop and notebook PCs. It is targeted for mainstream consumers, corporate IT or PC enthusiasts who would like a substantial performance boost over conventional mechanical hard disk drives (HDDs). An SSD is more rugged, uses less power and reduces the HDD bottleneck to speed PC processes such as boot up and the opening of files and favorite applications. In fact, an upgrade from an HDD to an Intel SSD can give users one of the single-best performance boosts, providing an up to 66 percent gain in overall system responsiveness.1
The Intel SSD 320 Series comes in 40 gigabyte (GB), 80GB, 120GB, 160GB and new higher capacity 300GB and 600GB versions. It uses the 3 gigabit-per-second (3gbps) SATA II interface to support an SSD upgrade for the more than 1 billion SATA II PCs installed throughout the world. Continuing to offer high-performing random read and write speeds, which most affect a user's daily computing experience, the Intel SSD 320 produces up to 39,500 input/output operations per second (IOPS) random reads and 23,000 IOPS random writes on its highest-capacity drives. In addition, the company has more than doubled sequential write speeds from its second generation to 220 megabytes-per-second (MB/s) sequential writes and still maintains one of the highest read throughputs at up to 270 MB/s sequential reads. This greatly improves a user's multitasking capabilities. For example, a user can easily play background music or download a video, while working on a document with no perceivable slow down.
Already one of the most solid-performing SSDs over time, Intel continues to raise the bar on SSD reliability in the way it has architected its third generation, using proprietary firmware and controller, to further demonstrate that not all solid-state drives are created equal. In this rendition, Intel creatively uses spare area to deploy added redundancies that will help keep user data protected, even in the event of a power loss. It also includes 128-bit Advanced Encryption Standard capabilities on every drive, to help protect personal data in the event of theft or loss.
"Solid-state drives continue to be one of the hottest trends in computing," said Bernard Luthi, vice president of marketing, Web management and customer service at leading e-retailer Newegg.com. "Intel remains a top brand because of its consistent performance and extremely low return rate. We are sure customers will welcome the new higher capacity drives, and now is a great time for consumers to upgrade their PC to a fast new SSD."
Intel SSD 320 prices, based on 1,000-unit quantities, are as follows: 40GB at $89; 80GB at $159; 120GB at $209; 160GB at $289; 300GB at $529 and 600GB at $1,069. Check retailers/e-tailers for consumer pricing. All models include a limited 3-year warranty from Intel.
"With recent announcements, we have expanded our SSD product line and now offer both consumers and computer OEMs more SSD choices," said Tom Rampone, vice president and general manager, Intel NVM Solutions Group. "We see the Intel SSD 320 as a solid advancement to our SSD roadmap, and will continue to upgrade and refresh our SSD product line as we add more enterprise options for our business customers throughout the year."
Another benefit for Intel SSD purchasers is the Intel® SSD Toolbox with Intel® SSD Optimizer, a free utility which provides Microsoft Windows* users with a powerful set of management, information and diagnostic tools to help maintain the health and out-of-box performance of the drive. To help ease the installation process, all Intel SSD users can download the free Intel® Data Migration Software to help clone the entire content of a previous storage drive (SSD or HDD) to any Intel SSD.
Intel SSDs can be purchased in the United States from such retailers as Best Buy or Fry's Electronics, plus a variety of resellers, retailers or Internet e-tailers such as Newegg.com or Amazon.com worldwide.
