サムスンが、現行840 シリーズの後継となる新型 SSD 「840 EVO」 シリーズを発表しました。

サムスンのコンシューマー向けSSD にはエントリーの840シリーズと上位の 840 Pro シリーズがありますが、新製品の 840 EVO はエントリーモデルながら最大容量1TB、最大書き込み速度 520MB/秒を誇ります。
変更点としては、まず製造プロセスが 20nm クラスから 10nm クラスの 3bit MLCへと微細化。コントローラーも現行の MDX から、より速いMEX へと進化しています。またSLCモードのバッファを使い書き込み速度を高速化する新技術 TurboWrite も導入しました。

その結果、250GB モデルではシーケンシャルライトが現行の 240MB/s から 520MB/s へ2倍以上高速化。また新たに加わった 1TB モデルのシーケンシャルリード / ライトは 540MB/s と 520MB/s 、ランダムリード / ライトは 9万8000 IOPS と 9万 IOPS に達しています。

(TurboWrite はMLC NANDフラッシュメモリの一部領域を高速なSLCモードで書き込みバッファとして使い、ドライブがアイドルになったら通常領域へ転送する技術。原理的にはバッファが溢れるほど連続して書き込めば速度は低下するはずですが、バッファは1TBモデルで12GB分(3bit MLCで36GB分) と比較的大容量が確保されており、通常の利用ではここに収まるとされています。技術的詳細は参考リンク先へ。)

容量は新たに 750GB と 1TB が加わり、120GB/250GB/500GB/750GB/1TB の5種類。

主な仕様は本体サイズ 2.5インチ、接続方式は SATA 6Gbps。一般的に製造プロセスの微細化は製品寿命を縮めると言われていますが、保証期間は変わらず3年間。

世界の主要なマーケットでの発売は8月上旬を予定。価格は今のところ発表されていません。

追記: 米国価格が発表されました。

120GBが109.99ドル、250GBが189.99ドル、500GBが369.99ドル、750GBが529.99ドル、1TBが649.99ドル。

Samsung Unveils New Solid State Drives at its Annual SSD Global Summit


New High-speed 1TB SSD to expedite transition to SSDs


SEOUL, Korea – July 18, 2013 – Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today held the 2013 Samsung SSD Global Summit at the Westin Chosun Seoul in celebration of the launch of its new solid state drive (SSD), the Samsung SSD 840 EVO. Along with the announcement of its latest SSD and under the theme of "SSDs for everyone," the Samsung SSD Global Summit also explored the future of the global SSD market, which is quickly replacing the hard disc drive (HDD) market.


"After accelerating the growth of the SSD market with last year's launch of entry-level, high-performance SSDs, we are introducing much faster SSDs with up to 1TB capacities offering consumers a wider range of choices," said Young-Hyun Jun, executive vice president, memory sales & marketing, Samsung Electronics. "Samsung continues to enhance its SSD brand image by delivering the industry's highest quality solutions and continuously increasing its SSD market share by expanding the adoption of higher density SSDs especially in client PC segments."


At this year's event, Samsung unveiled new high-performance, high-density SSDs. Among the highlights were the 840 EVO, a consumer-oriented entry-level, high-performance SATA based SSD offering up to 1TB capacity.


As part of its strategy to expand into the consumer market and further popularize SSDs, Samsung plans to initially introduce the Samsung SSD 840 EVO to major global markets in early August. Samsung will expand into additional markets at a later date.


The new Samsung SSD 840 EVO line-up makes use of the industry's most compact 10-nanometer class** 128Gb high-performance NAND flash memory, which Samsung began mass producing in April. With these chips and Samsung's proprietary multi-core MEX controller, the Samsung SSD 840 EVO achieves unrivaled value for performance with improved sequential read and write speeds.


At this year's Samsung SSD Global Summit, approximately 150 global business press, consumer media and power bloggers from twelve countries were invited, allowing Samsung to introduce high efficiency SSDs to global consumers and show participants just how simple it is to install and utilize SSDs in their notebooks.


Samsung has released the entry-level SSD '840 EVO' line-up with significantly higher sequential write performance. Utilizing the industry's most compact 10nm-class 128Gb high-performance NAND, Samsung proprietary controller and Turbo Write drive, the Samsung SSD 840 EVO boasts superior performance.


Compared with the 250GB 840 Series SSD, the highest selling capacity of the 840 lineup, the new 250GB 840 EVO now delivers 520MB/s sequential write speed – making it more than two times faster than the previous generation. In the case of 120GB model, the 840 EVO achieves up to 410MB/s sequential write speed, which is approximately three times as fast as that of the 120GB 840 Series SSD.


For the 1TB 840 EVO SSD, the sequential read/write performance has reached 540MB/s and 520MB/s. Furthermore, both the random read and write performance have improved, reaching 98,000 IOPS (Input Output Operations Per Second) and 90,000 IOPS, respectively. This significantly enhances the user's real-world computing experience, especially when he or she is dealing with very large data files.


The Samsung SSD 840 EVO line-up is available in five capacities: 120GB, 250GB, 500GB, 750GB, and 1TB, supporting a wide range of computing environments and IT applications. It has also significantly narrowed the capacity-induced differences in performance, which gives consumers a broader spectrum ofdevices to choose from.
