SAMSUNG PM983 960GBのベンチマーク

SAMSUNGのエンタープライズ向けSSD、PM983シリーズの960GBモデルMZQLB960HAJR-00007がやってきた。宅内ネットワークの40GbE化により、サーバのストレージがSATAのSSDでは物足りなくなったため、うっかりポチってしまった。

速度的には最近のM.2なSSDの方が速かったりするんだけど、少しくらい遅くてもエンプラ向けの高信頼品が欲しかったのですよ。で、eBay見てたら販売店テスト済みの中古品が1万円弱だったので2台買っちゃった。PM963, PM953あたりなら同価格で新古品がそこそこ出回ってるようだが、中古とはいえPM983が1万円はなかなかのお買い得品。スペックは以下の通り。

  • シーケンシャル
    • Read 3000MB/s
    • Write 1050MB/s
  • ランダム
    • Read 400000 IOPS
    • Write 40000 IOPS
  • 1.3 DWPD (TBW=1366TB)
  • TLC (3bit MLC VNAND)

9/2に注文して受け取れたのは9/14。届いたモノは、綺麗な外観の書き込み量は1TB弱で、中古としては上々と言える。

搭載キャッシュ容量は不明。

Crystal Disk Markを何度か試した限り、テストサイズ1GiBの時は測定のブレも少なく安定した結果が得られるが、32GiBでは特に書き込み速度で測定結果のバラつきが見られた。恐らくキャッシュ溢れの影響だと思われる。ワーストケースでは4K1Tで60MB/sまで低下するのを確認している。

ちなみに、PCIe 2.0x4で接続した場合は↓こんな感じ。

当初、PCIe 2.0スロットに挿してたのに気付かず「Sequential Read: (960GB) Up to 3000 MB/sって書いてあったけどこんなもんか…」と思ったのは内緒。
