SN640のファームウェア更新とかベンチマークとか こちらのページによれば、Western Digital Ultrastar DC SN640 U.2 NVMe SSDシリーズの初期ファームには、まれにSSDがタイムアウトし、機能不全を引き起こす可能性のあるバグがあるらしい。回復手段はSSDのフォーマットで、言わずもがなデータは失われることになる。あな恐ろし。 配布されている修正版ファームウェアはR1110021, R1410004で、手持ちのSN640はR1110012なので発生する可能性がありそう。というわけで更新してみる。 やり方は上記サイトに書いてある通り。Linux環境ならnvmeコマンドでSSDのFWをダウンロードし、適用し、マシンを再起動する。 nvme fw-download /dev/nvme0 --fw=FW.vpkg nvme fw-commit /dev/nvme0 -a 1 こんな感じでR1110021に更新されていることが分かる。 # nvme list | grep WUS4 /dev/nvme2n1 /dev/ng2n1 A06F8XYZ WUS4BB076D7P3E3 1 7.68 TB / 7.68 TB 4 KiB + 0 B R1110021 /dev/nvme1n1 /dev/ng1n1 A066EXYZ WUS4BB076D7P3E3 1 7.68 TB / 7.68 TB 4 KiB + 0 B R1110021 /dev/nvme0n1 /dev/ng0n1 A0647XYZ WUS4BB076D7P3E3 1 7.68 TB / 7.68 TB 4 KiB + 0 B R1110021 なお、このSN640たちは例によって中古で、いずれも2PB以上読み書きされている。データシート上の寿命は11210TBW(4kランダムライト時)であるから、S.M.A.R.T.が示すとおりまだまだ余裕がありそう。 CrystalDiskMarkとCrystalDiskInfoの結果は以下の通り。PCIeパススルーでVMで測定したものなので、値は参考程度に。
