32QT1は速くなって良くわからん。240GBのSSDに対して93TB書き込んでるけど、問題になるような性能低下はなさそう。損耗率から計算すると残り280TBほど書き込めるようだ。 かたわれのSSDは結構深刻な状態で、ランダムライト速度が半分以下になってしまっている。

S.M.A.R.T.はメディア消耗指標は問題なさそうだが、電源断保護失敗で異常が検出されており、そのためか電源投入回数が跳ね上がっている。 電源断保護失敗でパフォーマンス低下ってのも良くわからんけど、内蔵の電源回路が不調→コントローラリセット→すぐ回復→辛うじて書き込みは継続、って感じなのかなー? 若干の不安はありつつも、別サーバでZFSのRAID-1構成で引き続き頑張ってもらう予定。
