NVMe SSD 摩耗度調査サマリー¶
基本的には全NVMeで同じなので、Deviceによらず Percentage Used を摩耗度として扱う。
ただし、Intelのように100%を超えることがあるとしているメーカーもある (参考) ので、ひとまず 100% 以下であることが確認できれば良い。
Percentage Used は各社が独自に計算しているが、SATA SSDのように中途半端に乱立したAttributeを見るよりは指標が一定なので良い。
以下の2点に留意していれば良いと思われる(もちろんエラー通知はこれとは別の話)
- Available Spare が 1% 以上であること
- Percentage Used が 100% 以下であること
