====== HGST HUH728080ALE604購入 ======
リファービッシュのHGST HUH728080ALE604が安く出てたので買ったった。初ヘリウム封入HDDなんだぜ。ちなみに、タイミング良いと米尼で199ドルで売ってる。直送してくれないけど。今回のは国内購入でござる。
例によって簡単にベンチ。これまた例によってUSB 3.0接続なので参考程度に。

15628053167セクタを13時間37分でゼロフィルしたので、平均転送速度は155MB/sということに。ゼロフィル中、並行で他の作業をしていた点を差し引いても[[blog:2017:2017-09-21|MD05ACA800]]よりは遅いと言えそう。
smartmontoolsによるS.M.A.R.T.は↓な感じ。室温26℃、HDDへフルアクセスしてる状態での値である。
