今回入手した中古 HDD も、前回と同じく Seagate Barracuda ES.2 1TB です。前回入手したものは S.M.A.R.T. エラーがある状態とのことで、かなり安い値段でしたが、今回の個体は、前回の値段＋600円程度で入手できました。
まず、S.M.A.R.T. の確認です。

このあと、４台構成の RAIDZ に組み込みましたが、resilver と scrub でエラーが出ませんでしたので、十分に使えそうな感触です。
2018-10-23追記
とうとう限界に達したようなので、６個目の中古HDD を購入して、zpool replace しました。まだ、OSから認識できていますので、廃棄する前に smartctl のデータを採取しました。
