WD 8TB HDDガチャで大勝利

WDの外付けハードディスクElements Desktopシリーズの8TBモデル(型番:WDBBKG0080HBK-JESN)の中身に、エンプラ向けのWD Goldの廉価版が入ってる事があるらしい聞いて購入したみたところ、見事に大当たりのHe10なWD80EMAZ-00WJTA0だった。やったね!

ハズレの方は非ヘリウムでWD80EMAZ-00M9AA0とのこと。まぁ、ハズレと言ってもこちらもUltrastarの流れを組む製品で、ただの8TB HDDとして見ても安い部類なので十分当たりと言えるんだけども。

製品ライン Ultrastar DC HC510? Ultrastar DC HC320?
ヘリウム ×

非ヘリウムのWD80EMAZ-00M9AA0の方が静かで低発熱という話もあり、一概に当たりハズレとは言えないかも。自分的にはHUH728080ALE604で既にヘリウム体験済みなので、WD80EMAZ-00WJTA0にそれほど強いこだわりはなかったりする。

電源として3.3Vが来てるとHDDが起動しないらしく、うちのSuperChassis 743TQ-1200B-SQのHDDベイで使えるか心配だったけど、余裕のよっちゃんで使えた。すなわち、SUPERMICROのバックプレーンCSE-SAS-743TQでは使えると考えて良さそう。

smartmontoolsでのS.M.A.R.T.は↓な感じ。なお、室温26℃、ディスクにフルアクセスしてる最中に取得したものである。
