====== 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！ {{ :blog:2019:wd80emaz-00wjta0.jpg |}} 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。 ^ ^ WD80EMAZ-00WJTA0 ^ WD80EMAZ-00M9AA0 ^ ^ 製品ライン | Ultrastar DC HC510? | Ultrastar DC HC320? | ^ ヘリウム | 〇 | × | 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[[blog:2018:2018-01-18|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[[https://www.supermicro.com/en/products/chassis/4U/743/SC743TQ-1200B-SQ|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。 smartctl 7.0 2018-12-30 r4883 [FreeBSD 12.0-RELEASE-p4 amd64] (local build) Copyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: WDC HGST Ultrastar He10 Device Model: WDC WD80EMAZ-00WJTA0 Serial Number: 7HKJKU1N LU WWN Device Id: 5 000cca 257f1cf4c Firmware Version: 83.H0A83 User Capacity: 8,001,563,222,016 bytes [8.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5400 rpm Form Factor: 3.5 inches Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-2, ATA8-ACS T13/1699-D revision 4 SATA Version is: SATA 3.2, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Mon Jul 22 00:29:58 2019 JST SMART support is: Available - device has SMART capability.
