沒有效能測試, 反正效能一定很差啦
靜音表現耗電量表現不錯

不過有一段話很有趣.....
Our 750 GB sample is 5,400 RPM. Storage Review's 1 TB sample was 5,400 RPM. WD's literature lists the possible speed range as 5,400~7,200 RPM, but we have yet to hear reports of any models above 5,400 RPM.

意思是說WD官方說AACS可以自動調整5400~7200RPM
但目前卻沒有測試指出可以跑超過5400RPM
