奇怪 最近看了 SPCR 的 reivew,
aacs 好像從來沒有跑過高於 5400rpm 說



90Hz x 60 sec / min = 5400 rpm

許多 review 網站仍然認為 spindle speed 是固定的
只是 aacs 未來產品線保留用回 7200rpm的可能性

"IntelliPower term indicates that the GP family as a whole does not have a set spindle speed (nor a set buffer size, for that matter). Different capacity points may feature differing spin speeds and buffer sizes. For those that must know, WD admits "sub-6000 RPM operation" for the 1-TB Caviar GP"
