最近又想添購硬碟了,不過去天價屋拉菜單看的時候就看到很多CMR/PMR的硬碟都只剩
5400RPM。雖然說7200和5400對硬碟的讀寫來說影響不太大就是
因為主要是找CMR/PMR硬碟,至於那些高容量擺明就是SMR的硬碟就先不討論了
而讓我不解的是東芝的DT01ACA300的3TB硬碟 Buffer只有64MB。(然後災情也不少)
但2TB還是保持128MB,DT01ACA200也改成DT01ABA200。轉速從7200RPM降到5400RPM
DT02ABA400的4TB硬碟雖然一樣是CMR/PMR,但看隔壁板測試說感覺比較像SMR(但型號上
是PMR/CMR,然後災情一樣也不少)
至於S和W兩家就不用說了,消費級的硬碟幾乎都朝SMR發展去了
感覺現在廠商都已經陸續朝SMR發展了,以後要挑1TB~4TB的CMR/PMR的硬碟只能找企業用
硬碟?
