在落後HGST、WD及希捷差不多兩年之後
東芝終於推出第一款8TB硬碟了,上週末東芝旗下的X300高性能硬碟產品線增加了8TB容量
型號
此前的最高容量才6TB。東芝的8TB硬碟規格還不錯,7200RPM轉速,
28MB緩存,SATA 6Gbps介面。與前面三家公司不同,東芝在8TB型號上並沒有使用充氦技
術
使用的還是傳統PMR磁片,不過X300的價格可不算便宜。東芝X300系列硬碟主要針對專業
及遊戲PC等高性能市場
所以規格還不錯,不想WD、希捷那樣使用5400RPM或者5900RPM低轉速
上來就是7200RPM轉速,不過128MB緩存容量有點保守,其他家的大容量硬碟緩存多是
256MB。
此外,東芝實現8TB容量既沒有採用充氦技術,也沒有使用SMR磁記錄技術
用的還是傳統的PMR垂直磁記錄技術及TMR隧道磁阻磁頭。儘管官方並沒有公佈具體的規格
不過猜測跟HGST此前推出的Ultrastar He 8TB硬碟差不多,使用的應該都是SDK的第八代
PMR磁片,單碟1.5TB左右。
此外,東芝X300 8TB硬碟還支援NCQ、4K高級磁區等技術,典型功耗6W,最大功耗11.3W左
右。
東芝X300 8TB硬碟預計6月份上市,廠商建議價是359歐元,沒找到美元價格
按照慣例美元價格應該是359美元。以歐元價格來說,東芝8TB硬碟不算便宜
希捷的8TB桌面硬碟現在德亞價格已經低於300歐元,西數8TB紅盤是328歐元。
