小弟目前有台主機
裡面有一張16PORT的SATA磁碟陣列卡
目前是裝有6科WD 1.5TB的硬碟再做 RAID5
今天一早發現的問題是裡面的一號硬碟掛了
所以必須盡快再買一顆硬碟
以棉再掛一顆資料就都毀了
現在的考慮點為"使否應該直接買個兩TB的裝上去??"
因為價錢實在是差異太小了
所以目前心中的疑問為
當我換成另外一顆2TB的硬碟時
RAID卡一定只把它當成是1.5TB的使用對吧??
那麼如果我慢慢換
到最後都把硬碟換成是2TB的
那麼我可以使用磁碟擴充的功能把這磁碟陣列改成六顆2TB的硬碟做 RAID5嗎??
還是因為他一開始就只是六顆1.5TB的磁碟陣列
所以無法擴充成為2TB的磁碟陣列??
希望大大可以理解我上述所說明的意思
謝謝
