RAID空襲
RAID is a computer acronym meaning “Redundant Array of Independent Disks.” RAID是一個電腦的縮寫,意思是"獨立磁盤冗餘陣列" 。 Wikipedia維基百科 . 。 In this case we’re talking about “mirrored” disks, one of the simplest RAID configurations, where two identical disks contain identical data so that one can continue operating if the other fails.在這種情況下,我們談論的"鏡像" ,磁盤,其中一個最簡單的RAID配置,而兩個相同的磁盤包含相同的數據,因此你可以繼續經營,如果其他失敗。 Since they contain the same data the second disk doesn’t add any disk capacity, but it does add reliability.因為它們含有相同的數據,第二盤沒有添加任何磁盤容量,但它確實增加可靠性。 Pros:利弊:
- The hard disk is MUCH less apt to crash.硬盤要少得多,容易造成事故。 Only people who have experienced a crash can fully appreciate this.唯一的人,經歷了碰撞,可以充分理解這一點。
- Perhaps I can get away with less backup, eg only back up the most sensitive data.也許我可以蒙混過關少備份,例如只有回到了市場上最敏感的數據。
- Or, I can buy a THIRD drive and或者,我可以買一個三徑與 hot-swap熱插拔 it, so the swapped-out drive is the backup.它,所以對調出硬盤作後盾。
- I’d enjoy the experience of setting it up and using it.我會享受的經驗建立這個系統,並使用它。
Cons:兩種意見:
- It’s more expensive: I need two drives, not one, and the motherboard (which manages the drives) costs a little more.它的更昂貴:我需要兩個驅動器,而不是一個,並在主板上(管理驅動器)的成本多一點。
- The drives will make twice as much noise.該驅動器將高達兩倍噪音。 Hmmm. hmmm 。
- It doesn’t solve ALL backup problems: If I accidentally permanently delete a file, it will be gone on BOTH drives; if lightning hits the computer it could easily take out both drives.它並不能解決所有的備份問題:如果我不小心永久刪除一個文件,它將會消失於兩個驅動器;若閃電擊中計算機,它可以很容易地接納了兩個驅動器中。
I’m leaning toward…我傾向…
