RAID空袭
RAID is a computer acronym meaning “Redundant Array of Independent Disks.” RAID是电脑的缩写,意思是“独立冗余磁盘阵列” 。 Wikipedia维基百科 . 。 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.在这种情况下我们谈论的“镜像”磁盘,其中一个最简单的RAID配置,其中两个相同的磁盘包含相同的数据,以便可以继续经营,如果其他失败。 Since they contain the same data the second disk doesn’t add any disk capacity, but it does add reliability.因为它们含有相同的数据,第二个磁盘不添加任何磁盘容量,但它确实添加的可靠性。 Pros:利弊:
- The hard disk is MUCH less apt to crash.硬盘要少得多容易崩溃。 Only people who have experienced a crash can fully appreciate this.只有人民谁经历了崩溃,可以充分理解这一点。
- Perhaps I can get away with less backup, eg only back up the most sensitive data.也许我可以摆脱与少的备份,例如只备份起来,最敏感的数据。
- Or, I can buy a THIRD drive and或者,我可以购买一个驱动器和第三 hot-swap热抽换 it, so the swapped-out drive is the backup.它,所以对调出驱动器是备份。
- I’d enjoy the experience of setting it up and using it.我要享受的经验,设置和使用它。
Cons:意见:
- It’s more expensive: I need two drives, not one, and the motherboard (which manages the drives) costs a little more.它的更昂贵的:我需要两个驱动器,而不是一,与主机板(管理驱动器)的费用多一点。
- The drives will make twice as much noise.该驱动器将作出的两倍多噪音。 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.它没有解决所有的备份问题:如果我不小心永久删除文件,它将会消失在两个硬盘;若闪电击中电脑,它可轻易拿出两个驱动器。
I’m leaning toward…我倾向…
