一、何谓RAID? RAID是Redundant Array ofInexpensive(or Independent)Drive的英文缩写,它是将多块硬盘连成一个阵列,然后用特殊的方式写盘,有效地防止了一块甚至多块硬盘损坏的情况下数据丢失。二、RAID技术级别目前RAID技术的级别分为以下几种: 1、RAID0 也就是Data Stripping数据分条技术。数据被分条存储在多块物理硬盘上,因为相临的数据块存储于不同的硬盘,所以系统能同时访问多个数据块。这样就提高了系统的性能。当然,使用RAID0技术至少要两块硬盘。而且,RADI0技术是不容错的,也就是说当任何一块硬盘出现故障时,都
First, what is RAID? RAID is Redundant Array ofInexpensive (or Independent) Drive abbreviation, it is more than one hard drive into an array, and then write the disk in a special way, effectively preventing one or more pieces of hard disk damage Under the data loss. Second, the level of RAID technology The current level of RAID technology is divided into the following categories: 1, RAID0 Data Stripping is also the data stripping technology. Data is stored in stripes on multiple physical hard disks. Since adjacent data blocks are stored on different hard disks, the system can access multiple data blocks at the same time. This improves system performance. Of course, using RAID0 technology at least two hard drives. Moreover, RADI0 technology is not fault-tolerant, that is, when any one of the hard drive failure, both
