RAID (redundant array of independent disks, originally redundant array of inexpensive disks[1][2]) is a storage technology that combines multiple disk drive components into a logical unit. Data is distributed across the drives in one of several ways called "RAID levels", depending on what level of redundancy and performance (via parallel communication) is required


据高人说,应用服务器等可以用RAID1, SVN服务器可以用RAID5,而数据库理想情况下应该用RAID10(非标准等级,LINUX自家的叫法)
