RAID 1 refers to an exact copy (or mirror) of a set of data on two or more disks. According to Wikipedia, it seems that the RAID 1 configuration provides parity, striping or spanning of disk space across multiple disks. This is useful when read performance or reliability is more important...

In case of a disk failure in RAID 1, data recovery is straightforward as the system continues to operate using the intact mirrored drive. The failed drive can be replaced, and the RAID controller or software will automatically rebuild the mirror by copying data from the functioning drive to th...

RAID 1: 数据镜像, 也就是说每块盘上的数据一模一样. RAID 2: bit-level striping. 如果真是用在硬盘上, 可想而知性能会有多差, 基本没人使用. RAID 3: byte-level striping. 同样极差的性能, 因为每次读写都需要所有盘的参与, 即使是非常小块的数据. ...

Q1: What would happen if you convert back to RAID1 in case of a drive failure? A1: When a drive in RAID 1 fails, the RAID enters "rebuild mode". When the failed drive is replaced, it will automatically start cloning the data from the intact disk once it is replaced. Q2: Would you...
