For example, you can protect three devices with RAID-Z (RAID-Z 1); with four devices, you can use RAID-Z 2 (doubleparity, similar to RAID6).
例如,您可以通过RAID - Z (RAID - Z 1)来保护三个设备;对于四个设备,您可以使用RAID - Z 2(双重奇偶校验,类似于RAID6)。

Other RAID levels include RAID-5, which includes block-level striping with distributed parity codes across disks, and RAID-6, which includes block-level striping with double distributed parity.
