The parity is computed by XOR'ing a bit from drive 1 with a bit from drive 2 and storing the result on drive 3 (to learn about XOR, see OR). After a failed drive is replaced, the RAID controller ...

whereas RAID 3 and RAID 4 are known for byte-level and block-level striping with parity respectively. RAID 2 is used for its high data accuracy, however, not used widely due to the complexity of ...

The first parity RAID topology wasn't RAID5—it was RAID3 ... equivalent group of traditional vdevs—for example, a draid1:2:0 on nine disks will perform near-equivalently to a pool of three ...

OpenZFS release 2.3.0 is out, and will be in Linux distros ... meaning it can tolerate the failure of a single drive; RAIDZ2 has dual parity, like RAID 6, with two redundant drives; RAIDZ3 has ...
