RAID 6

What Does RAID 6 Mean?

RAID 6 is a type of RAID level that utilizes block-level striping and distributes two parity blocks on each disk within the array.

Techopedia Explains RAID 6

RAID 6 primarily has the ability to continue operations even if it faces two concurrent disk failures. This is achieved through the dual parity block or drive in RAID 6 providing enhanced fault tolerance and enabling RAID operations to continue even if it encounters a failure. RAID 6 write operations are slower than RAID 5, as it has to write to an additional parity block. A RAID 6 configuration has a minimum of four drives.
