Abstract

A Redundant Array of Independent Disks (RAID) scheme can be used to allow recovery from a memory failure. RAID 6 can be used to recover data from up to two catastrophic failures. Typically, a hardware encoder is used to generate parities of the RAID 6 protection scheme, and a separate hardware decoder is used in the data recovery process. In an example data storage device described herein, some of the components of the hardware encoder are used to perform the data recovery process, thereby eliminating the need for a separate, additional hardware component.
