Abstract
A data storage device with fault-tolerant design. The data storage device has a RAID (Redundant Array of Independent Disks) engine that generates RAID checking code for user data requested in a write command. The user data is programmed to a non-volatile memory according to a target physical address indicated in the write command. The RAID checking code is programmed to the non-volatile memory according to a reserved physical address. The user data and the RAID checking code are programmed to a stripe of pages within a stripe of blocks.
