Abstract
A data storage device comprises a storage array containing first data, a buffer containing RAID units, and a controller in communication with the storage array and the buffer. The controller is configured to receive a read request from a host device for a second data stored in the storage array, and determine an identifier associated with the requested second data. The controller is also configured to determine if the requested second data contains an unrecoverable error. The controller then accumulates first data, including a parity value, contained in the storage array associated with the same identifier as the requested second data in a reconstruction buffer, if the requested second data contains an unrecoverable error.
