Data storage devices are provided according to various embodiments of the present invention. In one embodiment, a data storage device comprises a host interface, a buffer, a storage media interface, and a data manipulation engine. The data manipulation engine comprises a receive pipe configured to read first and second data blocks from first and second locations in the buffer and to check the validity of the first and second data blocks, an arithmetic logic unit configured to perform a logic operation on first and second user data of the first and second data blocks, respectively, to generate third user data, and a transmit pipe configured to receive the third user data from the arithmetic logic unit, to generate and append a third checksum to the third user data to produce a third data block, and to write the third data block to a third location in the buffer.
