A computing device for verifying data integrity is provided, comprising a memory controller configured to receive a plurality of original data blocks. Each original data block has an associated initial CRC value. The memory controller then segments and recombines the received data blocks into logic blocks, and calculates a new logic block CRC value for each logic block. The logic blocks are transmitted with their respective new logic block CRC values to a storage device, and the logic blocks are written to non-volatile memory of the storage device in a write operation. After the write operation, a combined CRC value is calculated for the logic blocks and a combined CRC value for the original data blocks, and compare the combined CRC values. The memory controller determines whether the combined CRC values match. When they match, the memory controller generates a verification response verifying the integrity of the write operation.

Device and methods for managing the data integrity of read and write operations

A method is directed to storing data in a non-volatile storage. The method includes writing sequentially at least a main portion of a data record in one or more logic blocks of an append-only storage zone of the non-volatile storage until the one or more first logic blocks are written full. The method also includes generating a first journal including a remainder portion of the first data record and a first journal entry for the remainder portion. A storage device control system includes a non-volatile storage and a controller for the non-volatile storage.
