Abstract: A computing system for verifying data integrity is provided, including a host device comprising a memory controller, and a storage device. The memory controller receives original data blocks, each having an associated initial CRC value. The memory controller then segments and recombines the data blocks into logic blocks. The storage device is configured to write the logic blocks to its non-volatile memory of the storage device in the write operation, calculate a new logic block (LB) CRC value for each logic block, and calculate a combined LB CRC value. After the write operation, the memory controller combines duplicated copies of a given CRC value for each of the original data blocks, then combines them together to calculate a combined segments CRC value, and compares the combined segments CRC value to the combined LB CRC value. When the combined CRC values match, a verification response is generated verifying data integrity.

Abstract: The present disclosure provides a data processing method, a device, a computer apparatus and a storage medium, wherein the method includes: in response to a target disk receiving at least one write request within a preset time period, determining a size threshold value for classifying a data update type according to a size of write data respectively indicated by each write request; determining a data update type corresponding to each write request according to a size of each write request and the size threshold value; dividing write data of the write request to obtain a data block according to a preset data block size, and caching the data block in a cache region of the target disk corresponding to the data update type, the target disk has multiple types of cache regions configured therein, different cache regions are configured to support caching of data with different update frequencies.
