Abstract
The present application relates to a RAID optimization method and apparatus for Multi-Pass NAND programming, a computer device, and a storage medium. The method includes: obtaining a RAID optimization request for the Multi-Pass NAND programming; performing, by a RAID engine, encoding on cached user data of a corresponding RAID stripe during each Pass programming, according to the RAID optimization request of the Multi-Pass NAND programming; generating corresponding Parity data in real time through the encoding by the RAID engine; releasing a buffer area for storing the Parity after a corresponding Pass programming is completed, without waiting until all-Passes programming has been completed. According to the present application, aiming at a Multi-Pass programming scenario, RAID parity data is dynamically generated without buffering the corresponding parity data during each pass programming. The RAID parity data is generated in real time, so that a requirement on a memory of a SOC is reduced, a performance of a SSD is improved accordingly, and the cost is reduced.
