SOLID STATE DISK USING METHOD AND APPARATUS

摘要

A solid state disk using method includes: determining a latency of the data block to-be-operated according to a load balancing table of the solid state disk; determining whether the latency of the data block is greater than a warning value, where the warning value is less than a typical latency, which is a preset latency indicating an operation on a data block in the solid state disk fails; and not performing the operation on the data block if the latency of the data block is greater than the warning value. By using this method, real load balancing from the perspective of physical property is achieved, bad blocks are reduced, use of reserved blocks is reduced, thereby prolonging the service life of the SSD.

主权项

1. A solid state disk using method, wherein a load balancing table for recording latencies of data blocks of the solid state disk is preset for the solid state disk, and the method comprises:
when an operation needs to be performed on a data block in the solid state disk, determining a latency of the data block to-be-operated to-be-operated according to the load balancing table, wherein the latency is a time duration for performing the operation, and the operation comprises an erase operation or a write operation; determining whether The latency of the data block to-be-operated is greater than a warning value, wherein the warning value is less than a typical latency, and the typical latency is a preset latency indicating that an operation on a data block in the solid state disk fails; and prohibiting performing the operation on the data block to-be-operated if the latency of the data block is greater than the warning value.
