Abstract
Provided is a method of writing data to a solid-state storage system, wherein the solid-state storage system comprises several logical disks. The method comprises the steps of: from each of the logical disks, allocating at least one idle logic block used for receiving parallel data, wherein each of the logic blocks comprises several logical pages; setting the logical pages with a same page number in respective logic block as one RAID stripe, wherein each RAID stripe is used for storing a set of parallel data and verification information associated with the parallel data; and when data in one of the logical pages is damaged, calculating and restoring the damaged data based on the other data and the associated verification information stored in the RAID stripe where the logical page is located. The present invention also provides a solid-state storage system for implementing the above-mentioned method.
