Embodiment Construction
[0074] This application proposes a log recording method, loading method and device thereof, which split the FTL table into multiple FTL blocks, each FTL block corresponds to a corresponding FTL frame and a log frame, and the FTL frames belonging to the same FTL block and The log frames form a linked list respectively, so that when rebuilding the FTL table, the amount of data writing can be reduced and the recovery speed can be improved. When an abnormal event occurs, by changing the storage ratio of the log frame in the log, the log usage efficiency can be improved as much as possible, and when rebuilding the FTL table, the data in the FTL table can be quickly restored through the setting of the linked list. When updating the FTL table, updating the FTL table in reverse order can make the recovery of the FTL table faster when an abnormal event occurs.
[0075] Of course, implementing any technical solution of the present application does not necessarily need to achieve all the...
