摘要： An indication is received that a word line has been read. The word line is part of a plurality of word lines (in solid state storage) which is divided into a plurality of groups. It is determined which group is associated with the read. A count of consecutive, at least potentially uninformative reads is updated based at least in part on the group associated with the read and a group associated with a prior read. It is determining if the count is greater than a threshold and in the event it is determined the count is greater than the threshold, a read disturb check is triggered.

摘要： An access instruction which includes a logical block address (LBA) is received. A first-level table is accessed to obtain a first-level table entry associated with the LBA. From the first-level table entry, a location associated with a second-level table on solid state storage media is determined. The second-level table is accessed at the determined location to obtain a second-level table entry associated with the LBA. From the second-level table entry, a physical block address corresponding to the logical block address is determined.

摘要： A plurality of write data is received and combined to obtain backup write data. The plurality of write data is stored in storage. On a storage controller, the plurality of write data is released without waiting for a confirmation associated with writing the plurality of write data to the storage. The backup write data is stored.
