Abstract
Systems, methods and/or devices are used to enable dynamic erase block grouping. In one aspect, the method includes (1) maintaining metadata for each erase block of a plurality of erase blocks in a data storage system, wherein a respective metadata for a respective erase block includes one or more characteristics of the respective erase block, (2) allocating a set of erase blocks, of the plurality of erase blocks, as unassociated erase blocks, (3) selecting two or more unassociated erase blocks in accordance with characteristics of the unassociated erase blocks so as to select unassociated erase blocks with similar characteristics, and (4) grouping the two or more unassociated erase blocks with similar characteristics to form a super block.
