Abstract:
In some example embodiments, a method of organizing an address mapping table of a flash storage device based on Logical Block Address (LBA) size may comprise: identifying an extent of correlation between the LBA and flash page sizes, wherein the extent of correlation indicates greater or lesser extent; computing a total number of entries in each meta page of the table; and/or organizing the table with the total number of entries. In some example embodiments, a method of organizing an address mapping table of a flash storage device based on LBA size may comprise: determining flash page size of the flash storage device; determining the LBA size; and/or comparing the flash page and LBA sizes. When the flash page size is greater, the table may be organized based on flash page size. When the flash page size is less, the table may be organized based on LBA size.
