Abstract: A method for increasing performance of a recycle operation in a solid state drive, comprising the steps of (A) creating an empty physical-to-logical address map in a memory having a plurality of entry locations, (B) filling one of the plurality of entry locations with a physical page address associated with each data write operation to a block, where the block has a plurality of pages, (C) writing the physical-to-logical address map to a last of the plurality of pages during a write to a second to last page of the block and (D) initiating a recycle operation of the block by reading the address map to determine whether the pages contain valid data.
