Abstract
The present invention is directed to systems and methods for opportunistically defragmenting a data storage device during garbage collection. During garbage collection, valid data is identified and cached in a buffer assigned to the garbage collection process. When the buffer has been filled or reached a threshold, the valid data in the buffer is then coalesced and rewritten back to the data storage medium. In addition, a translation table is reduced by updating its entries to indicate the new locations of the coalesced valid data.
