Abstract
Just-in-time segment cleaning obtains the location of blocks of a storage system predicted to be targeted by a future write operation and cleans the blocks targeted for the future write operation prior to the occurrence of the future write operation. In one aspect, just-in-time segment cleaning is performed in proportion to previous user-initiated write operations. In another aspect, just-in-time segment cleaning applies a cost analysis determination to minimize the work of cleaning.
