Abstract
A storage system determines a memory fragmentation level for each of a plurality of logical block address ranges. The memory fragmentation level for a given logical block address range is determined according to the number of memory senses required to read that logical block address range in its current state of fragmentation and the number of memory senses required to read that logical block address range assuming no fragmentation. The memory fragmentation level correlates to the sequential read performance for that logical block address range in that an increase in the memory fragmentation level results in a decrease in sequential read performance.
