BACKGROUND

Fragmentation of a memory of a storage system can reduce performance of the storage system. Such fragmentation can occur when a host writes an update to a file previously stored in the memory. Over time, the level of fragmentation can increase, resulting in an increased degradation of performance. In order to increase the performance of the storage system, electronic devices, such as personal computers, can perform a file system defragmentation operation, which will be useful only if logical addresses of files are fragmented
