EQUALIZING WEAR ON STORAGE DEVICES THROUGH FILE SYSTEM CONTROLS

摘要

Data stored in file blocks and storage blocks of a storage device may be tracked by the file system. The file system may track a number of writes performed to each file block and storage block. The file system may also track a state of each storage block. The file system may use information, such as the write count and the block state, to determine locations for updated data to be stored on the storage device. Placement of data by the file system allows the file system to manage wear on storage devices, such as solid state storage devices.
