 This means that file system does not need to manage wear leveling or other flash memory characteristics, as they are handled internally by the SSD.Some flash file systems using log-based designs (F2FS, JFFS2) help to reduce write amplification on SSDs, especially in situations where only very small amounts of data are changed, such as when updating file-system metadata.While not a file system feature, operating systems should also aim to align partitions correctly, which avoids excessive read-modify-write cycles.
