SSD-optimized File Systems
Usually the same file systems used on hard disk drives can also be used on solid state disks. In most of the cases it is useful that the file system supports the TRIM command which helps the SSD to recycle discarded data. There is no need for the file system to take care of wear leveling or other flash memory characteristics, as they are handled internally by the SSD. That being said, some flash file systems using a log-based design (F2FS, JFFS2) will help reducing write amplification on SSDs (especially on situations where only very small amount of data is changed, such as when updating file descriptors).
While not a file system feature, operating systems must also align partitions correctly to avoid excessive read-modify-write cycles. Other features designed for hard disk drives, most notably defragmentation, are disabled in SSD installations.
Listed below are some notable computer file systems which are optimized for solid-states drives.

Famous quotes containing the words file and/or systems:
“I have been a soreheaded occupant of a file drawer labeled “Science Fiction” ... and I would like out, particularly since so many serious critics regularly mistake the drawer for a urinal.”
—Kurt Vonnegut, Jr. (b. 1922)
“What is most original in a man’s nature is often that which is most desperate. Thus new systems are forced on the world by men who simply cannot bear the pain of living with what is. Creators care nothing for their systems except that they be unique. If Hitler had been born in Nazi Germany he wouldn’t have been content to enjoy the atmosphere.”
—Leonard Cohen (b. 1934)
