9-Way File-System Comparison With A SSD On The Linux 3.17 Kernel

With the Flexible I/O Tester on the Corsair SSD, the EXT4 file-system was by far the fastest tested while NILFS2 and Btrfs were the slowest with their stock mount options. The older EXT2 and EXT3 were running around the same speed as ReiserFS and JFS for a second place tie.

With FS-Mark, JFS has a strong performance finish and was the fastest FS for this workload by far. This faster performance of JFS might be due to how it handles its journal writes, which in the past has been criticized for delaying the writes, which can yield increased performance numbers in these tests but risks potential data loss.

Of the file-systems working appropriately, F2FS was the fastest for FS-Mark.
