ZFS On Linux With Ubuntu 12.04 LTS
With another complex FS-Mark disk test, FS-Mark was the fastest for the HDD but the slowest for the SSD.
For the BlogBench workload, EXT4 and Btrfs were much faster than ZFS.
When running one Dbench client, ZFS was multiple times faster than Btrfs and EXT4, but like FIO, the results appear to be too good.
