Linux 5.5 SSD RAID 0/1/5/6/10 Benchmarks Of Btrfs / EXT4 / F2FS / XFS

When running SQLite in these different configurations, EXT4 and XFS were tending to be the fastest followed by F2FS and then Btrfs with its default CoW behavior performing much slower.

But when running eight copies of SQLite concurrently, F2FS saw a big hit to its standing and was now at some RAID levels performing comparable or worse than Btrfs. XFS meanwhile was tending to perform the best.

For random 4K writes with FIO, XFS tended to perform the best while Btrfs and EXT4 were performing well at some RAID levels. F2FS was tending to perform the worst in this test case.

The sequential read performance was interesting with Btrfs doing much better at RAID10 than the rest but for the other RAID levels tended to be led by F2FS and XFS.

Or in the case of sequential writes, it was led by XFS except at RAID0 where Btrfs was performing the best.
