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

For the PostgreSQL performance the race tended to be led by F2FS and XFS file-systems on this Dell PowerEdge AMD EPYC server with Samsung SSDs.

Lastly for trying to sum up the otherwise diverse results is the geometric mean of all the Linux storage benchmarks carried out for this article. On a single Samsung 860 EVO SSD, the fastest file-system was XFS followed by F2FS and EXT4 while Btrfs with its default configuration (copy-on-write, etc) was the slowest. At RAID0, Btrfs and F2FS performed the best while at RAID1, XFS was the standout performer. The results with RAID5 and RAID6 were fairly close while when moving to RAID10, F2FS was much faster than the others.
