Linux RAID Performance On NVMe M.2 SSDs With EXT4, Btrfs, F2FS
Btrfs isn't doing too well, but at least EXT4 and F2FS are working out great with the soft RAID across two Corsair MP500 NVMe SSDs.
The Java-based BlogBench test that tries to simulate a blog web hosting type workload, EXT4 is out in front and doing much better than F2FS and Btrfs.
While running one Dbench client, the Samsung-originated Flash-Friendly File-System was out in front.
At six Dbench clients, F2FS remained much faster than EXT4.
