Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS

In the case of random read IOPS, EXT4 was the fastest followed by F2FS. ZFS surprisingly exhibited the slowest performance, coming in even behind Btrfs.

Sequential read performance with FIO was led by F2FS and ZFS.

And sequential writes for FIO was topped by F2FS in RAID0 and effectively tied by Btrfs, XFS, and EXT4 in their RAID0 mode.

FS-Mark was initially led by F2FS in RAID0...

But when shifting to four threads of FS-Mark running, XFS RAID0 pulled out ahead.

F2FS and XFS continued duking it out in the other FS-Mark configurations.
