With the Startup-Time test, developed by the kernel developers working on the BFQ I/O scheduler, to some surprise ZFS On Linux 0.8.1 dominated these early tests. ZFS both running on one Optane 900p and in the RAIDZ configuration was easily the fastest, even outperforming the likes of the Flash-Friendly File-System (F2FS) and others. EXT4 and XFS tended to be the slowest. Again, all these tests were done on the Optane 900p drives except for the lone "EXT4 Samsung 970 EVO 500GB" run tossed in for additional reference.

In the case of the basic SQLite benchmark, meanwhile, the F2FS file-system without any RAID configuration led to the fastest performance but by incredibly thin margins.
