Some controllers has direct option "pass through to OS" for a drive, that's what I meant. I can't recall why we have chosen RAID-0 instead of JBOD, there was some reason, but I hope there is no difference with single drive.

Actually there is, filesystems like ZFS/BTRFS prefer to see the drive directly, not a virtual drive. I'm not sure you can change it now anymore but in the future, always use JBOD. It's also possible that you don't have the latest firmware on the 9361-8i. If I recall correctly, they only added in the JBOD option in the last firmware update On Thursday, 10/09/2020 at 08:52 Miloslav H?la wrote: Some controllers has direct option "pass through to OS" for a drive, that's what I meant.

I cannot verify it, but I think that even JBOD is propagated as a virtual device. If you create JBOD from 3 different disks, low level parameters may differ. And probably old firmware is the reason we used RAID-0 two or three years before. Thank you for the ideas.
