ZFS RAID Performance

[matthew]

Say I have 3 drive slots. For random I/O would I be better off with ZFS RAID1 over 2 drives or ZFS RAID5 over 3 drives? Last time I tried to setup RAID1 over 3 drives on Proxmox it would not work.

If ONLY the Performance is key: ZFS Mirroring with three drives

Read Performance = ~ 3 * single Drive (because distributed over all drives)
(Sync) Write Performance = 1 * single Drive (write is only finished if data is written to all drives of a mirror)

Best regards
