Hey,
I've got two NAS and a bunch of drives. One EXOS 16Tb, two Barracuda 8Tb, one IronWolf 6Tb, on WD "white" 6Tb and on WD Red 3Tb. My main NAS is a desktop with +6 slots, my second NAS is a 4 bay Asustor.
Currently I don't use raid/parity of any kind... All drives are single volumes and it just sync's each drive from my main NAS to the second NAS, so I try to make the drive setup equal. However, the recent addition of the EXOS 16Tb kills that.
Since my main NAS is changing to a FreeBSD/TrueNAS with a ZFS pool, what's the best setup?
I was thinking maybe 8Tb+8Tb+6Tb+6Tb in the ZFS pool, then 16Tb+3Tb as single volumes on my second NAS. This way drives in the pool are as similar as possible in size and if parity wastes one drive, it will be about the same total capacity as the second NAS.
Does this make sense?
