April 17, 20251 yr Hi, I've been using Freenas/Truenas Scale for some years now, thinking about migrating to unraid. Quick question. I have 4x8TB and 2x16TB hdd. I want to get most usable space out of this config. I'm guessing 1 parity drive (Must of course be 1x16TB) What do you guys think about this? All disks connected trough an HBA (It-mode) Regards Marius
April 17, 20251 yr Community Expert That seems sensible - you would have 48TB of useable space (4*8 + 16).
April 17, 20251 yr Author Thanks for the reply. Then my thoughts are right. And i will have the parity of 1 drive failure? So, if 1 drive fails, i can replace that and be up and running again within a day or two? Sorry for being a little noob on this...
April 17, 20251 yr Community Expert Just now, Marius_ said: So, if 1 drive fails, i can replace that and be up and running again within a day or two? You can be up and running immediately despite a drive having failed as Unraid will 'emulate' it using the combination of the other drives plus parity and act as if it were still present. What will take the day or so is rebuilding the contents of the failed drive onto another physical drive so you are back in a protected state.
