Which Raid would you choose and why?

[hameedabdul1]

I'm building a NAS and, I'd like to know, which raid I should use. I would like to be able to store at least 40 TB, with the rest being left as backup. (80 TB NAS). I'm probably using UNRAID, so, send help, plz?

If you're using Unraid, then you're using Unraid. It doesn't have any levels, like e.g. Unraid1 or Unraid5, just the one and only.

What type of things are you storing?

UnRAID does not use traditional RAID it uses it's own implementation where the data does not get striped across the drives. If you want opinions on different RAID levels you'll need to pick a different OS.

You can use ZFS on UnRAID, but it means you cannot use the UI for doing your Array & SMB management. In which case i'd create a raidz or raidz-2 depending on the redundancy you need. If you're using the UI functionality of UnRAID for the array, then as the others have stated you have no choice but to use their system which has contiguous files on single drives.

 

Perhaps consider Debian/Ubuntu + Webmin/Cockpit, and do a ZFS or traditional MD raid, that will give you flexibility on how you can configure it.

I see. Well, people have confused me very much. Thanks!

How many drives?

 

If you have 8x10TB, Unraid with 2 parity drives gives you 60TB usable, but the speed of a single drive.

 

If you need speed, RAID10 would give you 40TB usable with 8x read and 4x write speeds compared to a single drive.
