My first NAS: Can I have one disk without any redundancy?

[Prasant J]

Hi,

I'm planning to build my first NAS.

I plan to have 2 disks in RAID configuration for redundancy. This is for my critical data.
Apart from this, I also plan to have ONE more disk, but without redundancy. This is for my non-critical data.


Is it possible to have the above configuration?


Any inputs will be of help!

Regards, Pj

Yes, that is 100% possible.

Food for thought:
If they are all the same size, you also could build a raidz1. That will give you the same space in one pool, so your pool will have double continuous space and allows for one HDDs fail without losing data.
In other words:
2x2TiB HDDs in mirrow and 1x2 TiB HDD = two pools of 2 TiB each.
3x2 TiB HDDs in Raidz1 = one pool of 4 TiB usable with 2 TiB parity.

Coming from a guy who lost 6 years of data...please have a backup pool! If you are going with RAIDZ1 with 4TB storage then you can just add a single 4/6TB disk to be your backup.
