Designated file storage using Raid 1

Hi,

I’m new to Network Attached Storage systems and planning on buying a 2 bay NAS. I don’t know much about RAID but am keen to get 2 x 8TB WD Red NAS drives and use RAID 1 so there’s always a copy of each file on both drives in case of a drive failure.

This might sound like a completely dumb question, but it is possible to setup a NAS so that only half the capacity of the 2 x 8TB drives (4TB of each drive) acts as a RAID 1 storage, with the remaining 4TB on each drive (with a combined capacity of 8TB between the two drives) as general storage not protected by RAID?

That way I can save all my important files on the RAID system (protected) or save any files I don’t care too much about in general storage. Or is that just not possible, or recommended?

Thanks for any comments and help.

You could setup the volumes the way you propose. You would probably end up with three volumes, V1 (RAID), V2 (JBOD DISK 1), V3 (JBOD DISK 2). But I personally wouldn't worry about it. Set the whole thing up as RAID1. Then if you really need more space add a USB3 drive to the NAS.
