Second HD - raid or extra
I set up my Jellyfin NAS just as hard drives sold out, so until now I’ve been using only a single drive (4TB). I recently was able to get a second one at a reasonable-ish price but when I put it in the NAS I accidentally configured it for a raid array. I’ve already copied all my movies and shows to the drive, and it’s at about 3.5T usage.
Should I backup&delete the storage volume and start over with two drives worth of storage or is the redundancy from the raid better even though I only have one drive worth of storage space (until I can get a third, that is)?
