ReadyNAS Ultra 4 Plus Expansion Help
Hello. A couple questions, and I apologize as I am sure theyve been asked before. My search wasnt of any help. I have used the ReadyNAS Ultra 4 Plus for a few years now for movies and music with (4)...

The ultra can't expand the space until you insert the second 3 TB drive. After the initial resync, it should prompt you to reboot, and then the volume should expand by 1 TB.
There are two limits to expansion:
(a) the volume can't expand over 16 TiB. You are nowhere close to that limit.
(b) the volume can't expand more than 8 TiB from the initial size. You could reach that eventually, but you are not there yet. If you started with a single 1 TB drive ,you'd still be able to expand to 4x3TB.
As far as backup goes, your data is never safe if it is only stored on one device. RAID arrays (and NAS) can fail in ways that lose your data. So I do strongly recommend that you put a backup plan in place. You should also consider a UPS.
Multiple USB drives are commonly used for NAS backup (though you might need to split your movies into two shares). I use other NAS myself.

Thanks, I have inserted the second 3TB and its resyncing. Can you suggest a decent UPS? Currently only use high Joules rated Surge Protectors but have looked at some UPS machines but honestly dont have much knowledge on those.
