My question is this:
I defo want to use raid 5 because I'll cry if a hdd fails and I lose everything but I would like to know if there is a way that I can still merge 3 drives together to create one volume like in raid 0 so I just see one big 12TB drive? |
Yep - that's what RAID 5 looks like, RAID 0 except losing some capacity to the parity data. Both stripe data across disks so you see a single logical drive regardless of the number of physical drives.
You should be aware that you're going to lose 1/3rd of the entire space to parity data though, and that RAID 5 isn't exactly incredible as far as recovery of data goes. You may find that you'd rather simply back it all up for performance, or if you really want to be secure and don't mind losing the space use RAID 1+0.
Incidentally your storage requirements are insane. I can't even fill a single 3TB drive let alone 2 of them! Then again maybe your storage requirements are normal and I just don't have much content locally, I'm very 'cloudy'.
