Ok, I know it stands for something along the lines of Just a Bunch of Disks... I was looking at a dual bay external enclosure that allows Raid 0, 1, or JBOD. Does JBOD mean that the two drives would be seen as a single "virtual drive" or simply 2 completely separate drives with their own drive letters? I'm hoping for the latter. I don't want RAID 0 b/c of this is for backup/archiving, I don't want RAID 1 b/c of wasting an entire drive, and I'm scared of JBOD because I assume I'll have no control over what files are stored on which physical drive. I'd personally like two drives in one enclosure, backup nearly everything on 1 of the drives and then selectively duplicate some of the backup stuff on the other drive but NOT all of it.

JBOD is used for spanning multiple disks into a single virtual disk. Unlike RAID 0, JBOD can be implemented using non matching drives. For example, you could span a 40GB, 20GB, and 60GB drive into a single 120GB "virtual drive". This method does not provide data redundancy.

This is true however if you setup Raid on Your JBOD then you can have redundancy. I am running 20T over 32 disks (some of different sizes) and it runs like a champ. But this is usually used for massive storage. Not just a few disks
