JBOD arrays: do you lose it all, if one of the disks fails?

[pm]

This is more of a hypothetical question rather than something that I'm planning on actually doing, but I was wondering. If you set up a JBOD array ("Just a Bunch Of Disks" - it's a way of combining multiple differently sized disks into one massive virtual disk), and one of the disks in the array dies, can you still recovered the data on the rest of the array, or are you out of luck as you would be if it were RAID0.

You'll only lose the data on that disk, the others will be fine.

Basically it just makes all of the disks look like one big volume. There is the possibility that a file could get "striped" off of the end of one disk and onto another, but it would be the exception, not the rule, 99.9% of all your files, and possibly 100% if it has some intelligence built in would be on a single disk.

Easier Disaster Recovery: If a disk in a RAID 0 volume dies, the data on every disk in the array is essentially destroyed because all the files are striped; if a drive in a JBOD set dies then it may be easier to recover the files on the other drives (but then again, it might not, depending on how the operating system manages the disks.) Considering that you should be doing regular backups regardless, and that even under JBOD recovery can be difficult, this too is a minor advantage.
