Will this work with JBOD RAID?

I'm wondering if this card will work in a Concatenation (JBOD) RAID config. Or will I have to get the sonnet RAID card?

A JBOD is not a RAID. With OS X, you can always do a software JBOD, but beware: lose one disk, lose all data.

Oh, I didn't realize that. I thought it was RAID 0 that if one of the drives failed, all the data is gone. And for JBOD, only the data on the drive that failed is lost. Also, does that mean I can get a regular IDE card for my PC and do JBOD as well?

Yeah, that's true for RAID 0 as well. In theory only the data on the failing drive of a JBOD is gone, practically I haven't heard of a successful recovery of data from a damaged JBOD. You can do that in software on Windows and OS X with any ATA card and combination of hard drives. However, you shouldn't underestimate the issue of harddrive failures: if the probability for harddrive failure within four years is 2 %, then the probability that at least one of the four drives fails in four years is roughly 7.8 %. So make sure to keep that in mind before creating a JBOD or RAID 0 volume.
JBOD have only a few advantages compared to a RAID 0, e. g. you can combine drives of different sizes. On the other hand, a RAID 0 is a lot faster, especially with more than two drives. However, keep in mind to back up your data.
