Have a little more information now. We currently have a 1TB raid
array, and it would be nice to get a second one with 1-2 TB on it. We
currently have a MegaRAID SCSI 320-2X (532) card controlling said raid
array, and it has a second channel open on it. So, it would be nice to
get a second array that would work on that card. It seems like if I want 
to use my old card, I have two choices. I can get a traditional scsi 
raid enclosure like this:

To get 1T you need about $1700 worth of drives, and the enclosure is
about $1200. Leaves lots of room for expansion.

Or, I could get a scsi to sata enclosure:

The case itself costs $2000. However, disks are much cheaper and
larger than scsi, and may be easier to find in the long run. I think
price-wise we are looking at similar costs in the short run, but
cheaper with sata in the long run. It includes its own controller, and
I'm not sure how that works with already having a controller.

Has anyone tried a scsi to sata sort of enclosure? Thoughts about scsi
vs. sata drives in general?

thanks,
