Thanks for the reply. I unfortunately don't have an account or CC to use to sign up for E-E. Maybe it is time to look into that.

One issue with new drives is that in order to buy the Dell drives with the appropriate connectors, it is likely going to cost close to one third the cost of a new server!

The server in question is also a domain controller and runs another DB app, and is the file/printer server for the office too.

I have used Ghost for imaging before, but never Acronis, and haven't particularly had good luck with Ghost on RAID. Imaging seems to me to be a scary proposition and has a lot of potential for failure. I also do not have any disk to image to, as the intermediary location when going from old disk set to new disk set in the same system.

I'm also very hesitant to modify the existing RAID config. Are you suggesting turning RAID off and then adding it again after swapping drives? It would seem to me that any modification to the current RAID set will kill my existing drives and render the server unusable. Do I misunderstand? I am not a RAID expert by any means.

Thanks for your advice!
Tom
