I am not sure what you mean there about a benefit only if you needed to increase capacity... Even if you have a RAID 5 Array on a 3Ware card, you cannot just add drives to it. You would have to remove and rebuild an array (see below). To add capacity to a system without moving the data off of and back onto the drives, you would need something like the Linus Volume Manager, which can use RAID as its underlying storage if you would like... > > ---- Which leads to another question: > > If I have a Raid controller set up to handle the drives as a Raid 1, can I > later use the same controller and have it handle the drives as a Raid 5?

You can change it later, but that will wipe out all your data. So, if you use the same controller, you will need to reliably move all the data to another medium, remove the array, and rebuild it as a RAID 5. -- -Michael George Ideal Solutions, LLC ------------------------------------------------------------------------- Using Tomcat but need to do more?
