Hey all, looking at either buying an HP Mediasmart Server or a Thecus 4bay NAS. My question is in regards to RAID/Folder duplication. On the Thecus I can use RAID 5 and 4 1TB drives yielding a total redundant storage capacity of 3 TB. But it seems to a little unclear on how much storage I can expect from the Windows Home Server with Drive Extender. From what I've read, it's essentially JBOD with RAID 1... so 4 1TB drives would only yield 2 TB if I were to duplicate all folders (which is what I want to do, everything is precious to me)? Can someone clarify or confirm?
