http://www.wdc.com/en/products/products.asp?driveid=410 wondering if anyone has experience with this unit. I was totally ready to buy it but received some conflicting news in regards to replacing it's drives. My question is whether or not I am able to buy the 1TB version (2x500GB) and buy 2 1TB drives and pop them in and it work the same way. Anyone try this yet? I am drawn to this particular solution because it offers no brainer raid solution and the prospect of being able to swap drives in. Any thoughts or suggestions?
