Decisions... decisions... I know I keep on saying it, but I really think I'm close to getting my new main system (and hence my development system) sorted, and I think I need to buy one of those cages too. If you did get those two 8TB drives, you could still have your 8TB 3-way mirror without needing any more bays/sata-ports. My problem, of course, is if I'm playing with raid layouts I need as many disks as I can cram in :-) I'm counting 6 tucked away in my drawer, which means I'll almost certainly need to add an add-in 4-way sata card, and as those drives are a mixture of 500GB and 1TB, I'll probably split the 1TBs into 2x500GB and ignore md complaining that I have multiple components on the same physical disk ...
