I'm wondering about aftermarket hard drive upgrades for the Mini 311. I've been searching around, however unsuccessfully, for some details about the stock HP 160GB SATA 5400rpm drive. Is it a 1.5Gb/s or a 3? I would like to bump it up to a 250GB SATA 7200rpm after purchase. Any concerns or insight you might be able to offer would be a great help.
