A few websites in Canada had that drive advertised for as low as $45.00 a week or so ago. It turned out to be a distributor pricing error and most people had their orders cancelled. I did hear of a few people getting them though. Sadly I wasn't one of them :(
I won a P55-UD6 from Gigabyte a few months ago and when I asked if I could exchange it for a board with SATA 3.0 and USB 3.0 they said sorry no can do. The board is still in the box waiting for me to get a CPU for it.
