I've been looking at the video and it all seems fairly straight forward to the point that the only thing really holding me back is wanting to see some reviews on how reliable their batches are; it's worth noting as well that as long as you're careful during the break down of parts, if the 2TB card fails you always have your original drive.Not much, I only go in there when a guide tells me to and I know exactly what to type in.
