Thanks, I'm aware of that. For this particular card it is either defective or the XO is causing errors since it is barely 3 months old and hasn't seen much use. It is gathering a good amount of errors by writing 1-2GiB randomly, so I hope I don't need to go as far as writing almost 1TiB before I find the problem.
