So I purchased the new Mac Pro the moment they went on sale. At the time, I ordered it with the 512gb SSD thinking it would be enough. Well, between a 150gb Boot Camp partition and the remainder used for OS X, I have decided I want to get the 1TB SSD. Only problem is that despite the part being user replaceable, Apple does not offer to sell it, nor do several of the authorized Apple service centers I have called. I am hoping someone here has heard of a way of replacing the internal drive and can provide some advice. BTW - I have plenty of external drive space with both Thunderbolt drives and a very large NAS.
