Let's just call it at this pointI never implied that the 40 Gig was BC. ANy reasonable person would assume that it was not from my post.
IMO your post wasn't explict enough for the 'what are the differences' request it was responding, and mine are aimed to be informative but are clearly bating you into responding, it's just a downward spiral from there.
It's all good, we're more or less on the same side here, I apologize for taking it as far as I have.
