Almost certainly. You'd need a marketing gimmick to let people know that this drive is optimised for speed. You'd need to let people know that this is easier than eSata or whatnot (and more available) and what they can expect over USB 3 and USB 2.

Add in some foolproof encryption and you've increased your market to anyone working in healthcare.

I wish there was a market for the opposite: not very fast (say, as fast as 7200 rpm hdds), but cheap and biiiig (2 TB) for a laptop. I'd buy that even if it was five times more expensive than a 2 TB HDD (just so I don't have to worry about moving parts).
