I haven't seen one yet, nor read anything other than the press release.
But my guesses are (1) perhaps these are the rebranded Hitachi drives we've been "waiting" for, and/or (2) they've limited media errors to something less than a 2-minute timeout, to make commercial NAS boxes happier.
EDIT: Oh, and I'll bet they finally changed the 8-second unload timeout to a more reasonable default value.
