Difference is 3 year vs. 5 year warranty, and higher claimed MTBF. It's my understanding the drives are identical internally, but the firmware is tuned slightly differently.
We all know the MTBF's on these things are wild guesses exrapolated from a relatively small and short term test on a number of brand new drives. Same internals but different firmware? We usually hear that "enterprise" drives have superior platters or servo motors or some such thing. If it's just firmware why wouldn't they just put that good firmware in all of their drives? I guess it all comes down to marketing and market segmentation as a means to drive up prices which happens all too often.
