I've done some googling but haven't found a definitive answer of which is better the Hitachi Deskstar or the Deskstar NAS 4TB drive. I was surprised to see the NAS version alongside the regular deskstars at Fry's and the NAS was about 10 bucks cheaper. I would have thought the moniker NAS would mean a better drive but that's just my consumer instinct and not scientific.
I found one thread that said the NAS probably has a shorter error correction timeout to make it more suitable for raid use and that for desktop use the regular deskstar was probably better. Anybody have a suggestion?
Here's the thread I found:

Are there any differences between HGST's Deskstar (HDS724040ALE640) and Deskstar NAS (HDN724040ALE640) 4TB models? According to Hitachi's data sheets, they both feature 7200 RPM spin speed, 64 MB cache and a SATA-III interface. Pricing is also similar. The NAS model's data sheet also mentions rotational vibration sensor technology and 1 million hours of MTBF, so are they designed with a little more fault tolerance in mind?

They are designed to handle additional vibration and other firmware optimizations for multi-drive storage sub-systems-- small RAID setups and whatnot.
For desktop use you probably want the regular Deskstar, as the Deskstar NAS line almost certainly has a shorter error correction timeout optimized for RAID use, rather than a longer error correction period permitted for desktop drives.

Thanks, I've got five of the Deskstar NAS models in an internal RAID-5 array on an Areca 1882 controller and five of the regular Deskstars in an external Drobo 5D RAID which is used for overnight incremental backups (so not in constant use). So far, all is working well; and I'll monitor the situation over time.

FYI, we just got a box of NAS drives from HGST, should start testing soon. Most of it will be done within NAS systems, but we'll run some single drive numbers for you too for comparison. Like has been said though, I'd stick with the Deskstars for your use.
