Hard Drive: Western Digital Caviar Green WD6400AACS 640GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive (bare drive) - OEM
$62.00 After Discount w/free shipping from newegg, slickdeal

Hard Drive #2: Western Digital Caviar SE16 WD7500KSRTL 750GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive
$139.99 - $7.00 instant rebate w/free shipping (not very slick at the time, but I wanted one) = $132.99

So, if you haven't seen my other monster post, I'm building a new desktop. I just got the Green drive and had totally forgotten about the SE16 I had in a external enclosure.

1.) Is there some kinda discontinuity with WD's naming strategy? By that I mean is the WD7500KSRTL the same as the WD7500AAKS? It seems like I heard about something like this recently. Any links to review posts or such for this drive (or the other one for that matter) are appreciated, seems like I wasn't finding them right off the bad like I figured.

2.) Which would you run the OS on, and which would you use for data? Once I get the specs/review data I'll be able to decide this as well, but I'd like to hear your side too.
 
Not sure about #1, but for #2 I'd use the Green Power for the storage drive since it's designed to save power when not in use. If it's your OS drive, it will always be in use. Not to mention that it's performance probably won't be as good as the 700GB. Not that it would be necessarily noticeable, but that's just what I'd do.
 
I think, WD7500AAKS is the model number of the drive, and what you will see if it's sold as a OEM drive, bare drive.

WD7500KSRTL, is the same drive but sold as a retail kit. Nice colored retail box liked you'd see in Best Buy, cables, screws, paperwork etc.

Thanks for that clarification. I'll do a more fair comparison now. Will be much more straightforward with this fact.
