Difference between WD2500KS and WD2500AAKS

[godsizesnakeyes]

Going with a WD SE16 250GB hard drive for a system I'm building. Does anyone know what the difference is between the WD2500KS and WD2500AAKS models? Both are the same price at newegg and seem to have the exact same specs. I've even been to WD site and cant find any difference between them.

AAKS is a newer model and is the faster one.

KS is too loud.
