RIght now both Buy.com and Amazon.com have the Western Digital WD Scorpio
Black 500gb 7200rpm 2.5" SATA Hard Drive for Laptops or Desktops for $64.99,
with free shipping.
This seems to be the most reliable, fastest, and best reviewed laptop hard
drive on the market right now. I've been shopping for one for the past few
months - this is a 5 bucks cheaper than any reputable shop i've seen it at,
and at least $10 cheaper than newegg.
Your choice, Amazon or Buy.com:
