The 7200.11 dont buy.
The 7200.12 1TB was rated a "kick ass" 9 by maximum pc.
what matters is how the drive performs after a year. magazine review writers have minimal information about longevity.
that's where the Newegg reviews are helpful - a rash of DOA's is something some potential customers want to know about.
the problem is, it's possible to game the Newegg reviews. you don't know if it's a genuine customer with a bad drive, or a competitor of the drive manufacturer performing "web relations" work.
