Well I bit on the 7200.7 ultra with 8mb cache. Got it for $60 after rebate, so I'm not too worried. It was either that, or a Maxtor 120GB sata for $120.
Here is my HDTACH, i ran it a couple times to make sure it was accurate:
the access times are higher than the sata one. i wonder if it is on the quiet AAM, if i can turn it to performance.
