Seagate Momentus 7200.3 320GB (ST9320421AS)

Monday, August 4th, 2008

I happened to be able to get a couple of the new Seagate Momentus 2.5″ 7200rpm 320GB laptop hard drives from PC Connection.

After a 20-minute upgrade following these instructions for replacing a MacBook Pro hard drive I ran xbench and below are the results, in case anyone cares.

A couple of tips:

  • Don’t get the drives with G-shock if you’re an MBPro user
  • No, there shouldn’t be any jumpers set on the drive.
Xbench Version 1.3
System Version 10.5.4 (9E17)
Physical RAM 4096 MB
Model MacBookPro3,1
Drive Type ST9320421AS
