Seagate Momentus 7200.3 320GB (ST9320421AS)

Category: Hardware

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

Hey,
Thanks for the post. Glad to know it works.

I was wondering why you suggested not to get G shock.
Also did you notice any battery life differences?

The MacBook Pro has a built-in “Sudden Motion Sensor” that disengages the drive heads in case of a fall.

Battery life should really be about the same — hard drive usage is the same regardless of storage capacity. As for its power-efficiency itself, I would imagine it to be as good or better than older drives since these are designed for mobile computing.
