I also have the Seagate. It is very quite while running. I don't notice the sound unless I listen for it. 5 year warrantee is a plus.I've got the Seagate, and I have to say I'm happy with it. It's pretty zippy for a 5400 drive. ......
TheJayWay & heySparkey how have you both found the battery life of your macbooks now your using the momentus compared to the factory drive you had?
personally id go for the seagate, they tend to be really reliable.. tho so are the hitachi's.
Some of the new 7200rpm drives are designed to use about the same power as the older 5400rpm drives.7200rpm will be a bigger battery drain though right? i like not having to depend on the mains...
