I need a high-performance ti-book HD, but which?

[Over Achiever]

Ok, I'm starting to plan ahead for buying and upgrading my ti-book. I like preformance, and I think that a 5400 rpm HD is good. However, it only comes in the 60 GB variety, which I don't need all the hard space for. So I have a couple choices (so far)...

1. Buy the model that has the 60 GB HD

2. Buy a model that has a 30 GB HD and buy an IBM TravelStar 40GNX 40 GB, 5400 rpm drive for an additional $110. But what can I do with the original 30 GB HD that came with the TI-Book?

3. Buy a firewire HD like the 40 GB MCE Transport Pro (5400 rpm) for an additional $349.

Any thoughts, any experiences with the IBM and MCE drives? Any other recommendations?

[EDIT]So are there 7200 rpm external HD out there? How bulky are they?[/EDIT]

[EDIT2]How quiet are these drives? My PC laptop makes a lot of clicking noises when its being accessed[/EDIT2]

it also comes in a 48gb version, not just 60.

oh yeah-


if you don't mind, you can get fast firewire drives. they would be external though.
