What mobile harddrive is best for my MBP?

[matmac]

Hi

I am thinking about getting a small portable harddrive for my MacBook Pro, to boot a windiws partition from, run games, programs etc. I guess fw800 is the best, and Lacie provides 2 options. A 100 GB 7200 rpm and a 120 GB 5400 rpm. My question is: would there be any significant difference between two, and are there anything i should be aware of??

The chosen harddrive will be running from my laptops battery.

Hope you can help me

just from HD perspective, i'd say the 7200 will provide the best performance...

sorry, i'm not sure about the power consumption
