[maxmsp] [slighty OT] best USB 2.0 Harddrive for live performance?

My apologies if this has come up before... I searched the archives and didn't find anything that seemed particularly relevant.

I just picked up a new MacBookPro, and I'm looking for an external harddrive (USB 2.0) that would be well suited for live performance.  I'll want to play audio and video files off the drive, and record to it as well.

Does anyone have any recommendations or wisdom to share in this area?  I know I need a 7200 rpm drive, but other than that I'm not sure.  Size isn't as important, but I'd prefer a minimum of 100 GB.

Thanks,
Dan
