There is no 'standard' 5200rpm drive. I assume you mean 5400.

I think you're right about that. Both 5400 and 7200 are capable of 
feeding video more than fast enough. I'm not sure at what point the 
5400 would start to bog down, if ever (i.e., I'm not sure how it would 
hold up if you had, say, a pcHDTV card, along with another tuner).

Anyone? Aaron? I use dual 7200s, RAID striped, myself. And my system is 
still pretty quiet...
