I think the majority of very large or very fast drives are in systems which don't (deliberately) power cycles often, in rooms where heat is an issue. And to spin up quickly take a larger power supply... 30 sec is fine with most users.
Couldn't find a spin-up time for the new Seagate 750GB drive, but the seek sure is fast!
I do use a 15K rpm drive in my workstation (hello git!), and the spin up
really isn't that bad. Less than 10 seconds for the actual spin up, I
would say.
