What speed hard drive is in the mac mini?

Anyone know?

I think its 5400 rpm.

It's a powerbook-type drive, 4200rpm. The Macs Only site has tested a mini with a faster replacement drive (Hitachi 7200 rpm), as well as several memory configurations: www.macsonly.com, under the heading "How Fast Is It?"

I'll have to keep an eye out for a deal on a 7200rpm drive, I think the stock drive is really holding the systems performance back.

I read a review about the Mac mini in which they tried out a 7200rpm drive at http://www.macintouch.com/macmini/review.html . Hope this is of interest to you !!
