Is there really that big of a difference between the two speeds? I will use this computer for some online games and app development for iphone. Do you think I will need the faster hard drive? Is it possible to install a second hard drive into the mac mini after I purchase it??
Mac mini, Mac OS X (10.7)
It absolutely will make a difference. Of course, unless you're running the two speeds side-by-side, it's going to be hard to compare. But, ultimately, yes...you will see better performance with a higher RPM disk. you may be better off upping the amount of RAM in your system, and if you're planning on gaming a lot, get the mini with discrete graphics instead of the integrated.
To your second question, take a look at ifixit.com. They've already posted a teardown of the new mini, and there is room for a second 2.5" drive in there. You just need to find the cable that connects the drive directly to the system board.
5400 rpm or 7200 rpm for new mac mini??
