OK, So I have hade my new mac pro for a few weeks now, and I love it. I have alredy upgraded my RAM and added a second HD. The Western Digital 640AAKS Thanks to all of you MacRumors's members. I'm using the new WD640 for my main boot drive. I have partitioned the original Seagate 320GB. One patron is for a second install of OS X. And soon, Windblows. The second partition I have set aside for storage. Right now, I have All the mac pro user's, iPhoto and iTunes folders stored on the second hard drive. My son and I, are also accessing our gaming collection from the second drive. Am I taking proper advantage of this second drive? Performance wise. Should I move or store each individuals home folder to the second drive, instead of just iPhoto and itunes as individual folders.
