I have just bought a MAc Pro Currently it has the stock 320 Hard drive which i have partitioned into 2 volumes , one for boot and one for other. I have ordered 3 more internal HDs which i intend to use as follows: Raid Stripe hard drive 2 and 3 and use HD 4 for Time machine. My question is i am about to install parallels.( I need to use Xp for some windows specific software but plan to have very little data on XP. Lets say a max on the drive of 25gb. ) So should i install Parallels and XP and let it default to my boot vol or should i install it onto my "others" volume or should i wait until my additional hard drives arrive. I am not very techie and desperately trying to learn. Any help greatly appreciated.
