I've just ordered a 2.2ghz MacBook Pro (4GB, 200GB 7200rpm), mostly for Logic use. I'll be using it out live using Mainstage, so reliability/smoothness is very important. So, for this reason I've decided to keep the machine 100% dedicated to music production, to give myself the best chance of a fully reliable and stable system. BUT, as it is such a powerful machine (and much more powerful than my main machine: a PowerMac G5 with 1GB RAM), I would like to use it for other things too - iMovie for importing/editing video, occasional internet use, and Windows XP/bootcamp, mainly for games like Bioshock/Halflife etc. My question is - can I get an external FireWire harddrive, 500GB or something, and divide it into 2 partitions. On one partition I'll put samples/audio etc. to use with Logic. And, on the other I'll install everything else (inc. a completely separate Leopard system). Then, when I'm doing the music stuff, I'll start up from the "music/clean" system on my internal HD, and when I'm doing all the other stuff, I'll start up from my external HD. Will this allow me to keep a fully clean system separate just for music use? Or will things get mixed up somehow anyway? And, if I do go down this route, will a 500GB Time Capsule drive allow me to use it as a wireless HD, and not just for Time Machine? If so, will the performance be much worse than FW800/400 by going wireless (802.11n)? OR, could I just split my internal HD into 2 partitions, one for music and one for everything else, each with its own system? Would that be effective in keeping the music system clean?
