Hey, I've already upgraded my White Macbook to 4Gb of RAM, but now need to upgrade the Hard Drive. My mission is keeping it as a perfect clone of the content on my iMac to take to band practise, so I need at least a 300Gb hard drive.. Really 500.. Maybe more to be sure?! I use it entirely for music production, using Ableton Live. Lots of producing and recording clips etc on the fly. It seems a big Mac upgrade centre is based in Cambridge, where I live: Here is the list offered. http://www.macupgrades.co.uk/store/mach ... me=macbook Which hard drive do you recommend? Is 7200RPM a good idea for music production?
