Seeking advice on planning hdd set up for macpro Main use will be internet etc - only very occasionally handle photo/video files. Presently have eMac G4 (what a great machine! thanks Apple - 15 years without missing a beat). Only have an external hdd at present for very infrequent clone(and video files on second of two partitions) - slack of me I know - I must lift my game on back up. Want to add 2 drives to existing installed drive - at least start off with 3 but wondering how I should use them - should I think it wise for even low-end user such as myself to seperate my working files from system&apps? I was only considering maybe using Time Machine and perhaps cloning but wondered how exactly I should divide functions between the hdds (and partitions ?). Anyone with suggestions appreciated.
