Thanks to a growing media and photo library my 250GB MBP drive is almost at its capacity. Ive researched drives and have settled for the 500GB WD Scorpio Blue as a replacement but its now dawned on me that there could very well be an alternative solution. Would I benefit from storing my photos and music on a NAS and freeing up space on my laptop? Im not in strong favour of this as I do prefer having my music on my laptop when I travel but I can be persuaded. The only backup of my home folder I have is off-site through Carbonite so would this still continue to function with a NAS? I would also like to start using Time Machine and an on-site backup. Is a NAS the way to go or should I stick to a external drive and backup my machine through Time Machine?
