Hi all ! I've recently bought a new macbook specifically for being on the road DJ'ing with. I have over the years had large external drives to carry around all of my music but i'm getting increasingly annoyed with having to carry around an external drive with me. I'm looking to switch from using a 750gb external and have everything on an internal hard drive which means upgrading the mac's standard 250gb to something substantial. I'd ideally like to upgrade it to a 1tb / 750gb drive to store all of the music I have but i'm a little lost with drives that will fit the macbook's bay. Can anyone shed some light on the dimensions of the drive I should be looking at and offer any suggestions of good 1tb / 750gb drives? Thanks in advance.
