Bought a 256GB new MBP but having second thoughts that I should have got the 512GB version. I do audio work and was panning on using my external 512GB SSD to host samples (orchestral libraries, piano samples, various other large intensive sample instruments for Kontakt, BFD Drums, etc). Then the 256 internal would host my OS and sessions that I'm currently working on, while using the cloud for backup of past sessions. Should I exchange the comp for a 512GB so I can have all my samples on the internal drive as well? I read that the internal SSD would be about 6x faster than external (3GB/Sec vs .5GB over USB-C). Not sure how much this will actually affect my workflow practically. What do you recommend? Upgrade to 512 just incase?
