When I travel, I still uses a late 2013 MacBook Pro Retina for photography when traveling: downloading images and videos, preparing blog entries, etc.
But I use it mainly to download images and back them up to external drives, safe in the knowledge that I have everything in one place, and backed up too.
The issue is that the MacBook Pro Retina has a 500GB internal SSD (500GB usable despite Apple 512GB claim) and that combined with OS X and certain necessary files, 280GB of the capacity is always in use and cannot be reduced, leaving only about 220GB available for storage.
That 220GB remaining capacity has become a headache with higher resolution cameras and big raw files. While an external drive can be used for overflow, it’s much nicer to download everything to the internal SSD, and to backup it all to matching external(s)—a tidy solution with everything accessible at once.
Until now, there was no SSD upgrade path. Now there is: OWC Introduces 480GB and 1TB SSD Upgrades for 2013 and Later MacBook Air and MacBook Pro Retina.
The question boils down to figures: spend $3578 (with tax and AppleCare) to get a new laptop with a 1TB SSD, or spend about about $600 to upgrade to a 1TB internal SSD. That’s a $3000 difference and the current laptop otherwise serves my needs just fine.
