I purchased a base model rMBP for $1000 NIB. I absolutely love it, especially since I have been using a PowerBook G4 since my 2012 cMBP was stolen. The only issue is that the internal SSD sits at 128gb which for 90% of people (including me) is too little. In order to upgrade the storage I will need to either purchase a larger Apple SSD from eBay or a Transcend JetDrive Lite. This leaves me at a crossroads. Should I opt for a faster 256gb of internal PCIe storage for $215 or pay $140 for a slower 256gb or SD storage? I do use my SD card slot quite a bit but not enough to where it would be a big deal if I had to take it out. So what does the community think?
