Do you think if I get a USB 3.0 flash drive that the speeds will be almost as fast as the SSD in the MBP or will a SD card be faster than the flash drive. The flash drive may also be better to transfer storage since almost all PCs have USB but they may not have SD card slots.The SD card is noticeably slower but it depends on how you layout the storage. I think a 128 drive is short sighted. It may save a few bucks initially but if you find you need more space the cost to upgrade will be significant. If you decide to buy a different MBP the resale value of the 128 is much lower and the new machine will cost more. You can pay me now or pay me later.
