I've got a 2016 base nTB 13 model and am toying with the idea of swapping for a base 2017 nTB 13 model. Prices are similar since although the 2017 has CPU improvements, it's SSD is half the size. Much of the reason I want to upgrade is for that better CPU (I'll be using fcpx occasionally). However I also know that the write speeds on the 128gb SSD are half the speed. Will this have any adverse effects other than copying files taking twice as long. Since read speeds are the same, the boot time and app loading time should be equal correct? Thanks.
