I have a MacBook Pro 13" 2015. I got a Samsung 970 with this small adapter: https://www.amazon.de/gp/product/B073F9LDD5/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 When moving my macbook and especially touching the bottom of my macbook, it often got kernel crashes. The ssd also often switched between 2x and 4x lanes… I later bought the ST-NGFF2013-C thanks to this thread and since then no more crashing. Very happy. I only feel the macbook loses around 1-2 hours of battery compared to the original apple ssd. Is there a a m2 ssd with less power usage?
