Chosen Solution
I want to use Samsung MZ-JPU256T/0A1 SSD from MacBook Pro 13" Retina Display Late 2013 as external disk. What adaptor or enclosure should I buy? I found OWC Envoy Pro, but I think it’s too expensive.
Apple uses a custom interface so you’re kinda stuck here on what will work ;-{ OWC is the only source I know of that makes the needed carrier for the PCIe x2 & PCIe x4 Apple custom blade SSD’s. But you might find a used one on eBay for less! Often people recover their stuff and then turn-around and sell it as they don’t need it again.
