Chosen Solution

I need to be able to read the data from a SSD drive from a mid 2014 15 inch MacBook Pro Model A1398 EMC EMC2876. The machine it was in is ruined because of a coffee spill. I know these drives  have a proprietary interface. What type of adaptor/converter do I need to connect it to another Mac to retrieve the data?

You can get this case to hold the SSD: OWC Envoy Pro Portable, Bus-Powered USB 3.0 Storage Enclosure

Your best bet is to pop it into another working mac from the same year group. I’ve done this plenty of times.
