I did the same with my 2015 MacBook Pro, and I'm still amazed that a $5 adapter and an Intel SSD are super fast and don't cause any problems at all. The machine sleeps, wakes, hibernates without any issues whatsoever. Also, I sold the original, well used Apple 1TB SSD for more than I paid for the brand new 2TB Intel SSD.
