Their “Thunderblt certified” is not a Thunderbolt drive. It’s marketing nonsense for a USB 3,1 drive. Is it twice as fast as a USB 3 drive? Yes. Is it 1/3 the speed of their actual TB3 drive or a Samsung X5? also yes.

To answer your question, yes, it will do what you want but, being a USB 3.1 drive, it won’t be as fast as your Mac.

This
OWC TB3 drive
or a Samsung X5 is a true Thunderbolt 3 drive. The one you bought is not—it is less expensive.
