As I've said above, "Exactly what I want and exactly as described". A very good price. Took less than the predicted time to arrive.
A suggestion for Western Digital. Supply two leads! The drive came with, USB C to USB C, plus USB A adaptor. It would have been nice to have a USB C to USB A lead. I've misplaced the adaptor on a number of occasions. And, although the adaptor is not too expensive, if you find yourself without one it can be annoying as you might understand. Even as an extra-cost option, it would be nice.
With that winge, out of the way, the purchase was, to quote DT, "Perfect"!
