Yes (in the US and Canada).

I think the system will accept them, but that the performance will be worse than with CMR drives. How much worse is hard to say. You can read through the arstechnical tests earlier, they are probably closer to what you'll see in legacy ReadyNAS than the servethehome tests.
One option would be to go with jbod (one volume per disk), and not use RAID.

Hi Stephen and Sandshark
Thanks for your input to this discussion, which has help me to make up my mind towards future HD purchases.
It now seems the best way to go is to purchase WD Red Plus in the future, the prices of the Red Plus drives are still within the bounds of being affordable and as long as they maintain their reliability I will continue to buy them as and when needed.
So my next planned purchase will be 2 x 3TB WD Red Plus HDs, hopefully in the new year.
Thanks for your help and advice.
And guys, have a merry Christmas and a happy (better than 2020) new year.
