Keep in mind data recovery vs drive size. Getting past ~16TB drives, it starts to become a question of whether the rest would be able to survive a restore of a failed drive if any are going to have remotely similar endurance. Obviously, the answer is going to be "yes" most of the time, but at a certain point, there are deminishing returns on the cost of the drives to where even a one to one price increase in the HDD per size might not be worth it all the same.
Kinda' a moot point if you're not going to raid them in any way for reliability, but worth a thought.
I've described this terribly, but Level1tech on YT talks about it sometimes in reviews.
