It depends a bit on whether reliability is better with the new design.
The older drives got hot and were quite noisy. That was a common complaint.
I guess WD found a way to improve those aspects and perhaps save money too with the “green”" drive.
It should really have had a different model number and specs.
From my point of view reliability is ahead of performance.
But to not inform ppl of the change was wrong. Ppl were buying for performance.
I would like to know if relaibility is better and by how much?
Also how does the power consumption/heat output compare?
