Not meaningless, Hitachi historically had lower AFR in all models, I do not know how it is now with WD buying them off.
Seagate has some 6TB models that where horrible.
WD Reds 8TB had period of high DOA and AFR, it’s a lot of factories and a lot of different parts and supply chain so it depends and I understand that.
The used HDD are a coin toss in the sense that it depends on how many hours the drive have, if it is still early in the bathtub, it amazing, I would guess DC’s throw them out when they reach an internal EOL date or ROI is no longer motivating.
Well they are not when some SNOs are making a profit.
No, neither is littleskunk.
I noticed, it’s fine 
I call that encouragment.
Again, in case you missed, go read above, @littleskunk said he was making a profit and probably payouts should be reduced.
Now you are telling me that is not happening by design.
Can we all just pick a lane and stay on it? Pretty please?!
And @littleskunk you liked his post, he is contradicting you on this point, please sort it out, I am grabbing popcorn.
