So, I can understand your frustration but, 4 discs out of how many thousands they make

Um, I don't think there is anyone doing this as standard practise in industry.
Typically data centres buy systems from Dell and the like and they
provide the drives, which are always from the same model in one system.
Maybe in hand built lab machines you'd do this, but that is for someone
repurposing old hardware or some specialized purpose, not standard
computing production platform.
In my lab, we used several WD15EARS-32M (WD Green 1.5TB) and a few died early, as well as other HD from other brands. So, really I think the issue is almost of the time a batch issue than a brand or design issue.
Maybe these WD HD have design issues, but for sure the experience depicted here is not really conclusive.
If Western Digital themselves are telling us not to use green drives in RAID 1
doesn't this mean something? It isn't really a "design issue", but more
of an engineering purpose. You don't put a fridge on the trunk of a VW Jetta,
you get a van or truck for this purpose. Similarly you don't use a green drive,
engineered for desktop users with lots of downtime (typical green drive
user: check mail, make toast, check the web for news, make coffee,
answer a phone call, answer email - lots of spurts of minor activity with sleep
cycles between) and purpose this for a server or other purposes running
the hard drive hard. Its like anything else... There are washing machines
for home and commercial use - if you use the home version in commercial
use it will destroy itself. Likewise with printers, copiers, etc. - a $40 consumer
printer is not designed to print off large documents in an office setting.
