I’ve definitely seen more hdd failures than ssd failures in my life, that said, enterprise storage is indeed very robust. My WD red pros have all been workhorses. And right now the price per dollar is definitely in favor of HDDs. That really needs to change though. The raw materials alone make HDDs more expensive to produce, the problem is only that there are less manufacturers with the means to actually produce the chips necessary for SSDs because HDDs have been around for a million years. Once that changes, I think HDDs will and should go the way of every obsolete storage medium thats existed prior.
