honestly though. I kinda dislike that a 40 or 50tb mechanical drive is even a thing. What we really need is larger, more affordable solid state drives. Mechanical drives have had their place, but their limits are fairly clear at this point. And your point about rebuilding an array makes that obvious. They are just too slow. This move by seagate to make ridiculously large mechanical drives, should not be the beginning, as this article suggests. It should really be the end.
They’re slow, but they’re WAY more robust than most SSDs - and in terms of $/TB, it’s not even close. Especially if you’re comparing to SLC enterprise-grade.
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.
