Haven't bought a hard drive in years.
Don't intend to unless it's a seriously high-end thing for a server that has to be certified and firmware'd up, etc.
I see no reason that SSD/NVMe can't be your main product now and your sole product in years to come.
I'll do you a deal. Gimme a 1Tb SSD that's "only just" faster than an hard drive but comes with the tiny space, the no-moving-parts, non-hermetically-sealed boxes and the same price, and I'll buy dozens of them tomorrow.
Then you can slowly ramp the speeds back up to what they are now (i.e. Ludicrous Speed) and increase capacity as you go. Then in a few years time, I'll buy the same amount of 5Tb SSDs for the same price. And so on.
I honestly don't understand why HDDs even exist any more, or why companies that used to make HDDs are considered at all the people to get SSDs etc. from - entirely different technology and processes and they didn't see it coming and now they're reeling.
My Samsung 1Tb (which is stupendously expensive) has been in use for... 5 years straight. And it's still only £50 cheaper on Amazon than it was when I bought it.
I blame them focusing far too much on trying to justify their old business, and failing to get on board and ramp up SSD / Flash etc. It's like when I was watching Kodak produce printers and new cameras and films while everyone else was already using digital cameras.
