NVMe for all I care
GOTTA GO FAST!
That's a good point. However, SSD's have one glaring problem; price. To get the same capacity from an SSD that you would get from a HDD, you'll easily spend ten times the money, or more. For example, one of my drives is a Seagate 8TB model. I paid right around $190 at the time of purchase. Pricing out an 8TB SSD? Oh, wait there aren't any on consumer levels. And enterprise drives are literally above $3000. The closest you can currently get is 2TB at around $500.
So for the time being, HDD's are still the way to go if you need any decent capacity for reasonable prices. So finding new ways to make HDD's work better/faster is still a very much welcome and needed advancement.
