"This jump isn't a shot across the bow to hard disk drive manufacturers; it's a boot on the throat".
I disagree.
In fact, I am having a hard time thinking which kind of consumer could make use of such SSD, at these prices.
I just so happened to be looking for a 4-bay NAS for home storage, and for ~$1600 I can get 24TB in Raid5 configuration. All inclusive, and with a fairly decent NAS (Qnap TS451).
A 6TB consumer HDD sells for $160. So we're talking about nearly 10X lower cost for 50% more capacity. Yes, of course, the HDD is massively slower, but HDD are still way faster than anyone needs, for streaming videos. Which if you need 4~6TB, and you are a consumer, it is probably what you need the disk for.
So the advantages of this drives boil down to:
a) Single disk setup
b) Large storage on a laptop
Point a) is “convenient”, at best, but would anyone pay ~$1200 for such convenience? (With $300 you can get a 500GB SSD + 6TB HDD).
Point b) may make a difference … however, seeing how the few laptops that ship with SSD have options for 128GB or 256GB, the 4GB is really wishful thinking. And, again, this carries more than $1K premium. Not for everyone, that’s for sure.
IMHO, this is great technological advance, that goes in the right direction, but I see no practical use, and very little market, for it. Again, IMHO.
