Demand might be low, but on the other hand the cost to develop and manufacture a run of the drives may not be too high either.
I do have to say the increase in flash memory prices haven’t helped. A year ago I bought the Samsung 8TB drive for $300 (US). If they had a 16TB model for $600-$700 I would have bought it.
What they need to do is take that mostly empty 2.5" drive, and cram it full of flash chips. Why have we been stuck with 8TB as the largest consumer drives for a few years now? I can understand it a bit for NVMe due to the physical form factor, but there’s no excuse for 2.5" drives. It doesn’t seem that complicated. For example, all Samsung would have to do is take the 2.5" 8TB 870 QVO, double the number of chips in it, then sell it for twice the price. I’d buy one.
