As far as speed, it's not like they can do much on that front. They've already hit the limit of the SATA bus more than 5 years ago.

I agree with pricing. At current densities, it's possible to fit 16+TB on the current 2.5" form factor. It's just going to be prohibitively expensive at the moment even with QLC. I doubt demand is currently there for such drives (at least on the consumer end). Hopefully though, QLC pricing goes down eventually as it did with TLC/3D TLC. Maybe when they start using more NAND packages (ergo more parallelism) to get to higher capacities, we'll see QLC-based SSDs saturating SATA for sustained sequential writes again. Sure would be nice to get an 8TB SSD for under $500.

The SATA standard is what it is though and it's not gonna exceed PCIe ever.
