OLC NAND... every cell row needs a 10+bits low-noise ADC to sense cell charge with enough resolution to statistically resolve intermediate states based on how surrounding cells have drifted away from nominal values. This is basically going to be SMR for NAND.

Some manufacturer could probably come out with a 1 PB SSD in a larger form factor like 3.5" or a PCIe AIC using today's NAND. But there's no market for it. The cost reduction from cheaper NAND will be more important than density increases.

Hopefully PLC/HLC/OLC aren't complete crap, after new technologies are invented just to make them feasible.

Samsung, where is your ssd > 2 tb ? nowhere...

The cost reduction from cheaper NAND will be more important than density increases.

NAND cost reduction usually goes hand-in-hand with bit density increases though, be it by increased layer counts or extra bits per cell.

Samsung: 10 years from now, 1PB SSDs!
Samsung: Today, 2TB NVMe SSD, $230
Samsung: In 2015 we launched the Samsung 850 Pro for $999

Something tells me a 1PB drive will not cost less than six figures at launch

If we look at enterprise-grade stuff, 64TB SSDs are around 11k$ each and 16 of those to make 1PB is 176k$ not counting the server you'd need to stuff all of those in. You only need to halve the cost per bit once to get under 100k$ and the cost per bit will certainly get halved more than once before any single SSD gets to 1PB.

If you use consumer SSDs as a reference, 2TB is ~$160 and 500 of those to make 1PB is only 80k$. If we had straight up density increases with no cost-per-bit improvements, we are already set to hit 1PB under 100k$.
