4 Gb/mm² for HDD density is a lot. For comparison: 7 Gb/mm2 - current NAND technology 0.3 Gb/mm² - current DRAM technology 0.2 GTr/mm² - current FinFET tech

- dogma1138 6y agoPure density isn’t everything, magnetic storage doesn’t have the same power and heat increases with storage density as solid state semiconductor storage has.

- AtlasBarfed 6y agoI didn't know NAND was that dense, is that for QLC 100+ layer? At this point it comes down to the expense of stamping out the NAND chips in order for SSD to pass HDDs in cost.

Good lord, Micron shipped 176 layer QLC/TLC compatible chips.
