SSD Prices Might Drop If SK Hynix Can Hack NAND Cells Like This

SK Hynix is developing a split-cell approach to NAND flash memory that could disrupt the SSD market. By dividing Penta-Level Cell (PLC) memory cells into two halves, the company reduces the number of voltage levels required from 31 to 6 per half. This technique aims to balance the high storage density of PLC with the reliability and speed closer to Triple-Level Cell (TLC) technology.

Current Quad-Level Cell (QLC) NAND dominates gaming SSDs for capacity, but PLC could offer higher storage with lower long-term costs if commercialized. The split-cell method addresses the trade-off between storage density and voltage precision—fewer voltage levels per half-cell reduce error rates while maintaining higher bits per cell than TLC.

This could make 2TB+ SSDs more affordable for gamers, who currently face high prices for large-capacity drives.

The AI industry’s growing demand for flash storage may accelerate PLC adoption. As AI workloads require massive data throughput and storage, SK Hynix’s approach could see faster commercialization, indirectly benefiting gamers through economies of scale. However, no timeline for production or pricing details has been disclosed.
