Grab any SSD from a gaming PC, and you'll find that it has one of two types of NAND flash memory chips: TLC or QLC. While the former is faster and more robust, the latter offers considerably more storage, making it ideal for housing terabyte-hungry games. And if SK Hynix's developments with PLC chips come to fruition, we could see a return to sensible SSD prices.
PLC or Penta-Level Cell flash chips aren't a new thing, as Intel, Toshiba, and SK Hynix all started working on their development a little over six years ago. Up to now, it doesn't seem like much progress has been made, but as reported by Blocks and Files, it would appear that SK Hynix has perhaps unlocked the key to making them commercially viable.
