SSD storage is set to use 1,000 layer memory chips by 2027, potentially offering 20 TB NVMe drives for under $300

and dig inside its chips, you'd see that the flash memory is made up of many layers, hundreds in some models. Memory chip giant Kioxia is aiming to scale this all the way up to 1,000 layers by 2027, paving the way for 20 TB SSDs that could sell for as little as $250.), Kioxia declared its lofty goals at this year's International Memory Workshop in Seoul.

But the demand for more storage is as voracious as ever and the competition between Kioxia, Samsung, Micron, and others is really fierce, especially now that China-based flash foundries have joined the market. The only way to stand out in such a crowd is to have bigger flash memory chips that are fast and affordable.

However, it's not a simple case of just bonding more layers to make a Jenga-like wobbling tower of NAND flash. Even just getting to 400 layers is a serious challenge for the industry but Kioxia is planning on making it even harder by also targeting a bit density of 100 Gb per square millimetre. We're currently around the 20 to 30 mark at the moment, and it was barely above one a decade ago, so perhaps it's not too big of a challenge after all.

It's been a frustrating 18 months since launch but we'll finally be getting PCIe 5 SSDs worth a damn this year
