After Western Digital announced its 2Tb 3D QLC NAND components in mid-June, it was a matter of time before its manufacturing partner Kioxia followed suit and revealed its 2Tb 3D QLC devices, which it did today. Unlike Western Digital, Kioxia shared more details about these 256GB 3D QLC NAND components, which look like they can be used to build high-performance and high-capacity drives.
Kioxia's 2Tb 3D QLC NAND devices rely on the company's 218-layer BiCS8 process technology and boast an interface speed of 3,600 MT/s, making them some of the world's fastest flash memory components. In addition to increased performance, the new devices boast a 70% write power efficiency compared to Kioxia's 3D QLC based on the BiCS5 production node (due to higher density and power efficiency).
