SanDisk Unveils 1PB SSD Roadmap and 3D DRAM Challenges

At its Investor Day, SanDisk revealed its roadmap for 1PB solid-state drives based on its UltraQLC technology, alongside insights into the challenges of 3D DRAM. UltraQLC combines BICS 8 QLC 3D NAND, a 64-channel controller, and custom firmware for high density, performance, and efficiency. While 1PB SSDs are on the horizon, 3D DRAM faces significant hurdles. SanDisk is exploring alternatives like High Bandwidth Flash (HBF) to address the massive memory demands of AI training.
