Western Digital Teases 128 TB Enterprise SSD: BiCS8 3D QLC for AI Workloads
by Ganesh T S & Anton Shilov on August 7, 2024 11:00 AM EST A week after Western Digital confirmed that it had begun sampling of its 64 TB SSDs for datacenters, the company has teased its next-generation product, a 128 TB solid-state drive at FMS 2024. For now, all we know about Western Digital's 128 TB SSD is that it uses the company's BiCS8 QLC NAND memory and is designed primarily for 'fast AI data lakes and capacity-intensive performance applications,' as Western Digital does not seem to be disclosing too much information about its upcoming product.
It must be noted that this technique is an evolutionary successor to Micron's CMOS-under-Array (CuA) and SK hynix's Periphery-under-Cell (4D PUC) technologies. Samsung recently said that it has technology to build 120 TB-class drives, and Solidigm was also demonstrating a proof-of-concept 122 TB QLC SSD at FMS 2024. This has served as an impetus for enterprise SSD vendors to continue pushing the envelop on the per-drive capacity front.
