Product Overview
The SK Hynix PS1101 is an ultra-high-capacity enterprise SSD purpose-built for AI and cloud data centers. Leveraging the industry's first 321-layer V9 Quad-Level Cell (QLC) NAND in an E3.L (EDSFF) form factor with a PCIe Gen5 NVMe interface, it delivers 245TB of storage density in a single drive — roughly 55% higher performance than SK hynix's previous 176-layer generation. Announced at FMS 2026, the PS1101 is engineered for maximum storage density and optimized for high-capacity workloads such as AI data lakes, object stores, and large-scale inference caching.
