Launching in 2026: The KIOXIA LC9 Series 245.76TB NVMe™ SSD — the highest-capacity PCIe® 5.0 enterprise SSD — will be available from Bytehaus. Built for Generative AI, HPC, and large-scale enterprise storage, it delivers unprecedented density, performance and efficiency.
Why the KIOXIA 245TB NVMe SSD matters
- Unmatched capacity: Up to 245.76TB per drive (2.5-inch & EDSFF E3.L)
- PCIe Gen5 performance: Ultra-low latency and very high throughput to keep GPUs fully utilised
- Lower power per TB: Reduce rack power and cooling while increasing storage density
- Space efficiency: Consolidate racks of HDDs into a compact, high-density footprint
Built for the AI era
From training large language models (LLMs) to powering retrieval-augmented generation (RAG) and managing vast vector databases, AI workloads demand extreme storage performance and scale. The LC9 Series combines 32-die stack BiCS FLASH™ QLC 3D flash with CBA (CMOS directly Bonded to Array) technology, enabling an industry-first 8TB per 154 BGA package. Flexible Data Placement (FDP) support helps minimise write amplification to extend service life.
