Kioxia Corporation Expands High-Capacity Enterprise SSD Lineup

Kioxia Corporation has broadened its range of high-capacity KIOXIA LC9 Series enterprise SSDs by introducing the industry's first 245.76 terabyte (TB) NVMe SSD in 2.5-inch and EDSFF E3.L form factor. This new capacity and form factor option complements the previously announced 122.88 TB (2.5-inch) model and is specifically designed for the performance and efficiency requirements of generative AI environments.

Unique Demands of Generative AI

Generative AI presents distinct challenges for storage, such as the need to store vast datasets for training large language models (LLMs) and creating embeddings and vector databases to support inference through retrieval augmented generation (RAG). These tasks demand storage solutions with exceptional capacity, speed, and efficiency.

Advanced Technology

The KIOXIA LC9 Series SSDs feature a 32-die stack of 2 terabit (Tb) BiCS FLASH QLC 3D flash memory with innovative CBA (CMOS directly Bonded to Array) technology. This advanced memory architecture and CBA technology enable an 8 TB per small 154 BGA package, a first in the industry.

Benefits of KIOXIA LC9 Series SSDs

The KIOXIA LC9 Series SSDs are ideal for data lakes, offering dense storage in a compact footprint with greater capacity per watt. With up to 245.76 TB capacity, they can replace multiple power-hungry HDDs, providing superior performance, lower power consumption, and more efficient cooling.

Features of KIOXIA LC9 Series SSDs

  • Up to 245.76 TB SSD in 2.5-inch and E3.L form factors
  • Up to 122.88 TB available in E3.S form factor
  • Designed to PCIe 5.0 (max. 128 GT/s Gen 5 single x4, dual x2)
  • NVMe 2.0, NVMe-MI 1.2c specifications
  • Open Compute Project (OCP) Datacenter NVMe SSD specification v2.5 support (not all requirements)
  • Flexible Data Placement (FDP) support to minimize write amplification and extend SSD lifespan
  • Security options: SIE, SED, FIPS SEDCNSA 2.0 signing algorithm adopt, designed with future quantum security standards in mind

KIOXIA LC9 Series SSDs are currently available for sampling to select customers and will be showcased at the Future of Memory and Storage 2025 conference, happening on August 5-7 in Santa Clara.
