TOKYO, August 26, 2025 – Kioxia Corporation, a world leader in memory solutions, today announced high-capacity, high-efficiency data storage solutions designed to support AI-scale workloads and reduce power and cooling requirements with Dell Technologies. Leveraging KIOXIA LC9 Series 245.76 terabyte (TB) NVMe™ SSDs, Dell systems enable organizations to manage multi-petabyte data sets and modernize their infrastructure to support generative AI and machine learning applications.

KIOXIA LC9 Series SSDs, unveiled in July, deliver up to 245.76 TB of flash-based storage with PCIe® 5.0 performance in high-density and better utilize GPUs. This results in a more efficient use of space and power, enabling organizations to scale AI infrastructure without expanding their physical footprint or energy consumption.

“Together, Dell Technologies and Kioxia have a long history of enabling scalable infrastructure for data-driven applications,” said Arun Narayanan, senior vice president, Compute and Networking, Dell Technologies. “SSDs like the KIOXIA LC9 Series combined with Dell PowerEdge servers offer high-capacity, power-efficient solutions tailored for advanced AI workloads while optimizing TCO and data center footprints.”

Built with BiCS FLASH™ generation 8 3D flash memory using 32-die QLC stacking and innovative CBA (CMOS directly Bonded to Array) technology, the KIOXIA LC9 Series enables compact, large-capacity SSDs ideal for the demands of AI infrastructure—from training large language models (LLMs) to powering inference pipelines like retrieval augmented generation (RAG).

“Enterprises today are pushing the limits of their data center infrastructure to stay competitive in the AI era,” said Masashi Yokotsuka, Vice President of the SSD Division at Kioxia Corporation. “With our KIOXIA LC9 Series SSDs, together with Dell Technologies we’re removing storage bottlenecks, driving higher rack-density and enabling more sustainable, scalable systems that make the most of every GPU and each watt of power.”

This continued collaboration builds on more than two decades of innovation between Kioxia and Dell Technologies. Together, the companies have delivered storage industry milestones, including the first enterprise deployments of PCIe 5.0 EDSFF E3.S(1), 24G SAS(2), and Value SAS(3) technologies.

  • Definition of SSD capacity: Kioxia Corporation defines a kilobyte (KB) as 1,000 bytes, a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes, a terabyte (TB) as 1,000,000,000,000 bytes, and a kibibyte (KiB) is 1,024 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 2^30 bytes = 1,073,741,824 bytes and 1TB = 2^40 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
  • The flash memory capacity is calculated as 1 terabit (1 Tb) = 1,099,511,627,776 (2^40) bits, and 1 terabyte (1 TB) = 1,099,511,627,776 (2^40) bytes.
  • Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.
