Japan-based memory manufacturer KIOXIA has announced its next-generation SSD solution, targeting the needs of productive artificial intelligence systems. This new NVMe SSD, called the LC9 Series, is the highest-capacity PCIe 5.0-compatible SSD ever introduced, boasting capacities up to 245.76 TB. The product is attracting attention in the data center market not only for its storage capacity but also for its performance and integration capabilities.
KIOXIA Announces 250 TB SSD Model
The KIOXIA LC9 Series is built on 8th-generation BiCS FLASH and CBA technologies. It houses 32 3D QLC NAND memory chips, each with a capacity of 2 terabit. This architecture enables high-density data storage while prioritizing energy efficiency.

Featuring a PCIe Gen5 interface, the new model delivers sequential read speeds of up to 12,000 MB/s and write speeds of up to 3,000 MB/s. Random access speeds reach 1.3 million IOPS read and 50,000 IOPS write.
The product is available in both traditional 2.5-inch and EDSFF (Enterprise and Datacenter Standard Form Factor) E3.S variants. The E3.S version also offers various capacity options up to 122.88 TB. This flexibility allows the product to adapt to diverse infrastructure requirements.
The LC9 Series is specifically designed to meet the high data transfer speeds, latency optimization, and large capacity requirements of modern AI techniques such as large language models (LLM) and retrieval augmented generation (RAG).
Currently, the LC9 Series is available only in samples to select enterprise partners. There is no public release date for the product. The product will be launched at the Future of Memory and Storage conference in August 2025.
