Kioxia introduces 245TB SSD, the globally acclaimed storage device with highest capacity - capable of holding 12,500 4K films
Kioxia, a leading manufacturer of memory and storage solutions, has made a significant stride in the world of data storage with the introduction of its latest Solid-State Drive (SSD) – the Kioxia L9. This new SSD boasts an impressive capacity of 245.76TB, making it the highest-capacity storage device available.
The Kioxia L9 is designed for large hyperscale data center companies, focusing on high-capacity, sequential data workloads rather than intense random write performance. It is based on an NVMe 2.0-compliant controller with a PCIe 5.0 x4 interface and Kioxia's BiCS8 2Tb 3D QLC NAND memory devices.
The L9 drives incorporate features to improve reliability and protect data, similar to the Kioxia LC9. These features include die-level recovery, parity-based error management, and safeguards against sudden power loss. The drives also support multiple encryption modes, including AES-256 encryption and algorithms prepared for post-quantum cryptography.
The L9 drives achieve up to 1.3 million IOPS for reads and 50,000 IOPS for writes for random operations. Sequential read speeds reach up to 12 GB/s, while write speeds are around 3 GB/s. The L9 drives will be offered in multiple form factors: 2.5-inch U.2 (up to 122.88TB), E3.S (up to 122.88TB), and E.3L (up to 245.76TB).
Kioxia has managed to cram 8TB of storage capacity into a single NAND package, a record that enables the construction of such a hefty SSD. This is achieved via CMOS Bonded to Array (CBA) technology that bonds the NAND control circuitry directly to the memory array wafer-level. To enable a 245.76TB capacity in an E3.L form-factor, Kioxia had to package 32 memory devices into a single chip (8TB of storage space) and then attach those chips to the controller.
The Kioxia L9 drives are currently being sampled to select partners and will be featured at the Future of Memory and Storage conference in August 2025. The exact release date and pricing of the Kioxia L9 drives have not been disclosed, as they will be sold primarily to large hyperscale data center companies, and exact quotes will depend on volumes and other factors.
The Kioxia L9 SSD is ideal for applications that benefit from maximum storage density, such as AI training and hyperscale workloads. Its high capacity and sequential throughput make it a perfect fit for data lake and generative AI workloads that favour massive storage and high sequential throughput over intensive random write performance.
The Kioxia L9 SSD, a product of data-and-cloud-computing technology, is designed for large-scale data storage in hyperscale data centers, focusing on high-capacity, sequential data workloads. This technology-driven storage solution boasts an impressive capacity of 245.76TB, making it the highest-capacity storage device available.
