FMS 2026: Kioxia Announces Kioxia GP1 Series Super High IOPS SSDs for AI Applications

Kioxia Corp. announced the Kioxia GP1 Series PCIe 6.0 NVMe SSDs, the first product in its Kioxia GP Series of Super High IOPS SSDs optimized for GPU direct access.Building on the Kioxia GP Series technology introduced earlier this year¹, the Kioxia GP1 Series delivers up to 10 million random read IOPS² using Kioxia XL-FLASH generation 2 flash memory, enabling flash-based memory extension to help address the growing performance and memory demands of AI infrastructure. Evaluation samples will be available to select customers by the end of 2026³. The Kioxia GP1 Series will be showcased at FMS: the Future of Memory and Storage, taking place August 4 – 6 in Santa Clara, CA.

The Kioxia GP1 Series is designed to support emerging AI storage architectures, which extend HBM as a fast flash memory media-based tier. This approach lets AI systems access larger datasets at a significantly lower cost than adding more HBM⁴, while improving GPU utilization.

Kioxia GP1 Series SSDs leverage Kioxia XL-FLASH generation 2 low-latency, high-performance flash memory to deliver significantly higher IOPS⁴, finer-grained 512-byte data access, and lower power consumption per I/O compared to conventional TLC-based SSDs. The architecture is designed to scale from today’s 10 million random read IOPS to future generations targeting up to 100 million IOPS.

Key features of the Kioxia GP1 Series include:

Designed to PCIe 6.0 and NVMe 2.2 specifications
Utilizes Kioxia XL-FLASH generation 2 low-latency flash memory
Up to 10 million random read IOPS at a 512-byte block size²
Available in E3.S, E1.S 9.5 mm/15mm form factors, with cold-plate liquid cooling capability in E3.S and E1.S 9.5mm form factors (all form factors support traditional air-cooled environments)
Up to 50 DWPD endurance⁵

Notes:

1: Kioxia Announces New SSD Model Optimized for AI GPU-Initiated Workloads (https://www.kioxia.com/en-jp/business/news/2026/20260317-1.html)
2: Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions
3: These samples are for the functional check purpose only and the specifications of the samples may differ in mass production
4: As of July 28, 2026, based on Kioxia survey
5: DWPD: Drive Writes Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day under the specified workload for the specified lifetime. Actual results may vary due to system configuration, usage and other factors
