KIOXIA Corporation has developed the KIOXIA GP1 series of Super High IOPS SSDs, which enable direct GPU access and high-speed random reads of up to 10 million IOPS (Note 1) for AI applications. Supporting PCIe® 6.0 and NVMe™ and utilizing second-generation KIOXIA XL-FLASH™ flash memory, the KIOXIA GP1 series is the first product in the KIOXIA GP series ( Note 2) , which was announced in March 2026. By enabling flash memory-based memory expansion, it contributes to meeting the increasing performance and memory demands in AI infrastructure. Evaluation samples of this product will begin shipping to select customers by the end of 2026 ( Note 3) , and will be exhibited at FMS: The Future of Memory and Storage, held in Santa Clara, California, USA, from August 4 to 6, 2026.
The KIOXIA GP1 series supports a new AI storage architecture that extends high-bandwidth memory (HBM) as a high-speed flash memory-based tier, enabling AI systems to access larger datasets at a significantly lower cost compared to adding HBM ( Note 4) , and also contributing to improved GPU utilization efficiency.
The KIOXIA GP1 series Super High IOPS SSDs, which utilize low-latency, high-performance second-generation KIOXIA XL-FLASH flash memory, achieve significantly higher IOPS performance ( Note 4) , access in granular data units of 512 bytes, and low power consumption per I/O compared to conventional TLC-based SSDs. This architecture is designed with future expansion in mind, aiming for a maximum of 100 million IOPS from the current 10 million random read IOPS.
Key features of the KIOXIA GP1 series
- Supports PCIe® 6.0 and NVMe™ 2.2 standards.
- It employs second-generation KIOXIA XL-FLASH™ low-latency flash memory.
- Maximum 10 million random read IOPS in 512-byte units (Note 2)
- The lineup includes E3.S and E1.S 9.5 mm / 15 mm form factors. The E3.S and E1.S 9.5 mm form factors support both air cooling and liquid cooling (all form factors support conventional air cooling environments).
- High durability with a maximum of 50 DWPD (Note 5)
Note 1 Read and write speeds vary depending on the host system, read/write conditions, file size, etc.

Note 4 As of July 28, 2026, according to Kioxia.
Note 5 DWPD: Drive Writes Per Day. This value is calculated by dividing the total write capacity (TBW) by the drive user capacity (TB) and the number of days of rated life. It indicates how many units of drive capacity need to be written per day on average to reach the total write capacity (TBW) when the rated life is reached.
*Storage capacity: These values are calculated using the following formulas: 1 MB (1 megabyte) = 1,000,000 (10 to the power of 6) bytes, 1 GB (1 gigabyte) = 1,000,000,000 (10 to the power of 9) bytes, and 1 TB (1 terabyte) = 1,000,000,000,000 (10 to the power of 12) bytes. However, computer operating systems that use 1 GB = 1,073,741,824 (2 to the power of 30) bytes and 1 TB = 1,099,511,627,776 (2 to the power of 40) bytes as drive capacity will display a smaller capacity than indicated. Drive capacity varies depending on file size, format, settings, software, operating system, and other factors.
