Kioxia Unveils High Performance XG10 Series SSDs for PC OEMs

SAN JOSE, Calif., May 13, 2026 – KIOXIA America, Inc. today announced the KIOXIA XG10 Series solid-state drives (SSDs), its latest high-performance client storage solution engineered for PC OEMs. Targeting the performance segment, the new KIOXIA XG10 Series leverages PCIe^® 5.0 technology to significantly elevate speed and responsiveness across data-intensive client applications.

Designed as the successor to the KIOXIA XG8 Series, the KIOXIA XG10 Series adopts a PCIe 5.0 interface, enabling improvements in both sequential and random performance. Compared to the previous generation¹, the new drives achieve up to 2x sequential read, more than 2x sequential write, and increases of approximately 122% in random read and 158% in random write performance - supporting faster data access and improved system responsiveness.

The KIOXIA XG10 Series is engineered to meet the needs of high-performance client system environments. These include professional applications, private AI training and inference, content creation and editing workflows, and immersive gaming experiences. With sequential read speeds of up to 14,000 MB/s and sequential write speeds reaching up to 12,000 MB/s, along with random read performance of up to 2,000 KIOPS and random write performance up to 1,600 KIOPS, the KIOXIA XG10 Series enables high-throughput performance for modern computing demands.

Additional features include:

• PCIe^® 5.0 (Gen5 x4) and NVMe™ 2.0d compliant
• Self-Encrypting Drive (SED) support based on TCG Opal
• Recommended for high-performance PC systems including AI PCs, workstations and gaming platforms
• M.2 Type 2280 form factor
• Capacities of 512 GB, 1024 GB, 2048 GB, and 4096 GB

“PCIe 5.0 represents a major step forward for client storage, particularly in the performance segment,” said Maulik Sompura, senior staff director, product management, SSD business unit at KIOXIA America, Inc. “With the KIOXIA XG10 Series, we are delivering significantly enhanced performance that improves the overall client storage experience for content creators, gamers, and professionals working with increasingly demanding workloads.”

The KIOXIA XG10 Series is currently sampling to select PC OEM customers, with PC shipments equipped with the SSD expected to begin from the second quarter of 2026. The new drives will be showcased at Dell Technologies World, taking place May 18 – 21 in Las Vegas.

Notes:

¹ Compared to KIOXIA XG8 Series SSDs.

² Developed by the Trusted Computing Group® (TCG), a not-for-profit international standards organization, the Opal specification is used for applying hardware-based encryption to solid state drives and is often referred to as TCG-Opal.

³KIOXIA XG10 Series 512 GB, 1024 GB models utilize BiCS FLASH™ generation 6 TLC-based flash memory, 2048 GB, 4096 GB models utilize BiCS FLASH™ generation 8 TLC-based flash memory.

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.

Read and write speed may vary depending on the host device, read and write conditions, and file size.

Availability of the SED model line-up may vary by region.
