Delivering PCIe® 5.0 speed to the mainstream segment, the KIOXIA BG8 Series combines next-generation capability with efficient operation and broad design flexibility for slim laptops, commercial and consumer notebooks, and desktop systems.

Built with KIOXIA’s BiCS FLASH™ generation 8 TLC-based 3D flash memory, the KIOXIA BG8 Series advances both performance and power efficiency¹. Compared to the previous generation, the KIOXIA BG8 Series achieves up to 47% higher sequential read, 67% higher sequential write, 44% higher random read, and 30% higher random write performance.

With sequential read speeds of up to 10,300 MB/s and sequential write speeds of up to 10,000 MB/s, along with random read and write performance reaching up to 1.4 million and 1.3 million IOPS respectively, the KIOXIA BG8 Series enables responsive system performance across a wide range of client workloads.

The DRAM-less KIOXIA BG8 Series supports a fully matured Host Memory Buffer (HMB) feature, leveraging host system memory to help balance performance, power consumption, and cost. Designed with flexibility in mind, the KIOXIA BG8 Series is available in multiple M.2 form factors – Type 2230, Type 2242, and Type 2280 – supporting a broad range of system designs and mounting requirements.

Key features include:

• PCIe^® 5.0 (Gen5 x4) and NVMe™ 2.0d compliant
• Self-Encrypting Drive (SED) support based on Trusted Computing Group (TCG^®) Opal version 2.02
• Capacities of 512 GB, 1024 GB, and 2048 GB
• Optimized for slim and mainstream client PCs

“Bringing PCIe 5.0 to the mainstream client segment is a key step forward for the industry,” said Maulik Sompura, director of product management, SSD business unit, KIOXIA America, Inc. “The KIOXIA BG8 Series delivers substantial performance improvements across both sequential and random workloads, giving OEMs the ability to design systems that are faster, more responsive, and better aligned with evolving user expectations.”

The KIOXIA BG8 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.

Notes:

¹ Compared to KIOXIA BiCS FLASH™ generation 5 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.

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.

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.

IOPS: Input Output Per Second (or the number of I/O operations per second).

NVMe is a registered or unregistered mark of NVM Express, Inc. in the United States and other countries.

PCIe is a registered trademark of PCI-SIG.
