Kioxia Launches BG7 SSD with 8th-Gen 3D Flash

According to information released on January 7, Kioxia has officially unveiled its BG7 series SSDs, marking the industry's first consumer storage solution built on eighth-generation 3D flash memory. Designed with the company's CBA (Controller-BGA-Assembly) technology, the BG7 series targets both commercial systems and everyday PCs, aiming to deliver strong performance in a compact and flexible form.

In terms of performance, the BG7 series shows clear generational gains. Random read and write speeds reach up to 1 million IOPS, while sequential read speeds peak at 7,000 MB/s. Compared with the previous generation, random performance improves by around 10%, sequential read speeds rise by 16%, and sequential write power efficiency increases significantly—by as much as 67%.

The BG7 series also brings several platform-level upgrades. It supports the NVMe™ 2.0d specification and introduces a Type 2242 form factor, expanding compatibility across a wider range of PC designs. The SSDs adopt a DRAM-less architecture and rely on HMB (Host Memory Buffer) technology to balance simplified hardware design with consistent performance. They are compliant with PCIe 4.0 and will be available in 256GB, 512GB, 1TB, and 2TB capacities.

Kioxia showcased the BG7 series at CES 2026, where selected PC makers have already begun sample evaluation. The company expects the product line to enter mass production and reach the market in the near term, positioning it as a next-generation option for client storage platforms.
