The Kioxia BG7 is a solid-state drive in the M.2 2230 form factor, launched on January 5th, 2026. It is available in capacities ranging from 512 GB to 2 TB. This page reports specifications for the 512 GB variant. With the rest of the system, the Kioxia BG7 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the SM2268XT2 from Silicon Motion, a DRAM cache is not available. Kioxia has installed 218-layer QLC NAND flash on the BG7, the flash chips are made by Kioxia. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The BG7 is rated for sequential read speeds of up to 6,400 MB/s and 5,500 MB/s write; random IO reaches 550K IOPS for read and 850K for writes.
