Kioxia has released a next-generation solid state drive, the BG5, in a small form factor. The BG5 is a PCIe 4.0 SSD, and it may be suitable for certain upgrades, although its specific applications and performance are still being reported. The launch appears to be part of a broader effort to advance storage technology, with some outlets also mentioning a BG6 series, but details about the relationship between these products are unclear.
