About This Product
The Kioxia BG4 is a compact M.2 2230 NVMe SSD utilizing PCIe 3.0 x4. With 128GB capacity, it offers significantly faster performance than SATA SSDs, but its small capacity limits its use as a primary drive for modern operating systems and games. It is best suited for embedded systems, single-application devices, or as a cache drive where space is at a premium.
Verdict
βIdeal for embedded systems or as a secondary cache drive where space is critical.β
