Silicon Motion Launches PCIe 4.0 NVMe SSD Controllers
 

Silicon Motion has announced the official launch of their first generation of PCIe 4.0-capable NVMe SSD controllers. These controllers have been on the roadmap for quite a while and have been previewed at trade shows, but the first models are now shipping. The high-end SM2264 and mainstream SM2267/SM2267XT controllers will enable consumer SSDs that move beyond the performance limits of the PCIe 3.0 x4 interface that has been the standard for almost all previous consumer NVMe SSDs.
