How to Implement SD Express into Your Products

Learn about the capabilities of SD Express, and see how SD Express storage works in devices. Standard off-the-shelf solutions and several initialization options give SD Express cards huge advantages. Plus, the interoperability of these cards provides access to the huge number of SD products available today. SD Express meets users’ demanding storage needs and delivers faster transfer speeds by incorporating PCIe® and NVMe™ capabilities alongside the SD interface. This opens new opportunities for applications to use the highest-performance removable memory cards. SD Express achieves speeds of up to ~1GB/s (985 MB/s) with PCIe 3.1 x1 (single lane) and up to ~4GB/s (3938 MB/s), with PCIe 4.0 x2 (dual lane). These speeds support content applications and data generated by highly demanding system architectures. SD Express memory cards can serve as removable Solid State Drives (SSD). PCIe and NVMe are known worldwide for their high bandwidth and low latency storage capabilities. In anticipatio
