SD Express memory cards expand interfaces to PCIe and NVMe

When the SD Association (SDA) first announced SD Express in June 2018, it set the bar high and opened a world of possibilities for manufacturers to integrate supercharged removable storage into their designs. SD Express is capable of delivering SSD performance levels of up to 4GB/sec.

This makes it perfect for use in high-performance electronic devices and products. With the introduction of advanced security features in May 2022 found in the SD specification version 9, performance and versatility merge to create an innovative, and advanced powerhouse solution for SD memory cards.

SD Express leverages the PCI Express and NVMe interfaces and uses the well-known SD memory card form factor for compatibility with existing SD slot architectures. The SDA also introduced a microSD Express memory card format that is backward compatible with devices. SD Express is not just about SD memory cards getting faster, it is also about SD memory cards doing more.

This type of memory card could be used, with a suitable interface, with the Raspberry Pi 5 and its PCIe bus expansion capability.
