White Paper SD Express
In June 2018, the SD Association, responsible for setting SD memory card standards, released a specification for SD Express memory cards for the first time. This specification enables the cards to achieve data transfer speeds of nearly four gigabytes per second. This performance boost is made possible by incorporating PCIe 4.0 and NVMe interfaces, commonly found in solid-state drives.
The introduction of this new SD card variant signals an upcoming competitive showdown between the established standard and its successor. This white paper aims to provide an unbiased comparison between the two SD representatives and offer valuable decision support.
