New SD Express memory card standard announced


The SD Association has announced the SD Express, a new memory card standard that offers capacities up to 128TB with maximum data transfer rates of up to 985MB/s.

SD Express adds the PCIe and NVMeTM interfaces, which are known for high bandwidth and low latency storage.

The PCIe interface delivering a 985 megabytes per second (MB/s) maximum data transfer rate and the NVMe upper layer protocol enables advanced memory access mechanism, enabling a new world of opportunities for the popular SD memory card. In addition, the maximum storage capacity in SD memory cards grows from 2TB with SDXC to 128 TB with the new SD Ultra Capacity (SDUC) card. These innovations maintain the SDA’s commitment to backward compatibility and are part of the new SD 7.0 specification.

The SD Association says that the new SD Express standard is intended for users who need to move large amounts of data, such as super-slow motion video, raw format burst sequences, 8K video capture and playback, 360 videography and anything that requires speed.

SD Express will initially be offered on SDUC, SDXC and SDHC memory cards. Below is a short video explaining the new standard.
