The SD Association has announced the microSD Express standard, which is part of the upcoming SD 7.1 specifications. The microSD Express standard uses one-channel PCIe 3.1 and NVMe 1.3 to achieve throughputs of up to 985 MB/s.
MicroSD Express has been developed due to the increasing demand of fast memory for applications like slow motion and 8K video and for 360 degree recordings.
The cards are backwards compatible and can lift on further developers of PCIe and NVMe. This means that future microSD Express cards could use, the for this year scheduled, fifth generation PCIe that allows throughputs of up to 4 GB/s
The new standard also ensures a decrease in latency and lower energy consumption.
