The SD Association has announced a new microSD Express format at the MWC 2019, which will make the new microSD cards much more faster. The new cards will count on the way more faster PCIe and NVMe interfaces often used on modern SSDs to reach speeds of up to 985 megabytes per second.
The full-size SD Express cards were actually first announced several months ago that promised similar transfer speeds as part of the SD 7.0 specification. But, at MWC SD association announced the SD 7.1 specification which will now bring the same speeds to the smaller and more versatile microSD format.
For more information, Western Digital claims that their 1TB SanDisk microSD card is the fastest 1TB card in the world which tops off at just 160MB/s for reading data, and 90MB/s for writing it. The new Delkin Devices’ 128GB Prime card tops out at a maximum read speed of 300 MB/s.
But we have to wait till these specification built microSD cards comes out in the market for consumer uses.
