Microsd express will offer up to 985mb / s on a sd memory card

SD Association has unveiled its MicroSD Express standard, updating the 'humble' SD cards with PCIe and NVMe connectivity. In summary, the performance of SSDs with NVMe interface is reaching the world of MicroSD cards, while offering compatibility with older standards such as SD and SD-UHS104.

MicroSD Express, PCIe / NVMe interface reaches SD cards

What changes with MicroSD Express is that the second row of pins on UHS-II cards are reused to support PCIe 3.0 x1 connections, and the new standard uses the NVMe protocol to offer transfer speeds of up to 985 MB / s. This change will allow future SD cards to provide transfer speeds that exceed SATA solid state drives, which is an astonishing feat given the small form factor of MicroSD cards that we have today.

This will also break backward compatibility with UHS-II and UHS-III devices, although UHS speeds of up to 104MB / s can still be used. With MicroSD Express, speeds of up to 985 MB / s are possible, which is great news for future high-performance mobile devices.

Comparison chart

NMVe 1.3 compatibility also adds several specifications similar to SSDs, such as bus mastering, multi-queuing, host memory buffering, and various other enhancements, while maintaining compatibility with SD UHS104 and other standards..

Speeds of 985 MB / s create a mini-revolution within devices that use microSD cards, such as mobile phones and tablets. In a short time we will be able to see portable devices with expanded capacity that read and write data faster than a desktop computer with a hard disk and even with SATA SSDs.
