During MWC 2019, the SD Association announced the MicroSD Express – a new memory card format which guarantees insane transfer speeds.
Yesterday at MWC (formerly known as Mobile World Congress) in Barcelona, the SD Association unveiled a new memory card format that will enable future mobile devices to consume and create content at even faster speeds all whilst consuming less energy.
Just like SD Express, the latest cards will be dependant on PCIe and NVMe interfaces, respectively, which are found on the second row of pins. The PCIe and NVMe specifications will deliver super-fast maximum transfer speeds of up to 985 megabytes per second, all while enabling advanced memory access mechanism.
The cards will be available in a mix of capacities, including microSDHC Express, microSDXC Express and microSDUC Express.
Enabling a whole new gateway of opportunities for mobile devices, the President of the SD Association, Hiroyuki Sakamoto, has discussed that “microSD Express gives the mobile industry a compelling new choice to equip mobile devices with removable SSDs.”
Full-size SD Express cards with faster transfer speeds were actually first unveiled a few months ago by the SD Association. However, the news which dropped yesterday at MWC means that they are now bringing those similar fast speeds to the smaller microSD format. The micro SD Express cards will, however, still comprise of the microSD backwards compatibility feature for older devices, although at a slower speed.
Read and write speeds have continued to be a factor previously restricting expandable memory. However, with the new microSD Express format, speeds for transferring data will happen almost as quick as built-in memory that it could put expandable memory back on the map.
As expected, however, users will still have to wait for card manufacturers to start producing microSD cards with the new, high-speed specification. But still, it’s great to know a faster future seems closer than ever before.
