The microSD cards we use for storage expansion are going to be much faster and more economical in terms of power consumption. The SD Association has announced MicroSD Express, the next-generation memory card storage standard for SSDs that relies on NVMe and PCIe technologies to provide faster data read and write speeds. MicroSD Express cards are claimed to provide data transfer speeds of up to 985MBps and will be available in three variants.
The SD Association originally announced the Express Standard for SD cards in June last year and announced that they would be available in storage capacity up to 128TB. The same storage technology has now come down to microSD cards which will soon be available in three versions – MicroSDHC Express, MicroSDXC Express and MicroSDUC Express. The new lineup of the Express series microSD card follows the SD 7.1 specification and will be available in multiple storage options.
MicroSD Express cards have a second row of pins that are used to animate PCIe 3.1 and NVMe 1.3 technology in such a small size factor. The SD Association claims that microSD Express cards are essentially the equivalent of removable SSD cards on smartphones and other compatible devices. In addition to significantly faster data transfer speeds, microSD Express video cards are also claimed to consume less power, as well as being an ideal solution for high-intensity work such as capturing super slow motion video, RAW burst mode output and 8K video playback.
In addition to regular users and professionals, microSD Express memory cards are claimed to bring more versatility and new solutions for developers such as bus mastering, multi queue and host memory buffers. In addition, the new generation of faster microSD cards comes with features like advanced data processing and an improved memory access mechanism. In addition, like the previous iteration of the microSD card, the Express line-up retains backwards compatibility features in addition to password lock protection and data writing protection.
It will take a while for these to become available to consumers as card makers will have to use standard and create new cards and laptop / camera / mobile phone companies will have to create new hardware that is actually capable of taking advantage of these. Speed
