Samsung is the first to offer a taste of the next-gen memory cards. Its new Universal Flash Storage cards are the same size as microSDs, but can match the blazingly-fast data transfer speeds of solid state drives.
The new cards are based on the new JEDEC Universal Flash Storage 1.0 Card Extension Standard, which is aimed at upping data transfer speeds, as well as ending the need for different card type adapters.
Samsung is claiming a sequential read speed of 530 megabytes per second, which is up to 5 times faster than a typical microSD card, and in a similar league to SATA SSDs. The result? Samsung says its latest storage options mean it would take about 10 seconds to read a 5 GB high definition movie, as opposed to 50 seconds for a UHS-1 microSD card with a 95 MB/s sequential read speed.
The 256 GB UFS card works at a rate of 40,000 IOPS, an improvement of more than 20 times compared to a typical microSD card’s random read rate of 1,800 IOPS. Write speed is also up dramatically, with Samsung promising 35,000 random IOPS from its 256 GB card.
For fast and efficient data transfer, the card supports multiple commands and command queuing, while separately dedicated paths allow concurrent reading and writing.
As the pin configuration on the back of the cards is different to microSD, the move to UFS may not be a perfectly smooth one.
