Samsung’s UFS card is 5 times faster than MicroSD

Jul 7, 2016 - 9:50pm AST

Samsung has announced the next generation of expandable storage cards called Universal Flash Storage (UFS).

Based on the JEDEC Universal Flash Storage (UFS) 1.0 Card Extension Standard, their new line of UFS card have read speeds five times faster than top of the line MicroSD cards currently available on the market. The card is capable of reading data at 530 megabytes per second (530 MB/s), which means a 5GB film can be downloaded from the card in just 10 seconds, as compared to 50 seconds from a UHS-1 card.

Sequential write speeds have also significantly increased, hitting 170MB/s, which is close to double that of today’s MicroSD alternatives.

These increased speeds means much better performance for those who pulls extremely large amounts of data from storage devices, especially those who view high quality movies and other videos.

The doubled writing speeds also opened up a whole new ball park for the photo and video industries, allowing for newer cameras to store more data in less time.

With these substantial performance improvements, the new 256GB UFS card significantly reduces multimedia data downloading time, photo thumbnail loading time and buffer clearing time in burst shooting mode, which, collectively, can be particularly beneficial to DSLR camera users. To shoot 24 large/extra fine JPEG photographs (1,120 megabyte (MB)-equivalent) continuously with a high-end DSLR camera, the 256GB UFS card takes less than seven seconds, compared to a UHS-1 microSD card which typically takes about 32 seconds, at 35MB/s.

The cards will be made available in 32, 64, 128, and 256GB formats, but it is unclear as to when they plan to launch these next-generation devices.


Given the differing design on the back, UFS cards won’t be backward compatible with today’s traditional devices. It’s pretty safe to say Samsung will launch these new cards along with their next line up of smartphones and cameras before other manufacturers.
