Samsung today showed off its successor to the microSD card, the UFS – that’s Universal Flash Storage. And the specs on the removable storage look pretty impressive at first glance. With capacities running 32- to 256GB, the slim little cards are focused on the increased storage/bandwidth needs of high-res capture devices like DSLRs, VR cameras and the like.
Along with the storage bump (though, for the record, the company also showed off a 256GB microSD card back in May), the cards boast some crazy fast read and write times. Read speeds peak out around 530 megabytes per second, which put it at around five times the speed of high-end microSDs.
The cards offer “more than five times faster sequential read performance compared to that of a typical microSD card,” as they’re able to read sequentially at 530 MB/s, which is on par with SSD sequential read speeds.
“With this UFS card, consumers have the ability to read a 5GB, Full-HD movie in approximately 10 seconds, compared to a typical UHS-1 microSD card, which would take over 50 seconds with 95MB/s of sequential reading speed,” Samsung writes. “Also, at a random read rate of 40,000 IOPS, the 256GB card delivers more than 20 times higher random read performance compared to a typical microSD, which offers approximately 1,800 IOPS.”
UFS cards will read a 5GB Full HD movie in 10 seconds, compared to 50 seconds for a microSD card that can do up to 95MB/s sequential reading.
As for write speeds, the 256GB UFS card reaches a top speed of 170MB/s, or almost twice the speeds the fastest microSD card can achieve. “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,” Samsung explains.
Samsung’s been working on the format for some time now – in fact, the company already embedded it into some existing mobile devices, but this is the first time it’s showing off the expandable storage version of the cards. Which means, among other things, that you’ll be hard pressed to find any devices that actually read the new format.
Though, with all of the talk around a forthcoming Galaxy Note 7 release, that may change sooner than later.
