Samsung Electronics has unveiled removable memory cards based on the JEDEC Universal Flash Storage (UFS) 1.0 Card Extension Standard for use in high-resolution mobile shooting devices such as DSLRs, 3D VR cameras, action cams and drones.
Samsung's UFS cards come in storage capacities of 256, 128, 64 and 32 GB.
The new 256GB UFS removable memory card provides more than five times faster sequential read performance compared to that of a typical microSD card, reading sequentially at 530MB/s which is similar to the sequential read speed of the most widely used SATA SSDs. 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. 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.
When it comes to writing, the new 256GB UFS card processes 35,000 random IOPS, which is 350 times higher than the 100 IOPs of a typical microSD card, and attains a 170MB/s sequential write speed, almost doubling the top-end microSD card speed.
To shoot 24 large/extra fine JPEG photographs (1,120MB-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.
