Samsung's UFS: The World’s First Universal Flash Storage (UFS) Removable Memory Card
What is better than a 256GB memory cards, well how about a 256GB memory cards with ridiculously fast transfer speeds! The Universal Flash Storage (UFS) card provides more than five times faster sequential read performance compared to that of a typical microSD card, reading sequentially at 530 megabytes per second (MB/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. 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.
To achieve the highest performance and most power-efficient data transport, the UFS card supports multiple commands with command queuing features and enables simultaneous reading and writing through the use of separately dedicated paths, doubling throughput.
