Samsung today announced the world’s first removable memory cards based on the JEDEC Universal Flash Storage (UFS) 1.0 Card Extension Standard. These new cards comes in a wide range of storage capacities including 256, 128, 64 and 32 gigabyte (GB).
Samsung’s 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 530 megabytes per second (MB/s) which is similar to the sequential read speed of the most widely used SATA SSDs. 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 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.
