Samsung has announced the world’s first UFS (Universal Flash Storage) memory cards, which offer 530 MB/s read speeds and 170 MB/s write speeds. Embedded UFS technology is already being used in some newer devices, but there are no products that yet support the cards as removable storage.
The UFS cards have sequential read speeds of up to 530 megabytes per second — five times faster than the best microSD cards. That means reading a 5 gigabyte, full HD movie in roughly 10 seconds, says Samsung, compared to a UHS-1 microSD card which manages the same feat in around 50 seconds. Write speeds are also significantly improved, with rates of up to 170 MB/s. That's nearly double the performance of the very fastest microSDs (this SanDisk Extreme Pro card, for example, has write speeds of up to 100 MB/s), but seven or eight times faster than the cards recommended to non-professionals.
