Samsung discovered world's first UFS memory cards — the successor to microSD
What comes after microSD cards for removable storage? Samsung has the answer: UFS. The company announced today the world's first removable UFS (Universal Flash Storage) memory cards, offering storage capacity of either 32, 64, 128, or 256 gigabytes, and performance speeds that simply blow older formats out of the water. Read speeds five times faster than the best microSD cards 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 im proved, 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
