Samsung has just unveiled the world’s first removable Universal Flash Storage (UFS) memory cards that might be the successor to Micro SD. Thanks to a number of features including storage capacity and performance speeds, UFS are actually better than Micro SD. The new memory cards offer storage capacity options of 32, 62, 128 or 256 gigabytes and have sequential speeds of up to 530 megabytes per second, which is approximately five times faster than the best micro SD cards.
UFS’s sequential speeds mean that they can read a 5 GB full HD movie in roughly 10 seconds, which is way faster than a UHS-1 micro SD card, which can read the same movie in around 50 seconds. The UFS at a random read rate of 40,000 IOPS, can offer more than 20 times higher random read performance when compared to a typical micro SD that offers about 1,800 IOPS.
UFS also features significantly improved write speeds, with rates of up to 170 MB/s. This is nearly double the performance of the fastest micro SD and about seven to eight times faster than cards recommended to non-professional. The 256GB UFS card processes 35,000 random IOPS, which represents close to 350 times higher than the 100 IOPS offered by a typical micro SD.
With these substantial performance improvements, it means that the UFS cards can reduce buffer clearing time in burst shooting, multimedia data downloading time, photo thumbnail, all who can are beneficial to DSLR camera users. UFS card can also support multiple commands with command queuing features, enabling simultaneous writing and reading through the use of separate dedicated paths.
Samsung noted that their new cards would provide an ideal user experience for the digitally-minded consumer and establish a competitive industry based on performance. The company further indicated that the memory card line-up would change the growth paradigm of memory cards market to prioritizing performance and user convenience above all.
The price and availability have not yet been announced.
A crucial factor that might derail their adoption is their incompatibility with current devices, except in Samsung’s Galaxy S6 and S6 Edge where they have appeared as embedded memory.
