First UFS Card Introduced by Samsung
The new technology memory cards are now introduced by Samsung now available in the market. UFS stands for universal flash storage. The Samsung UFS cards are available in 256GB, 128GB, 64GB and 32GB capacities and are apparently capable of transfer speeds and IOPS well beyond the ageing MicroSD standard. The UFS technology is a common flash storage standard that is maintained by the JEDEC consortium (which contains all of the usual big hardware players).
UFS apparently replaces both eMMC for embedded flash and SD cards for external flash. Most memory manufacturers (Micron, SK Hynix, Samsung) and some phone companies such as (Samsung, Nokia) are supporters of the spec. The UFS spec has been around since 2012, and it was updated in 2013. It was sparingly used in embedded form but not in the external cards for the time being.
Samsung claims that its 256GB UFS card is competent of sequential reads five times faster than the typical MicroSD card and topping out at 530MB/s. This read speed is associated with SATA-based SSD drives like Samsung possess Evo 850. The random read speeds are also good, rated at 40,000 IOPS. The UFS 2.0 interface is capable of providing speed of today’s SATA SSDs for PCs. The writing speed is not as similar as the read speed but better than the best standard MicroSD cards, with speed up to 170MB/s. The speed of a professional MicroSD card for example SanDisk tops out at 100MB/s. This kind of speed makes the UFS cards more powerful to use and the speed is great for Android adoptable storage features. Those features which let you pool internal and external storage as well as with digital cameras.
