An anonymous reader writes: Samsung has unveiled the world's first UFS card that could one day replace microSD cards in devices. The UFS card is based on the Universal Flash Storage 1.0 Card Extension standard and will be available in capacities from 32GB to 256GB. With a UFS card, users will be able to read 5GB of data, or a full resolution movie file, in 10 seconds, Samsung claims. For comparison, a UHS-1 microSD card would take 50 seconds to do the same. UFS cards will be able to fit into a wide range of devices like smartphones, tablets, cameras, and drones, but the devices will need a specific UFS card slot, which could take some time. Samsung claims the 256GB UFS card has a sequential read speed of 530MBps. The random read speed is 20 times faster than a microSD card. The sequential write speed is about 170MBps, which Samsung estimates is two times faster than microSD cards. The random write speed is 350 times faster than microSD, Samsung claims. The Universal Flash Storage 1.0 Card Extension standard is intended to replace the eMMC standard, which is used in low-cost laptops and Chromebooks. Samsung didn't disclose pricing or availability for the UFS storage cards. It's worth noting that Toshiba does also make UFS storage cards, but they have yet to release any based on the UFS 1.0 Card Extension standard.
