Universal Flash Storage (UFS) is a common flash storage specification for digital cameras, mobile phones and consumer electronic devices. This could bring higher data transfer speed and increased reliability in flash memory storage, thus reducing market confusion and the varying number of adapters for different number of cards.
The proposed specification is supported by leading firms in the consumer electronics industry such as Nokia, Sony Ericsson, Texas Instruments, STMicroelectronics, Samsung and Micron. The electrical interface for UFS uses the M-PHY., developed by the MIPI Alliance. organization. This offers the possibility of higher speed, ease of integration into embedded applications, and lower power consumption compared to SD cards. Universal Flash Storage uses a SATA 300 MB/s internal connection, about three times faster than e•MMC. Unlike e•MMC, Universal Flash Storage uses the SCSI architectural model.
The standard is developed by, and available from, the JEDEC Solid State Technology Association. JESD220A Universal Storage v1.1 was released in June 2012 (being an update to v1.0 from 2011).
The Linux kernel supports UFS.
