Samsung UFS Removable Memory Cards Up to 256GB

Process 35,000 random IO/s, reading sequentially at 530MB/s.

Samsung Electronics Co., Ltd., unveiled the industry’s first removable memory cards based on the JEDEC Universal Flash Storage (UFS) 1.0 Card Extension Standard (*), for use in high-resolution mobile shooting devices such as DSLRs, 3D VR cameras, action cams and drones.

Coming in a range of storage capacities including 256, 128, 64 and 32GB, these UFS cards are expected to bring a performance boost to the external memory storage market, allowing much more satisfying multimedia experiences.

Our new 256GB UFS card will provide an ideal user experience for digitally-minded consumers and lead the industry in establishing the most competitive memory card solution,” said Jung-bae Lee, SVP, memory product planning and application engineering, Samsung Electronics “By launching our new high-capacity, high-performance UFS card line-up, we are changing the growth paradigm of the memory c, market to prioritize performance and user convenience above all.

256GB UFS removable memory card – simply referred to as the UFS card – will provide improved user experiences, especially in high-resolution 3D gaming and high-resolution movie playback. It provides more than five times faster sequential read performance compared to that of a typical microSD card, reading sequentially at 530MB/s which is similar to the sequential read speed of the most widely used SATA SSDs. With this UFS card, consumers have the ability to read a 5GB, full-HD movie in approximately 10s, compared to a typical UHS-1 microSD card, which would take over 50s with 95MB/s of sequential reading speed. Also, at a random red rate of 40,000 IO/s, the 256GB card delivers more than twenty times higher random read performance compared to a typical microSD, which offers approximately 1,800 IO/s.

When it comes to writing, the 256GB UFS card processes 35,000 random IO/s, which is 350 times higher than the 100 IO/s of a typical microSD card, and attains a 170MB/s sequential write speed, almost doubling the top-end microSD card speed. With these performance improvements, the 256GB UFS card reduce multimedia data downloading time, photo thumbnail loading time and buffer clearing time in burst shooting mode, which, collectively, can be particularly beneficial to DSLR camera users. To shoot 24 large/extra fine JPEG photographs (1,120MB-equivalent) continuously with a high-end DSLR camera, the 256GB UFS card takes less than 7s, compared to a UHS-1 microSD card which typically takes about 32s, at 35MB/s.

To achieve the highest performance and most power-efficient data transport, the UFS card supports multiple commands with command queuing features and enables simultaneous reading and writing through the use of separately dedicated paths, doubling throughput.

The company has been aggressive in preparing UFS solutions for the marketplace, while contributing to JEDEC standardization of the Universal Flash Storage 2.0 specification in September 2013 and the Universal Flash Storage (UFS) 1.0 Card Extension standard in March 2016.

Following its introduction of the industry-first 128GB embedded UFS chip in January 2015, the company launched a 256GB embedded UFS memory for high-end mobile devices in February of this year. As of earlier this month, Samsung also completed the Universal Flash Storage Association (**) (UFSA)’s certification program that evaluates electrical and functional specifications for compatibility of a UFS card, and firm’s UFS card products were approved as UFSA-certified UFS cards with the right to use the official UFS logo for the first time in the industry.

(*) The company has taken a leading role in standardization of JEDEC Universal Flash Storage (UFS) 1.0 Card Standard, and filed seven design patent applications to USPTO (US Patent and Trade Office) which the company disclosed to all JEDEC members under the RAND (reasonable and non-discriminatory licensing) condition that allows manufacturers to develop UFS card products without royalty. Royalty payment usually encompasses a significant portion of other types of removable card manufacturing.
(**) UFSA announced the release of a Universal Flash Storage (UFS) Compliance Test Matrix in April 2016.
