Samsung UFS Memory Sticks Shown, Potential Successor to MicroSDs

July 9, 2016, By Sanjeev Ramachandran

The memory stick evolution hit a pause button ever since microSD cards started to flourish across gadgets and devices. But soon, it may be given a run again as Samsung has now revealed the world’s first Universal Flash Storage card, shortly UFS, cards which could replace the microSD in the near future.

Samsung’s UFS cards are based on the SCSI transfer architecture, making the storage capable of accepting multiple commands with command queuing and thereby improving the efficiency significantly. A new M-PHY is also included in the card that is capable of up to 5.8 GB/s per lane.

The revealed memory sticks do offer a potential replacement to the current storage sticks with their relative performance speeds. Samsung’s latest contribution comes with a sequential read speed of up to 530 MB/s, which is more than five times the speed offered by memory cards of today. Samsung explains that a UFS card could read a 5GB full HD movie tin under 10 seconds, while it takes nearly a minute for microSD cards to perform the same.


There’s also a significant jump in the writing speeds, with UFS offering nearly double the speed of micro SDs. Samsung UFS cards come with a write speed of 170MB/s, while the speeds of the fastest available microSD tallies to only 100 MB/s.

As of now, there aren’t any devices available that comes with UFS slot. Unfortunately, the UFS cards won’t fit to the normal micro SD cards. Despite having a similar design and size like those of micro SDs, the UFS cards feature a different configuration making it useless for micro SD slots.

It’s not for the first time that Samsung has wowed the world with this ultra-fast flash memory technology. Samsung has previously used the UFS standard for its Galaxy S6 and S6 Edge devices. But that came embedded in the devices, which makes the new cards the first to feature the technology in a swappable form. The cards are available in 32, 64, 128, and 256 GB versions.
