Everything You Need to Know About UFS Memory Cards

UFS ( Universal Flash Storage ) memory cards are being developed, and the first examples of these ultra-fast cards have just been officially introduced by Samsung . 

These memory cards are much faster than microSD cards and are well connected to advanced smartphones.

The production of UFS or Universal Flash Storage memory cards is on the rise. Samsung has just unveiled its first product, and many other companies are preparing product lines for this type of memory card. . UFS memory cards will be built according to the JEDEC Universal Flash Storage 1.0 Card Extension standard. The wave of universal flash memory production is expected to start next year.

So far, little information has been publish about UFS memory cards. Some reports have suggested that these memory cards can act as a replacement for eMMC storage modules used as smartphones’ internal storage. In fact, Samsung has used this type of memory to produce the Galaxy S4, Galaxy S4 and other flagships behind these phones. Here are some of the advantages, disadvantages, and disadvantages of Universal Flash Memory.

External memory very fast

The biggest advantage of UFS memories is the high speed of reading and writing. These memory cards have a read speed of 530MB / s, while the fastest read speed is 156MB / s on the fastest type of microSD card, the UHS-II class. UHS-II class microSDs, of course, will be faster when they are just reading or writing (Half Duplex) and reading speeds of up to 312MB / s, which will be lower than the speed of UFS cards.


According to the diagram below,

we find that the speed of reading and writing in universal flash memory is much higher than in microSD cards. The first example of UFS caches have a maximum read speed of 530MB / s and a maximum write speed of 170MB / s. However, the maximum read speed on UHS-II-class microSD cards is 1MB / s, and the maximum write speed on these cards is 1MB / s.

The UHS-I class microSDs also have a read speed of 2 MB / s and write speeds of 1 MB / s. The thing to note is that conventional microSD cards used by users today under the class name are much slower than UFS memory and only expensive microSDs can read speeds up to 5 MB / s. As a result, UFSs are at least 2 to 3 times faster than microSD cards.


Another factor that Samsung mentions in its product launches as an advantage

of these types of memory cards is the number of Input / Output Operations Per Second (IOPS) . However, this factor is not as reliable for comparing memory card speeds and is more applicable to hard drives. The numbers provided for maximum speeds can also be varied under different conditions, such as memory overload.

On the other hand,

today’s memory cards have no problem working with media content such as 1080p videos

and high quality photos, but with the advent of gadgets and media content such as 4K videos,

RAW images and advanced graphics games, the need for faster memory cards is even greater. Feels.

More battery life

Normally, with increased speed and efficiency, battery consumption will also increase. But Universal Flash memory has also made good progress and consumes less energy than the fastest microSDs. The fastest microSD memory cards consume 2.5 watts of power while reading and writing, and require 3.5 watts of idle time. But according to UFS reports, these memories consume up to 1.2 Watts of power, far less than microSDs. They also consume almost no power when idle or idle.


Integrated memory for storing apps

One of the reasons that some applications do not allow users to install on external memory card is

the low speed of the memory compared to the internal memory which slows down the application performance. As UFS cache evolves, bulky, high-end graphics applications can also be stored in external storage. UFS caching makes applications easily cached and run at maximum efficiency and speed. In addition, the high speed of these memories reduces the amount of RAM used while writing and reading at the same time. Other advantages of Universal Flash memory in this regard can be reduced latency and faster random access to memory. This feature is very useful with the development of multi-core smartphones.


Another great advantage of Universal Flash memory is the ability to use them as temporary RAM. These caches have an integrated memory format that allows the software to use them as RAM when needed. It’s not yet clear whether this feature will be supported by operating systems like Android.

The biggest drawback to these new memories is their electronic pin system.

The system is newly designed and different from the layout of current microSD cards. This way, current smartphones cannot use these memory cards.


However, Samsung has begun using UFS memory as internal storage

and there is certainly no time is to use it as an external memory card. Experts believe one can expect this type of memory card to be widely available by the end of the year or the beginning of the year.
