What is the difference between a UFS memory card and a TF card

the built-in flash memory of mobile phones has moved towards a ufs new era. Back to the external storage of mobile phones, but also rely on the "old" TF card (micro SD) for hard support, and it is not suitable for larger, more frequent audio, video and image file transfer work, mobile phone external memory card needs to upgrade a grade.

What does a UFS memory card look like, and what is the difference between a TF card?

The question of whether to replace the TF card we put it in the back and say, first look at what a UFS memory card looks like. From the current UFS storage card that Samsung has already released, it has little difference in size from our common TF cards. The front of the memory card remains the brand and storage capacity, and the back is also distributed with metal contacts.

UFS Memory Card

However, in detail, the UFS memory card and the TF card have some differences in appearance. The first is that the grooves on the edge of the storage card are different, the grooves in the normal TF card are sharp and angular, while the grooves of the UFS memory card are smoother (some say shark fins); In addition, the distribution of the metal contacts, the UFS memory card and the TF card are completely different. From the design of the UFS memory card and the metal contact distribution, it is not compatible with all the current mobile products that support the expansion of the storage card.

TF (micro SD) memory card

These are the external differences between a UFS memory card and a TF card, and then say the inner differences between them.

In terms of capacity design, Samsung launched a UFS memory card from the lowest 32GB Take-off, the highest supply of 256GB storage capacity, while the current market of TF card minimum capacity and 8GB, and the largest currently also provides 256GB storage capacity.

In comparison to the differences in capacity design, I believe you are more concerned about how fast the UFS memory card writes/reads.

From this previous media coverage, the UFS memory card has the peak 170mb/s write speed and the 530mb/s read speed. This write/read speed is 2-3 times higher than the top evo+ TF memory card write speed and 5 times times the reading speed respectively. Evo+ is currently write/read the fastest TF memory card, write speed of 50mb/s, reading speed up to 100mb/s.

The standard for UFS memory cards is based on the new UFS 2.0 and compatible UFS HCI 2.0, which supports Full-duplex running in functionality, simultaneous read and write operations, and support for instruction queues. The TF card is Half-duplex, read and write must be executed separately, and the instruction is packaged, so the fast distance of the UFS memory card on the write/read speed.

As for the price, Samsung does not currently give the specific price of these UFS memory cards. However, from the current domestic market 32GB capacity of the top evo+ TF storage card 50 Yuan price estimates, UFS storage card may be the originating price of its 3~5 times.

Will the UFS memory card replace the TF card?

The UFS memory card has the obvious advantage that it is unavoidable to replace the TF card in the future. But for a short time, the TF will continue to exist for a relatively long time. The same, UFS memory card of the popularization of the road also takes time, not only the product technology, cost optimization needs, but also with the industry partners to promote together.

But you don't have to worry about the TF card you're buying, because the development of slots that are compatible with UFS memory cards and common TF cards is on the way. In the future, even if you buy a new device that supports the expansion of your storage card, you can continue to use the previous TF card through a compatible card slot.

UFS memory cards are also available for these scenarios

The UFS memory card has a significant performance boost compared to the existing TF cards, and it can play a larger role in more usage scenarios than for smartphones. For example, it can be used in sports cameras, aerial aircraft, it can record higher quality pictures, images and so on, the real performance of UFS memory card is very worthy of our expectations.
