What is cell phone flash memory UFS 3.1?

UFS (Universal Flash Storage) is a high-performance storage solution widely used in smartphones, tablets, and other mobile devices.

UFS 3.1 enhancements and changes over UFS 3.0 and UFS 2.1:

• Read and Write Speed: UFS 3.1 offers a significant increase in read and write speeds compared to UFS 3.0 and UFS 2.1. UFS 3.1 delivers maximum sequential read speeds of up to 2,100MB/s and sequential write speeds of up to 1,300MB/s, while UFS 3.0 delivers maximum sequential read speeds of 2,200MB/s and write speeds of 700MB/s. In contrast, UFS 2.1 delivers In comparison, UFS 2.1 has a maximum sequential read speed of 750MB/s and a write speed of 200MB/s. As you can see, the advantage of UFS 3.1 in terms of storage performance is very obvious.
• Energy Efficiency: UFS 3.1 is optimized for power consumption compared to its predecessors UFS 3.0 and UFS 2.1. The use of more advanced LPDDR4 technology and a protocol similar to NVMe enables higher speeds at lower power consumption. This is important for mobile devices as it means that performance can be improved without too much impact on battery life.
• Write Booster Technology: UFS 3.1 utilizes a new technology called Write Booster, which significantly increases write speeds. Faster write speeds are achieved by caching a small number of write operations and executing them at high speeds along with other slower operations. This is very meaningful to the user’s performance experience in real-world scenarios.
• Deep Sleep (Deep Sleep) Technology: For mobile devices in standby, UFS 3.1 also introduces a Deep Sleep mode that reduces the power consumption of the device during idle states, thereby extending standby time. This feature is a definite boost to the battery life performance of mobile devices.
• Performance Throttling Notification: This feature notifies the host of performance limitations when the storage performance of a UFS 3.1 device is affected due to certain circumstances.

In summary, UFS 3.1 has a number of advantages over UFS 3.0 and UFS 2.1 in terms of read/write speeds, energy efficiency, write speed optimization, and standby time. This not only brings users a faster application loading and data storage experience, but also helps manufacturers improve the overall performance and battery life of mobile devices to a certain extent.

Extension

After the capacity of cell phones has entered 512GB and 1TB storage space, more efficiently managed storage technologies can reduce power consumption in addition to improving the efficiency of memory. In the 5G era, applications such as online gaming and AR/VR are applications that require fast read/write data with large amounts of memory storage, and the high performance performance of UFS 3.1 will be even more complementary.

Which scenarios with UFS 3.1 bring the most intuitive upgrade?

When reading 4K HD movies, UFS 3.1 takes less time, loading takes less than 1/3 of the time required by eMMC 5.1. Accordingly, when experiencing games, UFS 3.1 phones have lower latency and smoother images, allowing our phones to cope with more scenarios without lagging.

Cell phone users in the APP enable speed can feel a substantial increase in the previous can only open an App, now can support multi-tasking and provide cell phone users with a smoother experience, and for large files, large video transmission, the user experience can be clearly felt in the receiving/transferring files, open the video speed is much higher, these are the most intuitive in the use of the upgrade can be felt! These are the most intuitive upgrades that can be felt in the use of the changes.
