Universal Flash Storage, known as UFS, is the flash storage standard that is used in flagship phones and upper mid-range phones. The Samsung Galaxy S6 was the first phone to use UFS storage in 2015. In the years since, it has slowly been spreading to lower-cost segments of the market, to the point where the newest lower mid-range phones now also have UFS storage.

UFS storage is much faster than the eMMC flash storage standard, which is still used in budget phones.

The UFS 3.1 JESD220E standard brings three key improvements over UFS 3.0.
• First of all, it has a Write Booster, a SLC non-volatile cache that amplifies write speed.
• Secondly, new UFS device low power state called DeepSleep targets lower cost systems that share UFS voltage regulators with other functions.
• Finally, it has a Performance Throttling Notification that allows the UFS device to notify the host when storage performance is throttled to high temperature.

The use of an SLC non-volatile cache is probably most crucial feature here, as it will help improve real-world performance. This technology is used in devices that use mobile NVMe SSDs, such as the Apple iPhone and iPad. Also, all of these features are already supported by SSDs, so the inclusion of these features in UFS 3.1 will help close the gap between the two.

It’s not as big an update as UFS 3.0 was over UFS 2.1 (as the theoretical top bandwidth speed remains the same at 23.2Gbps), but the real-world improvements in storage performance and battery life for lower cost devices will be welcome.
