Introduction to UFS

Over time, we’ve seen subsequent incremental upgrades in terms of storage options available for smartphones. The same lead to a gradual improvement in the device’s speed and performance. Previously, smartphones were traditionally equipped with eMMC storage standards to store information. However, in the past few years, manufacturers have started using UFS standards in flagship as well as upper mid-range smartphones for better performance.

Notably, UFS 1.0 was announced back in 2011, followed by the introduction of UFS 2.0 in 2013, which was up to 4 times faster than the former. Nonetheless, it wasn’t until 2015 when UFS made its smartphone premiere with the Samsung Galaxy S6. Following the same, several smartphones including OnePlus 3, Google Pixel, etc. came with UFS 2.0 storage standards. While UFS 2.0 has been in the industry for a while and used in many smartphones, we now have the entry of a new standard dubbed as UFS 3.0.

The Universal Flash Storage (UFS) is a standard flash storage specification for consumer electronic devices such as digital cameras, mobile phones, etc. The UFS standard has been developed by the JEDEC Solid State Technology Association with its motif to bring higher data transfer speed and increased reliability to flash memory storage.

Importantly, UFS aims to offer high-performance benefits of the SATA interface used in PCs combined with the flash-optimized low power consumption of eMMC. It is based on the SCSI architectural model and supports SCSI Tagged Command Queuing. It allows the operating system to send multiple R/W requests to the storage, which is not possible with eMMC.

Which phones will come with UFS 3.0 storage?

If you recently bought a high-end smartphone, then it’s most likely to have UFS 2.1 storage. However, recently, OnePlus’s CEO Pete Lau confirmed that the upcoming OnePlus 7 series would incorporate UFS 3.0 storage. That said, Samsung yet again was the first to debut UFS 3.0 on smartphones with its Samsung Galaxy Fold, which unfortunately has been called back over quality control issues.

Indeed, UFS 3.0 is going to redefine the next generation of mobile computing. Let us know your thoughts on this emerging storage standard.
