  • UFS applications range from smartphones to augmented reality and automotive.

What is UFS storage and versions

UFS (Universal Flash Storage) storage has become a key element in the performance of mobile devices, digital cameras and other electronic devices. Although it sometimes goes unnoticed, this type of memory significantly influences the performance of mobile devices. speed y fluency of the everyday tasks we perform with our devices. But how does it really work? What differentiates it from traditional eMMC storage and what are its most notable versions? Keep reading because we are going to clarify all this in detail and without technicalities excessive, so that even those with little knowledge of the subject can understand its importance.

With the rise of smartphones with ever-increasing storage capacities, it is not only the amount of data a device can store that matters, but also how much it can store. Speed that can access that data. That's where UFS storage comes in, which has evolved over the years to offer solutions like UFS 4.0, which promises to be revolutionary. Now, we'll break down everything you need to know.

What is UFS storage?

The term Universal Flash Storage (UFS) refers to a flash storage standard specifically designed to provide a exceptional read and write speed, as well as greater energy efficiency. Its ability to perform simultaneous read and write operations (full-duplex) makes it much faster than its predecessor, eMMC storage. This is essential in applications that require high speed such as recording high-resolution videos or handling heavy data in augmented and virtual reality.

History and evolution of the UFS standard

Since its first appearance, UFS has improved significantly in terms of speed, capacity y efficiencyHere is a summary of the main versions and advances:

  • UFS 1.0 and 1.1 (2011-2012): They laid the foundations for the standard, but did not have mass adoption due to the technological limitations of the time.
  • UFS 2.0 (2013): It introduced improvements in bandwidth and energy efficiency, marking the beginning of its use in high-end devices.
  • UFS 2.1 (2017): Refined the features of 2.0, adding a greater focus on security and stability.
  • UFS 3.0 and 3.1 (2018-2019): They provided a significant leap in read and write speed, as well as energy efficiency. UFS 3.1 remains the most common choice on many high-end devices today.
  • UFS 4.0 (2022): It features read speeds of up to 4.200 MB/s and write speeds of 2.800 MB/s, while being 46% more energy efficient.

Advantages of UFS storage over eMMC

UFS storage stands out over eMMC (Embedded MultiMediaCard) technology in several ways:
