Which storage solution is right for you

Which storage solution is right for you

The world of technology gives birth to several innovations, in particular with regard to telephones. The integrated eMMC or MultiMediaCard continues to be the standard for flash memory. Meanwhile, UFS or Universal Flash Storage is slowly gaining the upper hand at a progressive rate. This new standard is faster and faster in accessing data without sacrificing power consumption.

But in the end, is this the only difference between the two? Or, is there anything other than what it meets. What is UFS 3.0 capable of?

This is what we will appear in this comparison today as we compare the new UFS standard with the older (but popular) eMMC storage standard.

As it will be a long piece, let’s jump right, okay?

UFS and eMMC: what are they

UFS, unveiled by the JEDEC standards body, is a storage solution that determines how a device’s storage chip connects and exchanges information with the rest of the system. This system is responsible for speeding up data transfer, the application loading time and also the installation time of the application on most phones. And contrary to popular belief, UFS is not limited to smartphones.

It is also used in car media players, VR systems and Chromebooks. While the first iteration of UFS was announced in 2011, the UFS 2.0 standard was released in 2013. The UFS 3.0 standard was released in January 2018 while UFS 3.1 debuted in January 2020.

UFS 3 1

If we’re talking strictly about phones, the Samsung Galaxy S6 was the first phone to launch with UFS storage in 2015.

The MMCA (MultiMediaCard Association) introduced eMMC in 1997. It is therefore a fairly traditional storage solution. However, it is still stable and mainly used in several consumer electronic devices, such as e-readers, smartphones and tablets, among others.

On a more technical level, eMMC is an advanced NAND flash memory which groups a controller outside of the flash memory.

Performance: how fast eMMC and UFS operate

Before we start, let’s clarify one thing. Storage solutions have been designed for faster file copying to improve your overall usage experience on phones and other devices.

Regarding the first generation UFS, it provided a read-write speed 3 times faster than its counterpart.

If we talk about numbers, UFS 3.0 offers sequential readings of 2100 MB / s while writing data at a speed of 410 MB / s. This means that your graphics-rich 3D games will load much faster. Compared to UFS 2.0, there is a massive 6x increase in read speed while the increase in data write speed is around 8x.

When you compare this with eMMC 5.1, there is a 6x increase in random play and an 8.5x increase in sequential reads. Overall, UFS 3.0 offers a peak data transfer rate of 23.2 Gbps. That said, these numbers represent theoretical speeds and the real numbers will be different.

All of these numbers ultimately translate into better multitasking and faster turnaround time. And the sequential read-write factor is the icing on the cake. This increase in speed can be seen when you open a new application or capture a high resolution photo or 4K video.

Unlike him, eMMC is capable of one-way traffic. If you see apps crashing halfway or transfers are taking place at the snail’s pace, you know the reason. So if you need to multitask on your phone with eMMC storage, the system will wait for one process to complete before moving on to the next. Well, in this fast changing world, you have to be very patient with slow speed. EMMC speeds reach a maximum of 400 Mbps with a top speed of around 2 Gbps.

UFS is an advanced storage technology compared to eMMC. It is safe to call UFS as the future of flash storage on smartphones and other devices. That said, the eMMC standard is going nowhere, thanks to the low cost.


The performance of a smartphone depends on many factors, and RAM (Random Access Memory) plays a vital role in it. Simply put, RAM is used by applications and games to quickly move huge chunks of data between the processing core and the file system.

At the same time, it prevents applications and games from making frequent calls to the file system or the kernel to reduce the time taken to execute a call.

For example, if you are playing an intensive graphics game like Fortnite or PUBG (see the PUBG wallpapers), there is a lot of data the phone needs to move around and the RAM acts as temporary data storage.

And this is where RAM with higher bandwidth like LPDDR3, LPDDR4, LPDDR4X and LPDDR5 comes into play. These memory management systems allow a greater amount of data to be moved and are associated with low energy consumption.

The new LPDDR5 RAM can theoretically reach a speed of up to 6,400 Mbps. Meanwhile, the LPDDR4 has provided a maximum speed of up to 4,266 Mbps.

When it comes to phone performance, RAM and UFS complement each other to give a solid boost in performance, especially when it comes to performing memory-intensive tasks like playing videos 4K, high-speed photo shooting, or high-resolution 3D gaming.

Phones with UFS 3.0

The OnePlus 7 Pro was one of the first phones to come with UFS 3.0 in 2019. Since then, there have been quite a few flagship phones with UFS 3.0.

1. Samsung Galaxy S20

The Samsung Galaxy S20 contains a bunch of fantastic features such as a WQHD + screen, a 120 Hz refresh rate and is powered by the Qualcomm Snapdragon 865. It is smooth and fast and the clean look of the One UI 2.0 adds to the overall phone experience.

This phone has a first class camera which offers impressive performance. In addition, the phone comes with a wireless charge, an IP68 protection rating and is water resistant. In addition, it is powered by a 4000 mAh battery, which lasts more than a day on a single charge.

2. OnePlus 8 Pro

The OnePlus 8 Pro is the newest smartphone from OnePlus. With UFS 3.0 and LPDDR5 RAM, it brings a multitude of interesting features to the table. You get a smooth 120 Hz display coupled with a Quad HD + screen. And like its counterpart above, it is also powered by the Snapdragon 865 mobile processor.

One of the main strengths of the OnePlus 8 Pro is the Warp charge of 30 W. This proprietary charging technology quickly accelerates the phone and can recharge its battery up to 50% in just 30 minutes.

Its three-camera configuration offers incredible photos. And unlike its predecessors, the 8 Pro offers flagship features like wireless charging and water resistance.

3. Asus ROG Phone 2

Another smartphone with UFS 3.0 is the Asus ROG 2 phone. With Snapdragon 865 in tow and 12 GB of RAM, it is a powerful gaming phone. It offers a large 6.6 inch OLED screen and a fantastic 120 Hz refresh rate. Thanks to the above features, you get smooth performance combined with flowing visuals.

If you are a serious gamer, you can check out the custom accessories. The phone allows you to connect up to seven different gaming accessories via the additional USB-C ports.

It is powered by a massive 5000 mAh battery and runs on Android 9 Pie and the Asus proprietary ROG user interface.

Storage is better for you

To answer this question, you need to assess several options, such as the use of your device, the type of device you want, and your budget.

As mentioned earlier, eMMC storage is found on inexpensive and inexpensive consumer electronic devices. These devices are designed for light use such as streaming media, browsing the Internet, or simply sending and receiving messages over the Internet.

On the other hand, UFS storage finds its use on devices that promise high performance, speed and multitasking.

The eMMC standard does not make any major improvements over UFS, you should invest in the latter if you plan to buy a future-proof device while multitasking without hitting any bottlenecks.
