Recently, the "2020 Storage Industry Trend Summit (MTS2020)" was hosted by Dramexchange. That is a semiconductor industry research center. It works under the global high-tech industry market research organization “Jimbon Consulting”. The summit was held in Shenzhen. They discussed smartphone storage trends in 2020, especially the UFS flash.

In terms of smartphone production, analysts believe that the production of smartphones has remained roughly 1.4 billion in the past two years. This number shows that the development of smartphones has reached a relatively saturated stage.

They also discussed hardware trends. According to analysts, the future smartphones will focus on improving their experience. This involves multi-camera photography. They also considered under-screen fingerprint unlocking and high-frame-rate displays. What about storage, analysts made the following predictions. Firstly, the UFS flash will be really suitable for 5G generation smartphone devices. Then, EMMC has gradually become difficult to support the basic transmission requirements of the 5G era. So, It will be rapidly replaced in the next few years. By the end of next year, UFS will exceed 40% of the penetration rate. However, some smartphones are using EMMC specifications currently, most of which are low-to-mid-end products.

Universal Flash Storage is a common storage standard for smartphones, digital cameras and consumer electronic devices. UFS adopts serial data transmission technology. So, it can read and write data at the same time. This makes it have much higher data transmission efficiency than the original EMMC.   Presently, the most commonly used storage standard is UFS 2.0 and UFS 2.1. However, the latest standard is UFS 3.0. The UFS 3.0 was first released on January 30, 2018. It has twice the bandwidth of the current UFS 2.1. The data transfer speed of the UFS 3.0 can reach 23.2 Gbps (11.6Gbps in two lanes). These data transfer speeds determine the speed at which smartphones read or write content from storage. So, they can affect the speed at which the smartphone loads games or applications. They can affect the time it takes to copy video files to storage, too.
