The JEDEC Semiconductor Standardization Association recently released a new version of the UFS (Universal Flash Storage) standard with number 2.2. Although the organization has only now officially announced this standard, the launch of the MediaTek Dimensity 800U and Dimensity 720 processors has already confirmed its existence. However, the details of this standard have now been communicated to the public.
The latest version of the UFS 2.x branch so far was UFS 2.1 and 3.x was UFS 3.1. Now there is UFS 2.2, which offers several new features. Here’s what the association says: “The purpose of this standard is to describe the electrical interface UFS and UFS storage devices… It will replace JESD220C, UFS 2.1 and will bring a feature called WriteBooster“…
So, the main difference between UFS 2.2 and UFS 2.1 is the addition of the WriteBooster feature (literally a write accelerator). It improves the write speed of UFS 2.2 over its predecessor. This indicator noticeably affects the performance of the device in some tasks. For the first time, WriteBooster technology was introduced in UFS 3.1 – it implies the use of a faster non-volatile cache, produced using SLC technology.
Today’s entry-level smartphones use eMMC drives, while UFS 2.x support is becoming the norm in mid-range devices. Flagships often offer more advanced USF 3.x drives. Compared to eMMC, UFS drives offer much faster sequential read and write speeds as well as increased random read and write speeds. In addition, UFS can read and write at the same time, process multiple commands at the same time. This makes devices with UFS memory much more responsive.
