UFS 4.0 Specifications, Speed Test, UFS 4.0 vs UFS 3.1

For a long time, Android smartphones were playing catch-up with Apple iPhones when it comes to smartphone storage speed. Android flagships always used Samsung-made UFS flash storage and Apple used NVMe storage which is significantly faster than UFS. But With Samsung’s new UFS 4.0 storage they finally surpassed Apple’s NVMe storage performance. Read our UFS 4.0 VS NVMe comparison.

What is UFS storage?

UFS stands for ‘embedded Universal Flash Storage. Previously Samsung’s high-speed UFS offered much faster data processing and greater energy efficiency than the eMMC (embedded Multimedia Card) storage. But it was slower than NVMe (nonvolatile memory express) storage.

Depending on what type of storage is used on a smartphone, it affects the performance of the device like app opening speed and file export speed. That’s why smartphone manufacturers always use the fastest available storage on their flagship phones. IQOO 11 was the first phone to come with UFS 4.0 storage in the market. After that other manufacturers quickly started adopting this new generation of flash storage. That being said, android flagships with the new UFS 4.0 flash storage will have significantly improved performance.
