Do you agree? There are also phones (motorola edge 50 pro) running UFS 2.2 that equal if not surpass phones running UFS 3.1 in file transfers and random read/write tests.

I think the impact is small due to encryption, the processor used and the file system optimisation that the OEM does. I remember the Nexus 6 where Full Disk Encryption was a controversial topic because it slowed down the Nexus considerably.

Here’s a short video from a youtuber who does a basic test for the Edge 50 pro: https://youtube.com/shorts/EunkoOKhpuk?si=xJBwmltFLNuslyOs
