Why UFS 4.0 isn't quite as groundbreaking as you'd think

With so much fuss over some high-end phones sticking with UFS 3.1 instead of 4.0, it's worth asking how much of a difference that really makes

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
