I have couple of questions. Which memory type is faster UFS 3.0 or NVMe and why don’t mobile phone manufacturers like Samsung and OnePlus use NVMe memory?
Give these 2 a go. Might answer what you are looking for.
If you’re talking about Apple phones uses NVMe then I would like to tell you that while watching some videos on YouTube for Disk Speed test I found that UFS 3.0 is much faster than NVMe used in phones.
