I think Xperia 1 use UFS 2.1

Indeed it uses UFS 2.1. 

Advantages of UFS 3.0 over 2.1: 

1. About 2x speed of UFS 2.1
2. Less power consumption due to lower voltage 2,5 V vs 2,7 V-3,6 V
3. Works in lowe and higher temperatures (-40 to 105 celsiun) 
4. Constant control of communication channels due to tren and constant monitoring

Hope we will see UFS 3.0 in future xperia devices.

Thanks guys, but I'm still waiting for reply from official support, or they can't answer this just kile camera sensor manufacture info?

Hi guys, sorry for the late response here!

Although we understand the question you have regarding this specification detail, the company has taken the decision not to disclose this information.

I am sorry for any inconvenience this might cause.

J9110 uses Toshiba THGAF8T0T43BAIR, which is UFS 2.1

[azzido2]

I do not understand why they disclose this information. There is nothing wrong with using ufs 2.1, 99.99% of devices on the market uses ufs 2.1. Only One Plus 7 Pro uses ufs 3.0 (while having other issues with screen). Nevertheless people are obliged to know all the technical parameters of device they buy, isn't it against the law?

The problem would be if part of devices uses ufs 2.1 and part ufs 2.0. Oops!...

I was on a support chat. They say it is UFS-I. Maybe that is why they are not disclosing? Additionally, another thread it mentioning the benchmark is 30/30MB read and write...
