Are 2022 MacBook ports USB 3.1 Gen 2.2 ?

Yes, it does...

Thunderbolt 4 (40Gb/s) > USB 4 > USB3.2 Gen 2.2 (20Gb/s) ...

"Backwards compatible"

p.s. - there is no "3.1" they changed the names again a while back... go figure...

However, do remember to get a high quality certified cable that supports the "20Gb/s or 40Gb/s." Nowadays, there are so many cables that say they "meet" the standard but they fall short due to cheap components... and then you get horrible speed results...

The ‘x2’ means that it uses 2 bus lanes each 10Gbps…

However, now that I look at it in detail:

and

https://support.apple.com/en-ca/HT201163

it all points out that it looks like Apple hasn’t implemented the ‘x2’ 20Gbps standard yet… and knowing that this has been out for a few years, they might not do it…

so it is all 40Gbps or 10Gbps… no in between…

See the following from https://www.apple.com/macbook-pro-14-and-16/specs/

I have this exact sandisk pro ssd and the new 16” MacBook Pro. I can confirm, disappointingly, I am only getting the same speeds I had on my 5yr old MacBook of around 950MBs (10Gbps)

You just saved me a lot of money
