Can the new 2021 MacBook Pro handle SSD drives that utilise USB3.1 Gen 2.2 to their full potential through the latest USB4 ports?
I have the Sandisk Extreme Pro which can read at 2000mb/s but until recently, the USB4 ports could only handle 1000mb/s due to only being Gen 2.1?
Thanks

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:

https:https://support.apple.com/en-ca/HT201163
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…
But what confuses me, is that the MacBook Air M1 also has USB 4 (and Thunderbolt 40Gb/s) and yet the USB-C port is still only USB 3.1 Gen 2 (10 Gb/s)
so what’s different with the 2022 MacBook Pro USB-C ports that makes them Gen 2 x 2 ?
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)
:-(
Thank you, but that doesn’t advise if it actually supports the USB3.1 Gen 2.2 protocol
Thanks 👍
You just saved me a lot of money

Thanks 👍
Are 2022 MacBook ports USB 3.1 Gen 2.2 ?
