Interesting report; will be informative to hear what comes from it:
"Pro users of M1 Macs have reported disappointing transfer
speeds with external SSDs, and tests appear to show that
most M1 Mac Thunderbolt ports don’t support USB 3.1 Gen 2
– which means they don’t offer the maximum 10Gb/s transfer
speeds that would be expected from Thunderbolt 4.
The tests were conducted on a 2021 16-inch MacBook Pro M1 Max,
and a 2022 Mac Studio M1 Max"
