As title... I'm thinking of a 20Gbps enclosure for a planned M4 Mini or M4Pro Mini...
I've read that on Apple, it would ONLY run at 10Gbps, not the 20Gbps because Apple doesn't support USB 3.2 Gen2x2.
IS THIS TRUE?
Was it true with Thunderbolt 3, but not with 4 and 5?
Does someone KNOW? (as opposed to speculate)
If you connect a Thunderbolt 5 cable to the following you will get the fastest drive currently available, up to 6000 MBS. This of-course assumes you are using the 2024 M4based MM with Thunderbolt 5 inputs.

You may want to speak directly to MacSales, they will happily answer the telephone and answer all of your pre & post sales questions. As they specialize in Macs, everything they sell is well tested and very high quality.
As far as I know, Macs do not support USB 3.2 Gen 2x2.
From what I've read, USB4 defines three different, incompatible "up to 20 Gbps/s" USB transfer modes. One of them has the name "USB4 20 Gbps" and this new mode is mandatory for USB4 host ports. USB 3.2 Gen 2x2 is optional for USB4 host ports – and in effect, has been thrown under the bus.

I haven't heard of any USB4 20 Gbps SSDs or enclosures.
There are several USB4 40 Gbps SSDs and enclosures, from Other World Computing and others, but if you are looking for "lower cost", that probably means a USB 3.0 / SATA or USB 3.1 Gen 2 / NVMe SSD.

No need for you to be rude. Your question also pertained to Thunderbolt 3, 4 & 5. If you did not like the answer all you have to do is ignore it and not be rude.
Does the M4 Mini support a 20Gbps external drive??
