transferring files by USB-C on SL2 is slow

Not sure if this has been addressed before or not, but transferring files by USB-C cable on the SL2 is very very slow.  In contract, I just tried it with the Q3, and it's much faster.

Not all USB C cables are created equal.

A 2.0 only transfers 480mbps while a 3.2 does 20gbps. That is over 4x the data.

USB 4.0 does 40gbps, 8.3 x what a 2.0 does.

Here is an interesting article that describes the differences. USB-C Cable Types: Everything You Need to Know | Laptop Mag

Personally, I plug the SDC card directly into my computer and the transfer is very fast.

According to Leica Tech Data docs for both cameras:

The SL2 is USB 3.1 Gen1 Type C up to 5Gbps transfer speed

The new Q3 is USB 3.1 Gen2 Type C up to 10Gbps transfer speed.

What type of SD card are you using? UHS-II?

Yeah, Tech move on, The New camera has better speed

Let's hope SL2 had USB3.2 Gen 2, 20Gbps, it the camera doesn't get too hot. My SSD gets really hot in use, but then again the speed of SD card is too slow anyway 🤦‍♂️.

I'm using the same cable for both the SL2 and the Q3, and the difference is quite noticeable.

UHS-II.  Same type card for both SL2 and Q3.  And same cable (not Thunderbolt).

My question: why bother with using a cable? You are at your computer, it has a SD slot, or you have a card reader attached. Stick your card into the computer or reader and be done.

Well I like the simplicity of being able to do everything with the USB-C cable and not having to remove the card/reinsert.  Plus a smaller (and perhaps unfounded) part about wear and tear on the card and the door to the SD card slot.
