hold on... 5 Gigabit/s = 5000 Megabit/s correct?
divide 5000 by 8 and you get 625 MB/s.

right? of course I understand this is all theoretical, and you usually only see half that in real world use.

I know most hdd's only do up to around 200 MB/s, MAX, and that's a really good one at sustained speeds over a long run... ssd's are much better, mostly getting into the high 300's, sometimes more depending on what's feeding it.

in any case... can a usb type-a connector transfer anywhere near this high?

to continue this thread, I installed the card I linked earlier...

I hope another better card comes along, as the drivers for this one a little finicky to install. had a couple blue screens on installation/uninstallation.
but it seems stable enough after install. I got transfers from one usb3 ssd device going from the intel usb3 ports native to the motherboard thru to this card and out to another usb3 ssd at 250 MB/s sustained, which is not bad.
don't have anything to plug into the type c connector right now, so nothing to test there.
haven't done crystaldisk benchmark yet.
