10 gigabit per second is equivalent to 1.25 gigabyte per second.
In the real world you would never see 1.25 GB/s though since IP has overhead... you're more likely to see 1 GB/s or 8 Gb/s.
Just pay attention to whether something is showing an upper or lower case B since that's a standard way of showing bits or Bytes.
As for your specific setup, you are hooking your server to diverse switches and using the switch independent teaming mode. When you do that, you will not be able to combine the 2 ports into a single big 20 Gb port.
Instead, what happens is that Windows will basically "round robin" each connection going over one or the other of the NIC ports. So you might be able to get a total speed of 20 Gb/s but not over any *single* network connection.
Your file copy is a single connection so it would only ever use one of the network ports. Your file copy speed is also dependent on other things like the speed of the other system and if your drives can keep up with the network flow.
If you need an actual 20 Gb/s connection then you'll have to use the LACP or static modes and then on the switch side of things you'll need to aggregate those ports into a team. Since your diverse switches aren't stacked, you can't do that.
You could stack your switches or forgo the switch diversity and have both ports go into the same switch as long as the switch supports whatever teaming mode you choose.

For right now, I *think* what you're seeing is that Microsoft shows your team as 20 Gb/s (lower case "b" for bits). When you copy a file, it's only able to use one port for the connection and you're getting a nice 1 GB/s (upper case "B" for bytes) which is what I would expect to see.
If you were able to aggregate both ports by going into the same switch or into a stack, then you would see Windows reporting up to 2 GB/s (giga*byte* per second) which would be normal.
And if you think bits and bytes are confusing, I won't even go into the confusion caused by whether they're talking about base 2 or base 10. Like, whether 1 MB is 1,048,576 (1024^2) or 1,000,000 (1000^2) That's a common source of confusion when manufacturers advertise hard drive capacity so there's actually another standard way of representing those numbers like MiB, GiB, etc. just to avoid confusion.
