Default Better bandwidth than USB-2?

When I can, I use the hardware monitor on the interface.

I just thought that if the hose was pushing water a lot faster (USB3)
then the round trip would be faster. It sounds like you guys are saying
that USB2.0 is fine, and that the latency comes from the CPU.

The latency comes from a lot of things, starting with the USB driver and
the handshaking protocol between the chip on the motherboard and the
device being connected when they start exchanging data.

Then there is the delay between the data being accepted and hitting the
memory, which depends on the quality of the software, the amount of RAM,
how busy the CPU and, on some systems, the Graphics Processing Unit are.

The main advantage of USB 3 is that it deals better than USB2 with large
files and streaming data.
