Why is IO better on one motherboard than another?

Question

motherboards

Good afternoon, dear colleagues :) My situation is as follows: I work on Linux on my removable hard drive, which is connected to the computer via a USB 3.0 interface. At home, I have a motherboard from Gigabyte based on the Intel Z77 chipset. I also once came to another workplace where there was a computer with an MSI motherboard based on the Intel Z87 chipset.
So, on the second computer, the speed of loading the OS and applications was about one and a half times higher, maybe a little less, but the difference was noticeable. It was pretty nice. After returning home, I thought a lot about why the IO quality was higher on that computer. Then one person pointed out to me that the chipset model could be the reason, and so far I have remained on this opinion. As you can see, the second mother uses a newer chipset model.
Perhaps someone on the Toaster can say something useful on this topic?) I would be grateful for any useful answers on this issue.

Answer 1

in addition to the system chipset, the matter may still be in the USB controller (for example, some of my ports are processed by the system chipset, and some are processed by a separate asmedia chip).
but the most likely (considering "the speed of loading the OS and applications was an order of magnitude higher"), that USB-2 is used on one computer, and USB-3 on the second.
