I'm currently syncing a bunch of files to a USB stick.
Regardless of what USB version it uses, and regardless of my motherboard's ability to transfer USB data, why does it cause my entire computer to crawl on its knees?
I'm not talking about the USB mouse and keyboard. I'm talking about opening image files on my SSD system disk, for example. Or rendering webpages in my browser. How can that kind of thing be affected by a heavy USB data transfer from my very fast system disk to a (possibly slow, but not really) USB stick?
It's as if my entire machine is temporarily brought down as long as the file copying (robocopy in this case) goes on. I don't understand how it's logically possible.
Looking at what the command is doing, it's currently loading various 35 MB large image files over, taking a number of seconds each. Alright, so maybe the USB memstick is relatively slow, but so what? Why does that effect the rest of my system? I've always been confused about how USB seems to be some sort of voodoo technology which sometimes doesn't work at all and sometimes does work and sometimes brings down the machine to its knees and sometimes does not. Whenever USB is involved, especially when transferring files or using the data bus "heavily" (presumably), it seems to cause all kinds of issues to Windows.
Why is this? What technical explanation can you offer?
