Our main computer doesn't have a memory card reader. I use this to check SD cards from our trail cameras. This is handy for viewing results on my iPad's big screen. It's also nice when I want to upload a screenshot to my iPhone. It is also great for uploading old photos that we have stored on SD cards. I honestly don't know anything about the speed or the technical details. All I know is that it works fine for the purpose I have it for.
