At my hospital they pump in the blood at a rate of 200 ml per hour. So far I've had 11 red cell transfusions and only 2 units at a time. This is a bit of a pain a few times when I started at about 60, then needed to go back again the next week. They once opened up the saline to 500 ml per hour at the end.
I am thankful for blood donors too. How do you know how many units of red cells they get from a single donor?
