My pc does not have dvd drive inside it, so ive been wondering if i could buy some uotside dvd drive what goes to usb (easy enough to install for me

When games say they require a dvd drive, is the reading speed of usb vd drive same as one that goes inside and so on, hard to find info about this, also it seems usb drives are mostly used for burning and stuff?
but the main question is, can i play call of duty 2 and 4 with a usb dvd drive, is the reading speed enough and so on.
Thank you.
