It was probably a good value to use aeons ago when it took a real SLED 3390 16.67 ms. to spin around once, so 8.3 ms. was 1/2 revolution. Today, however, is aeons later as far as the hardware is concerned, especially channel speed when delivering data from controller cache instead of straight from the platter.
