I have an external USB 2.0 CD writer drive which is obviously detected correctly:

As one can see, it is detected as drive which is capable of 62 times reading speed and 24 times writing speed - which should be correct. However, when I read a CD - say I rip an audio CD by using Sound Juicer, it is hardly ever faster than 2 times.
Is the detection wrong? Can I configure something that makes the drive faster?
