On a sustained read, roughly 2/3's as fast. Also depends on where on the
platters the data resides. The quad core is probably not doing much for
you and the the clock speed of the slow box is only about 3/4 of the
fast box. Just a hunch though, I don't think the difference is all
hardware caused, I think you have something else going on with the slow
one.
