There are a couple of points to consider here: 1. The 1522 is a low-performance board. It doesn't have much advantage over IDE. 2. On a UNIX box, you do many things at the same time. File transfer speed isn't as important as it is on a simple system like DOS: you should also consider what you do in between data transfers. For a better example, try running two disk and CPU intensive programs at the same time, or time a copy from one disk to another, preferably while accessing a third disk at the same time (OK, you'll need 2 IDE controllers for that, but that's OK).
