OH, that fantastic PIO 5 speed works out to less than 7 MB/s in my testing, which is still better than 2.4.
Yep you can never get quite the speed that's advertised (15 MB/s).
I brought one for my 1200 and got about 9 MB/s using a SSHD (module) with my 80Mhz 1260.
I couldn't get the thing to fit with my Indy Mrk2 so I didn't bother using it in the end (it's still sitting in the box on the shelf!).
For reference the IdeFix Express is meant to go up to 5.1 MB/s but the best I could ever squeeze out of mine is 4.6 using an ACA1230 @ 56 Mhz, my Apollo 1260 managed about 4.3 MB/s but my Blizzard is down to 3.9 MB/s.
Oh well, still better than the crappy 1.9 MB/s standard IDE speed
