Oktagon is a lot SLOWER than built-in IDE. So, no, SCSI is not always better.
I`m not sure about the Powerflyer JJ mentioned later on, but I would actually prefer the Oktagon over the onboard IDE. Or more precise everything (appart from maybe some real stoneage dinosaurs like the A2090) is better then the onboard IDE.
You will only get 2MB/s from the A1200/A4000 IDE and that`s about what the Oktagon will reach too, plus lower CPU usage.
@ JJ
Saying what I have said the Powerfyer migh be the better option for you depending on how much speed you actually archive with it (my guess would be about 5MB/s in real live). As no ZII SCSI controller can surpass 2MB/s by much there will be a major drawback in speed.
If you take a look at a nice ZIII or turboboard controller there is a whole different picture. You will get 5-8 MB/s in real live plus low CPU usage.
So what Turboboard do you have ? If it is a Blizzard 1230/40/60 I strongly recommend that you get yourself an SCSI-Kit.
