What is all this babble about PIO and stuff.
Just come around with some realworld data everyone easily understands. As the ZII bus can not exeed 3 MB/s so the Buddha as a plain ZII card could not too.
My experiance is about 2.3-2.5MB/s in reallive in an 060 exuipted A2000.
CPU-Load is modearate but you sure feel the difference to SCSI.
All in all you can compare the buddha to the onboard IDE of an A1200/ A600 /A4000 only slightly faster with a little less CPU-load due to way better design and more compatible to modern drives.
Overall the Buddha is the best Zorro IDE controller you can get ( I had an FastATA4000 once, struggeld with it a few weeks and sold it off for half the price - and still felt sorry for the guy that bought it - as I came to the conclusion that I`m way better off with an IDE-SCSI Adapter if I want speed out of an IDE drive on an Amiga)
Haveing said that I won`t use IDE for harddrives at all on an Amiga anymore, as you miss every CPU cycle you lose.
Again, if you can`t affort decent SCSI equipment go for the Buddha.
