The Aztec works fine in my A3000. I have the newer SCSI chip, and I had to disable termination. After I got that working (about 3.75MB/s), I put it on my Warp040 board's SCSI... now I get 8MB/s. 
Those should be pretty fast since he just integrated the acard 7720 with a cf into 1 board. some people have reported problems with them,but hard to tell if it was just a termination issue or missing term power(diode d800 on 3000 bad or wrong way round?). Might even be the firmware rev.
It is too bad there is not a $50 version of it. Maybe someone should build one(hint jim hint hint)
