I just read that too. AFAIU it's been measured with LC475, which may 
already be a good result. Unless that's the limit of the device, a fast 
Amiga should do better than that. If memory still serves I had some 5-6 
MiB/s with WarpEngine's SCSI and around 2-3MiB/s with A3000's onboard 
SCSI. In any case more or less twice the speed of the harddrives I used 
earlier.

The onboard PATA of A4000 was slow (like 1-1.5MiB/s) but FastATA on ZIII 
bus kicked hard, getting to 8+MiB/s with CSII/68060
