@AMIGAZ:
First of all - make sure you have a fairly modern SCSI harddrive in your A3000, good condition SCSI-cables, correctly installed SCSI-termination that is being fed termination power so it actually is working and not just sitting there, and last a working clock-battery.
Then try fiddling with the synchronous settings for the SCSI-controller using either
SetBatt ,
SCSI-Prefs or
SCSIPrefsMUI.
On
this page, under the "Specific Troublesome Devices" section, there are some good tips regarding the A3000 SCSI-hardware.
The A3000 scsi-controller should be able to manage atleast 5MB/Sec in synchronous mode.
As already mentioned by Thomas - a disk-systems transferrate is definately not everything. A DMA capable controller and a harddrive with low seektimes are much more crucial factors to give a responsive system during general use.
Don't stare yourself blind on the transferrates, it is just one aspect of a disk-systems total effectiveness and are thus generally a poor indicator of the overall speed you will experience.
