re: SCSI throughput testing. A non-FB SCSI solution might be the *ExpressPro-Tools* available for download from ATTO. <http://www.attotech.com/> It took a bit of digging through their web site but I was able to find and use *ExpressPro-Tools 2.3.2*. This is really to a set-up/SCSI mounter/etc. program specifically for ATTO PCI-SCSI cards and associated disks but there is a SCSI bench marking feature available under one of the menus which works with MacOS9 and 8.6 for sure and doesn't care who's interface card is being used. The installation process seems a little strange and the extension it provides is not needed if all you are doing is benchmarking. It appears to understand RAID, although I have not had need for this. The bench marker allows you to pick a volume and select different size data chunks (32kB to 8MB) for test. It gives a graphical and numeric read-out at the end.
