Good links jc14all,
Exactly the ones I was thinking of.
I have a 29160 card (backwards compatible to 32bit/33mhz PCI bus), I am well aware of the 32/33 pci bus limitations particularly when I run a HardriveTach test, it shows a sustained transfer not that much better than my IDE 7200rpm drive does in the same test.
Although this looks disappointing, I am very pleased with disk-to-disk transfer speeds over the cards own bus.
One day when mainboard manufactures produce a <b>user</b> friendly mainboard with the usual features with 1 or 2 - 64/66 pci slots (there may already be one?) that's not a dual processor board, I will be able to use my SCSI set-up to its full potential, until then I have to put up with about half the bandwidth.
Be wise in your investment choices with SCSI!
