Which initio card are you giving up on?  There are device drivers for two
types of initio cards last time I looked in the kernel config files (I have no
idea if they work, I've just seen them in existance).
    I don't know about that particular card, but AFAIK, the only scsi
standards capable of hitting 160mb/s are u2w lvd, which means that they have a
huge bandwith, and use extremely low amounts of energy  Only u2w lvd drives
can get anywhere near that amount of data transfer, and the chain is only as
fast as your slowest device, so if you are migrating a regular ole scsi narrow
drive onto a u2w lvd chain, it's only going to go at scsi narrow speeds, which
is about 10mb/s max.
    As a side comment, the state of scsi has gone down hill ever since Apple
stopped bundling one w/ every new mac...
