sounds more like you have a problem with the scsi bus, like
no/bad termination, cable too long etc which only shows up
during 'mixed' usage, like when several devices are active
at once, or many seeks (as opposed to straight reading).

that's a problem many unix machines have, and is not scsi's fault.
for instance DEC and ISC are just fixing (or have fixed) this,
sun seems to take longer (last rumors i heard).
