Well I haven't seen that, but I don't think SCSI garurentees that a dead
disk won't block the bus.  Of course with a 3ware controller each disk
has it's own bus so that isn't a problem.  Nice advantage to have over
scsi based raid actually where the connector is in fact a single point
of failure which can potentially be killed by a dead disk, although it
seems usually the disk just stops responding, or the electronics survive
enough to tell the controller it is dead and disconnect itself.  IDE in
general will kill the bus if a disk dies, which is why you should not
run raid with more than one disk per connector on ide.
