The Netra X1 has one ATA bus for both internal drives.
No way to get high perf out of a snail.

SCSI?  Try PATA ;)

Is that good? I don't recall ever selecting that option when purchasing a computer. It seemed safer to stick with SCSI than to try exotic technologies.

Does PATA daisy-chain disks onto the same cable and controller?

If this PATA and drives are becoming overwelmed, maybe it will help to tune zfs:zfs_vdev_max_pending down to a very small value in the kernel.
