    With performance like that, it sounds like you're saturating a bus
    somewhere along the line. If you're using scsi, for instance, it's very
    easy for a long chain of drives to overwhelm a channel. You might also
    want to consider some other RAID layouts like 1+0 or 5+0 depending upon
    your space vs. reliability needs.
