I configured a DPT-3334UW on a K6-II/400 machine with 4 9G SCSI drives. I found that for creating and deleting files, it couldn't be beat (Ports would untar 4 times faster, for instance). However, I found that a single 9G on a 2940UW would easily beat the raw throughput. I was dissapointed with this.
