Interesting points about the specs : "Cache volume: NetWare volume spanning six drives, each with a single 204MB partition" This means they used stripping and only the beginning of disks (where the media rate is the highest). Hard to beat without a well tuned ccd and less than 2 SCSI controllers. (note they also used 10K rpm disks). (PS : 6x4.3Gig for creating a 1.2G filesystem !! what an efficiency !! 4% efficiency is far from a realistic system). Other parameters tend to indicate that all goes to memory and stick there. Is there any specification about a cool-down stage between tests ? Network: "All nets at half duplex". Why not full dup ? they can't ? something hidden with the BT350 ?
