One of Qru's Associates recently went storage-mad, sweeping together an armada of Ten 9-GIG Quantum Wide Differential Hard Drives. Egads that's a lot of space! Now he has to find a practical use for that much data, either by amassing web clients or leasing data-warehouse size stores of data to corporate clients.

These drives are new, you'll need to pick up a Differential SCSI controller, but when you have data that large, it's really a shame if you don't maximize on that speed with a good bus and data path.

My god, it's full of specs:

• 8ms access time gets to data fast
• 7200RPM spindle motor reduces latency to below 5ms
• Ultra fast 20MB/sec wide differential interface
• Reliability of Differential SCSI and Ultra SCSI-III performance in one card
• Great performance for Mainframe Disk Arrays
• Make that Pentium breathe fire with the fastest Quantum-made SCSI drives!

You get the industrial strength reliability of differential SCSI and Ultra SCSI-III performance in one card. Differential disk drives use high power data transceivers for noise reduction. This eliminates the drop in performance caused by longer cables in standard SCSI systems.

For Use with Differential SCSI Controllers, which allow th use of long cables and more devices to build bulletproof disk arrays for server applications. Disk arrays mirror each other's information and subdivide large stores of data to make querying (retrieving knowledge) take less time. When data is pre-sorted to reflect access trends, most slowdowns are preempted because of all the swap space (elbow room). If something has to move, (data) either finds a space to fit the data, or breaks it into chunks and stows them away. Obviously, the more space, the less chunks, the more optimal the data.

Tried Fast, Wide, or Ultra SCSI? The highest performance, top of the line SCSI products have always used the differential interface in mainframes and fast workstations. Until recently, the high cost of differential drives and controllers has prevented the use of these drives in PC applications. This drive is an ideal match for fast Pentium Pro servers that can waste time waiting for disk access. Get the performance you deserve. Maintain compatibility with the drives you have today, and double your performance with DIFFERENTIAL Ultra SCSI-III.
