UltraSCSI

The history of computers has been shaped by getting information in and out of the processor faster, and the history of SCSI has been shaped by trying to open a wider path in and out of the processor. The path, or interface, can become an obstruction that slows down your data traffic. As microprocessors get faster, hard drives get larger and high-speed becomes a necessity. The solution? UltraSCSI.

Until recently, Narrow and Wide SCSI set the standards for speed at 10 and 20-MBps respectively. UltraSCSI doubles those speeds - Narrow SCSI goes from 10 to 20-MBps and Wide SCSI goes from 20 to 40-MBps. Surprisingly, the new SCSI speed limit isn't reached by introducing radical new technology but by making subtle improvements in the delays and hold times of the chip, adding up to great gains in speed. The improved times are the result of new semiconductor technology in the SCSI chip sets.

Because the technology isn't radically altered, UltraSCSI remains compatible with all previous SCSI standards, so it's backward compatible. And since the internal drivers, firmware, and most of the drive circuitry remain the same as your existing SCSI's, you don't have to change your current network topology. In fact, when you switch to UltraSCSI, your peripherals won't be affected at all - all you'll see is better performance.
