Ultra320 SCSI on the Adaptec SCSI Card
39320D
The Adaptec SCSI Card 39320D enables you to connect up to 30
SCSI devices—such as very large arrays of high-performance hard
disk drives, external storage subsystems, Ultra320/160, or Ultra2
hard disk drives, scanners, and CD-ROM drives—to any Intel-
based computer with 64- or 32-bit PCI/PCI-X expansion slots.
Ultra320 is an enhanced SCSI technology that transfers data at up
to 320 MB/sec. Ultra320 SCSI allows cable length of up to 12
meters for optimal connectivity and flexibility.
