performance member of the Seagate 3.5 inch rigid disc family is a companion product to the ST12400 drive
family. It has an embedded SCSI controller. Performance information is given in Section 5. The Hawk 4 Family
interface is defined for functional compatibility to a subset of the Seagate SCSI Interface Specification 77738479,
and the ANSI SCSI-2 and SCSI-3 standards. The Model Hawk 4 Family drives are classified as "Intelligent"
peripherals. The Hawk 4 Family provides Level 2 conformance (highest level) with the ANSI SCSI-1 standard.
Details of the Hawk 4 Family drive SCSI implementation are provided in Section 11 of this manual, (Vol. 1)
and in the SCSI Interface Product Manual P/N 77738479 (Vol. 2; Ver. 2).
