73.4GB 15000 RPM SCSI Ultra320 80pin drive

The Seagate Cheetah 15K.5 ST373455LC is a 3.5-inch internal hard drive with a 73.4GB capacity. It spins at 15000 RPM and includes a 16MB cache. The drive connects via a SCSI Ultra320 80pin interface and measures 1.0 inch in height. It is supplied as a bare drive in new condition.

Suited for legacy SCSI Ultra320 systems

This drive fits servers or workstations that require a 3.5-inch SCSI Ultra320 80pin device with a 15000 RPM spindle speed. Buyers who need a larger capacity or a different interface standard cannot use this drive. Systems without a compatible SCSI Ultra320 80pin controller will not support this unit.

SCSI Ultra320 80pin interface

The single specification that decides compatibility is the SCSI Ultra320 80pin interface. The host system must provide an 80-pin SCSI Ultra320 connection for this drive to function. No other interface type is supported by this model.

Questions about this item

Will the 3.5 inch 1.0 inch low-profile drive fit my standard 3.5 inch bay?

The drive uses the standard 3.5 inch form factor with a 1.0 inch low-profile height so it fits any regular 3.5 inch internal bay.

What is the correct SCSI ID and termination step that installers often miss on the 80-pin Ultra320 interface?

Set a unique SCSI ID with the jumpers and ensure the last device on the bus has active termination or the host adapter provides it.

How long do the mechanical bearings typically last at 15000 RPM before the drive needs replacement?

Enterprise 15000 RPM drives are rated for continuous operation and commonly run for several years; replace when SMART reallocated sectors rise or unusual noise appears.
