Capacity and interface

The Seagate Cheetah ST373307LW is a 74GB 3.5 inch internal hard drive that spins at 10000 RPM with an 8MB cache. It connects through a SCSI Ultra320 68pin interface and has a low-profile height of 1.0 inch. The bare drive is supplied new without retail packaging.

Enterprise servers and legacy SCSI systems

This drive suits administrators maintaining or expanding Ultra320 SCSI arrays in rackmount servers or workstations that already use 68pin backplanes. Builders whose motherboards lack a native SCSI controller or who need larger capacities for modern workloads should look at something else.

68pin SCSI Ultra320 interface

The single specification that decides fit is the 68pin SCSI Ultra320 interface; the drive will only operate in systems equipped with a matching host adapter and backplane.

Questions about this item

Will the 68-pin SCSI Ultra320 connector fit my existing backplane?

The drive uses a standard 68-pin SCSI Ultra320 interface; verify that your backplane or controller provides the same 68-pin connector and Ultra320 signalling.

Which jumper or termination setting causes the most install issues?

Many builders forget to set the SCSI ID jumpers and enable termination on the last device; incorrect IDs or missing termination will prevent the drive from being detected.

How often should the 3D Defense System bearings be checked?

The 3D Defense System protects the spindle bearings and heads from shock and vibration; no routine bearing checks or lubrication are required during the drive's service life.
