Enterprise Storage Drive

The Seagate Cheetah 15K.3 ST336753LC is a 36.7GB 3.5-inch internal hard drive spinning at 15000 RPM with an 8MB cache. It connects via a SCSI Ultra320 80-pin interface and delivers a 3.6ms average seek time. This new bare drive is built for legacy enterprise servers and storage arrays requiring this specific connection standard.

Suited for Legacy SCSI Systems

This drive fits administrators maintaining or repairing older servers that natively support the SCSI Ultra320 80-pin interface and the 1.0-inch low-profile form factor. It is not suitable for systems lacking that specific host interface, nor for users needing larger capacities for modern workloads.

Interface Decides Compatibility

The single specification that determines fit is the SCSI Ultra320 80-pin interface; the drive will only function in a backplane or controller providing that exact connection.

Questions about this item

Does this drive need a SCSI Ultra320 host adapter with an 80-pin connector?

Yes, the ST336753LC uses an 80-pin SCSI Ultra320 interface, so the host adapter or backplane must provide that connector and signalling standard.

Will the 1.0-inch low-profile 3.5-inch form factor fit in the same drive bay as a standard-height SCSI drive?

The drive is a 1.0-inch low-profile 3.5-inch unit; it occupies less vertical space than a full-height drive, so it fits in a standard bay but may leave a gap unless a filler bracket is used.

How can I verify the drive is performing at its rated 15000 RPM and 3.6 ms average seek time after installation?

Run the drive vendor's diagnostic utility or a SCSI-aware benchmark; it will report spindle speed, seek latency and cache operation matching the 15000 RPM, 3.6 ms seek and 8 MB buffer specifications.
