Seagate Cheetah 15K.5 73GB Ultra320 SCSI Drive

This 3.5-inch internal hard drive operates at 15000 RPM with a 16MB buffer. It uses the Ultra320 SCSI interface standard via a 68-pin connector. The Cheetah 15K.5 series targets enterprise environments that demand high spindle speed and low latency for transactional workloads.

68-pin SCSI installation and common issues

The drive fits a standard 3.5-inch bay and connects with a 68-pin Ultra320 SCSI cable. Ensure the SCSI ID is set correctly via jumpers and that termination is configured for the bus position. A mismatched ID or missing terminator will prevent the drive from being detected by the host adapter.

Verify host adapter and bus compatibility

Confirm your system has a compatible Ultra320 SCSI host adapter with an available 68-pin internal connector. Check that the SCSI bus can accommodate the additional device ID and that termination requirements are met. The drive requires a 3.5-inch mounting bay and standard power connection.

Questions about this item

How can I verify the ST373455LWProduct is running at 15000 RPM after installation?

Listen for the high-pitched spindle whine typical of 15000 RPM drives and check the SMART data or SCSI inquiry pages reporting 15000 RPM spindle speed.

Does the ST373455LWProduct include a 68-pin SCSI cable or mounting bracket in the box?

Retail or OEM packing may vary; the drive itself is the only guaranteed item. Cables, brackets and terminators are not included and must be sourced separately.

Which capacity version of the Cheetah 15K.5 should I choose for a 73 GB requirement?

The ST373455LWProduct is the 73 GB model; other capacities in the 15K.5 series carry different part numbers and are not this product.
