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.
