IBM ST318452LC 18GB 15000RPM Ultra160 3.5" SCSI internal hard drive

18 GB Ultra160 SCSI drive for legacy servers

This new IBM ST318452LC is an 18 GB internal hard drive spinning at 15000 RPM on the Ultra160 SCSI interface. It targets administrators maintaining older 3.5 inch SCSI storage arrays or workstations that require a direct replacement drive. The unit ships with an included caddy tray for mounting in compatible bays.

Straightforward caddy installation

The supplied caddy lets the drive slide into a standard 3.5 inch hot-swap or fixed bay without extra brackets. Installation fails most often when the SCSI ID jumpers are not set uniquely or when the bus termination is missing or doubled at the end of the chain. Verify the ID selection and ensure only the last device on the cable is terminated before powering on.

Check controller and cabling before ordering

Confirm your host adapter supports Ultra160 (160 MB/s) signalling and provides the correct 68-pin connector for this 3.5 inch drive. The system backplane or cable must deliver single-ended or LVD termination matching the drive configuration. Ensure an available power connector and that the operating system recognises 18 GB SCSI volumes without special drivers.
