18.4 GB Ultra-160 SCSI drive

This 18.4 GB internal hard drive uses a 3.5-inch Ultra-160 SCSI 80-pin interface and spins at 7200 RPM. A 2 MB buffer handles burst transfers for legacy servers or workstations that still require wide SCSI connectivity. It suits administrators maintaining older arrays or replacing failed drives in certified configurations.

Thermals noise and power in normal use

The drive operates at standard 3.5-inch form-factor power levels with a 7200 RPM spindle. Acoustic output and thermal load are consistent with enterprise SCSI drives of this generation. No active cooling beyond typical chassis airflow is specified by the manufacturer.

Build integration requirements

An 80-pin SCA-2 backplane or adapter supplies both data and power through a single connector. The unit fits any 3.5-inch bay with the correct SCSI termination and ID configuration. It frees a standard 4-pin Molex connector but requires a compatible Ultra-160 host bus adapter or RAID controller.

Questions about this item

How do I install the 80-pin Ultra-160 SCSI drive into a 3.5-inch bay and what step is often missed?

Slide the drive into the hot-swap carrier or backplane until the 80-pin connector seats firmly; the step often missed is setting a unique SCSI ID via the jumpers on the drive before powering on.

What maintenance or replacement will the ST318436LC need over time?

The 7200 RPM motor and bearings are the primary wear items; after years of continuous operation the drive may develop seek noise or SMART reallocated-sector counts that signal replacement.

What limit appears first during sustained transfers on this 18.4 GB Ultra-160 SCSI drive?

The 2 MB buffer fills quickly, so the sustained throughput ceiling is the physical media transfer rate of the 7200 RPM platters rather than the 160 MB/s bus limit.
