New 18.40 GB SCSI Drive
This is a new Seagate Cheetah 18XL hard drive with an 18.40 GB capacity and a 3.5 inch form factor. It spins at 10000 rpm and connects via an Ultra160 SCSI interface. The unit carries a 1 MB buffer.
For Legacy SCSI Maintenance
It suits technicians who need a direct replacement drive for older servers or workstations that still use the Ultra160 SCSI bus. It is not for builders assembling modern systems, for users who require larger capacities, or for anyone without a compatible SCSI controller.
Ultra160 SCSI Interface Decides Fit
The single specification that determines compatibility is the Ultra160 SCSI interface. The host system must provide a matching wide SCSI connector and controller support for this drive to function.

Questions about this item
How do I verify the ST318404LC is running at the correct 10000 rpm after installation?
The drive should be recognised by the SCSI BIOS at boot and report 18.40 GB capacity. Listen for the characteristic high-pitched whine of a 10000 rpm spindle and check SMART data for zero reallocated sectors.
What comes in the box with the Cheetah 18XL and what must I supply myself?
The drive itself is supplied in retail or OEM packing which may vary. You must provide a 68-pin Ultra160 SCSI cable, an active SCSI terminator, a 4-pin Molex power connector and a 3.5-inch drive bay or mounting bracket.
Which Cheetah 18XL capacity should I choose for a legacy SCSI server?
This model is the single 18.40 GB variant (ST318404LC). No other capacities exist in the 18XL series, so select this part number when you need an 18 GB Ultra160 SCSI drive for a 3.5-inch bay.
