Product Identity
The Seagate Cheetah 15K.4 ST336754LC is a 36.7GB 3.5-inch internal hard drive spinning at 15000 RPM with an 8MB cache. It uses a SCSI Ultra320 80-pin interface and is supplied as a bare drive. This unit targets legacy servers or workstations that require a high-speed SCSI storage device.
Fit and Exclusions
The drive suits administrators maintaining older SCSI-based arrays or replacing a failed unit in a compatible hot-plug backplane. Buyers whose systems lack an Ultra320 SCSI controller or an 80-pin backplane connector cannot install this drive. The low-profile 1.0-inch height also demands a matching drive bay.
Deciding Specification
The SCSI Ultra320 80-pin interface is the single specification that determines compatibility. Without a matching controller and backplane, the drive will not function regardless of its 15000 RPM speed or 3.5ms average seek time. Verify the host interface before purchase.

Vragen over dit artikel
Will the SCSI Ultra320 80pin interface work with my older SCSI controller?
The drive uses an 80pin SCSI Ultra320 interface. Compatibility depends on your controller supporting that pin count and signalling standard; some motherboards are not compatible with this SCSI interface.
How can I verify the 15000 RPM spindle is running correctly after installation?
Listen for the characteristic high-pitched whine of a 15000 RPM motor and check the drive is detected at 36.7GB capacity in the SCSI BIOS or operating system disk utility.
Does the bare drive include mounting screws or a hot-swap tray for the 1.0 inch low-profile form factor?
The bare drive packaging includes only the 3.5 inch drive unit; mounting screws and any hot-swap tray for the 1.0 inch low-profile height must be purchased separately.
