Server-Grade SCSI Drive

The Seagate Cheetah 15K.5 ST373455LW is a 3.5 inch internal hard drive built for high-performance server and workstation environments. It delivers 73.4GB of storage on a SCSI Ultra320 68pin interface with a 15000 RPM spindle speed and 16MB cache.

Low-Capacity SCSI Specialist

This drive suits administrators maintaining legacy SCSI Ultra320 arrays that require the 68pin connector and 15000 RPM rotational speed. It is not for systems lacking a compatible SCSI Ultra320 controller or for deployments needing capacities beyond 73.4GB.

Ultra320 68pin Interface

The single specification that decides fit is the SCSI Ultra320 68pin interface; the drive will only function in backplanes or controllers that provide this exact connection.

Questions sur cet article

How do I connect the 68-pin SCSI Ultra320 interface and set the drive ID correctly?

Plug the 68-pin SCSI Ultra320 connector into a matching controller cable, then use the rear jumpers to assign a unique SCSI ID from 0 to 15 so it does not conflict with other devices on the bus.

Will the 16 MB cache or 15000 RPM spindle require any periodic service or replacement?

The sealed 3.5 inch mechanism has no user-serviceable parts; the 16 MB cache and 15000 RPM spindle are maintenance-free for the life of the drive.

At what point does the 2 ms average latency become the limiting factor during sustained transfers?

The 2 ms average latency is a fixed mechanical characteristic; it defines the minimum random-access delay long before any throughput ceiling is reached.
