Capacity and interface

This is a Seagate Cheetah 15K.5 desktop internal hard drive with 300GB capacity and a SCSI Ultra320 80pin interface. It spins at 15000 RPM and includes 16MB cache for enterprise workloads. The 3.5 inch form factor fits standard drive bays. The unit is supplied as a bare drive.

Enterprise workloads vs other needs

It suits administrators maintaining legacy SCSI storage arrays or servers that require the 80pin connection and 15000 RPM performance. Buyers who need a different interface or larger capacities should look at something else. The bare drive packaging means no cables or mounting hardware are included.

SCSI Ultra320 80pin interface

The single specification that decides compatibility is the SCSI Ultra320 80pin interface. Your host adapter or backplane must provide this exact connection for the drive to function. Verify the interface before purchase.

Questions sur cet article

How long before the 15000 RPM spindle hits its thermal limit under sustained writes?

The 2ms average latency spec is measured at steady-state temperature, so the drive is designed to maintain that figure continuously.

What noise and heat should I expect from the 15000 RPM mechanism running all day?

The 15000 RPM Cheetah 15K.5 runs hotter and louder than slower drives; plan for active airflow across the 3.5" chassis.

Which controller card or backplane do I already need for the SCSI Ultra320 80pin interface?

You need a SCSI Ultra320 host adapter or backplane with an 80-pin connector; the bare drive has no onboard controller.
