Enterprise 450 GB SAS drive

The Seagate Cheetah NS.2 ST3450802SS is a 450 GB 3.5-inch internal hard drive built for server environments. It spins at 10000 RPM with a 16 MB cache and connects via a SAS 6Gb/s interface. The drive is supplied new as a bare unit without a tray or mounting hardware.

Bare drive packaging changes installation

Because the drive ships as a bare unit, no tray, screws or cables are included. Installers must provide a compatible 3.5-inch SAS backplane or caddy and the appropriate power and data cables. This packaging suits integrators who already stock mounting hardware in quantity.

450 GB capacity with 10000 RPM speed

The 450 GB capacity handles operating-system volumes, database logs and tier-1 application data that benefit from low 2.98 ms average latency. Workloads needing multiple terabytes or archival cold storage will exceed the available space and should consider higher-capacity alternatives.

Questions about this item

Will the 16MB cache or 10000 RPM spindle require any scheduled maintenance or replacement?

No scheduled maintenance is required for the cache or spindle; the drive is a sealed unit and runs until replacement is needed.

What is the first performance limit reached during sustained operation, the SAS 6Gb/s interface or the 2.98ms average latency?

The 2.98ms average latency of the 10000 RPM platters is the first limit encountered during sustained workloads.

How much heat and noise does the 3.5" 10000 RPM drive produce when running all day in a server?

The Cheetah NS.2 is engineered for over 20 percent lower power than comparable drives, reducing both heat output and electrical draw during continuous operation.
