Enterprise SAS Hard Drive

The Seagate Constellation ES ST500NM0001 is a 500GB 3.5-inch internal hard drive built for 24×7 enterprise operation. It runs at 7200 RPM with a 64MB cache and connects through a 6Gb/s SAS interface. The bare drive carries an MTBF of 1.2 million hours and FIPS 140-2 validation for data security.

Server and Array Installations

This drive suits administrators deploying nearline storage in servers or multi-drive arrays where SAS connectivity and rotational vibration tolerance are required. Buyers who need a different interface or capacities beyond 500GB should look at other models.

SAS 6Gb/s Interface

The 6Gb/s SAS connection determines whether this drive fits the target backplane or controller. Verify that the host system provides a compatible SAS port before purchase.

Questions about this item

How much power does the 7200 RPM SAS drive draw during continuous 24×7 operation?

The Constellation ES is built for the lowest power consumption of any nearline 3.5-inch drive and includes PowerChoice technology for on-demand savings during idle periods.

What host interface must my system provide for this SAS 6Gb/s drive to work?

A 6Gb/s SAS host bus adapter or RAID controller with a compatible SAS port is required; the drive uses a standard SAS connector.

Will the 3.5-inch form factor and SAS interface let me add this drive to an older server that uses 3.5-inch SAS bays?

Yes, the drive fits a standard 3.5-inch SAS bay and its 6Gb/s SAS interface is backward-compatible with 3Gb/s SAS controllers.
