Enterprise Nearline Storage

The Seagate Constellation ES ST2000NM0001 is a 2TB 3.5-inch internal hard drive built for continuous operation in server environments. It connects via a SAS 6Gb/s interface and spins at 7200 RPM with a 64MB cache to handle sustained workloads.

Suited For And Not Suited For

This drive suits administrators deploying nearline storage arrays that demand 24×7 reliability and the dual-port SAS protocol. Buyers who need a different interface protocol or a drive not rated for constant enterprise duty should look elsewhere.

Deciding Specification

The SAS 6Gb/s interface is the single specification that determines compatibility; the system backplane or controller must support this exact connection for the drive to function.

Questions about this item

What controller or backplane do I need so the ST2000NM0001 can communicate with my server?

The drive uses a SAS 6Gb/s interface, so it requires a compatible SAS HBA, RAID controller or SAS backplane to operate.

Will the 3.5-inch Constellation ES fit in the same drive bays as my existing 3.5-inch SAS drives?

Yes — it shares the standard 3.5-inch form factor, so it mounts in any enterprise bay or tray designed for 3.5-inch SAS drives.

How can I confirm the ST2000NM0001 is running at its rated speed after installation?

Check that the system reports a 7200 RPM spindle speed and a 6Gb/s SAS link rate; the drive's average latency is 4.16ms.
