Product Identity

The Seagate Constellation ES ST2000NM0021 is a 2TB enterprise-grade hard drive built for 3.5-inch bays. It spins at 7200RPM and connects through a SAS 6Gb/s interface. This new unit suits servers and storage arrays that require consistent throughput and dual-port reliability.

Buyer Fit

IT teams managing RAID enclosures, backup appliances or near-line archives will match this drive to SAS backplanes and controllers. Buyers whose systems lack a SAS host bus adapter or backplane cannot install this drive and should select a model with the interface their hardware provides.

Deciding Specification

The SAS 6Gb/s interface is the single specification that determines compatibility. Only proceed when the target chassis and controller explicitly support this connection standard.

Pitanja o ovom artiklu

How much heat and power does the 7200RPM SAS drive produce when running continuously?

The 7200RPM SAS 6Gb/s drive is built for enterprise workloads and draws typical power for a 3.5-inch 2TB nearline drive; expect standard heat output for a 2.0-pound unit in a ventilated bay.

What host controller or backplane is needed to connect the 3.5-inch SAS 6Gb/s interface?

You need a SAS HBA, RAID card or server backplane with a 6Gb/s SAS port and a 3.5-inch drive bay that supplies 12 V and 5 V power.

Will the ST2000NM0021 work in an older 3Gb/s SAS backplane without speed loss?

The drive negotiates down to 3Gb/s on legacy SAS backplanes, so it functions normally but at the slower link rate of the older controller.
