Enterprise SAS drive

This Seagate Constellation ES.3 is a 2 TB 3.5-inch internal hard drive built for server environments. It spins at 7200 RPM, connects through a SAS 6 Gb/s interface and carries a 128 MB cache. The unit is supplied new and intended for continuous operation in enterprise storage arrays.

Who should consider this

IT teams deploying or expanding RAID sets, backup targets or near-line archives in servers and external enclosures with SAS backplanes will find the capacity and rotational speed appropriate. Workstations or desktops that only offer consumer drive bays or lack a compatible SAS host adapter cannot accommodate this drive.

Deciding specification

The 3.5-inch SAS 6 Gb/s interface is the single attribute that determines whether the drive fits your infrastructure; verify that your controller and backplane support this connection before purchase.

Questions about this item

Will the 3.5-inch SAS drive fit a standard server drive bay?

The 3.5-inch form factor matches standard enterprise drive bays and the SAS interface uses the combined power and data connector.

What is the correct way to connect the SAS interface during installation?

Attach the SAS cable to the 6Gb/s port on the controller and ensure the drive receives power through the same connector.

When should the 128MB cache drive be replaced in a server array?

Monitor SMART attributes for reallocated sectors and plan replacement once the drive reaches its rated workload limit.
