2 TB SAS Enterprise Drive

The Seagate Constellation ES.3 ST2000NM0023 is a 3.5-inch internal hard drive with a 2000 GB capacity and a 7200 RPM spindle speed. It connects via a SAS 6Gb/s interface and includes a 128 MB cache buffer. The unit is supplied new with zero powered-on hours.

Built for Servers and Arrays

This drive suits storage servers, RAID arrays and backup appliances that accept 3.5-inch SAS devices. It is not for systems that lack a SAS host bus adapter or backplane. Desktop motherboards and consumer enclosures without SAS support cannot use this drive.

SAS 6Gb/s Interface Decides Fit

The single specification that determines compatibility is the SAS 6Gb/s interface. The drive requires a controller or backplane that speaks the SAS protocol at 6 Gbit/s. Without that connection, the drive will not function.

Questions about this item

Does my system need a SAS 6Gb/s controller to use this ST2000NM0023 drive?

Yes, the drive uses a 3.5" SAS 6Gb/s interface and requires a compatible SAS controller or HBA to operate.

Can I mix this 7200RPM SAS drive with older SAS drives running at 3Gb/s on the same controller?

The drive supports 6Gb/s SAS; when connected to a 3Gb/s backplane or controller it will negotiate down to the slower link speed.

How can I confirm the drive is healthy after installation given it shows zero hours?

Run a SMART self-test and verify the power-on hours counter reads zero, matching the zero-hours condition stated for this unit.
