Enterprise SAS Drive

The Seagate Constellation ES.3 ST2000NM0023 is a 2000GB internal hard drive with a SAS 6Gb/s interface. It spins at 7200RPM and includes a 128MB buffer. The 3.5in form factor fits standard enterprise bays. It is supplied as a bare drive only.

Not For Desktop Use

The manufacturer highlights state the capacity is not for desktops. This drive suits servers and storage arrays that require SAS connectivity. Builders without a SAS controller or backplane cannot install it. Buyers needing a simple desktop storage upgrade should look elsewhere.

SAS 6Gb/s Interface Decides Fit

The single specification that determines compatibility is the SAS 6Gb/s interface. Your system must provide a SAS port or compatible HBA to use this drive. Without that connection the 7200RPM mechanics and 128MB cache remain inaccessible. Verify the host interface before purchase.

Questions about this item

Is the 2000GB capacity the only option for the ST2000NM0023?

Yes, the ST2000NM0023 is supplied as a single 2000GB model with a 128MB buffer and 7200RPM speed.

What does the 7200RPM speed deliver in a server chassis?

The 7200RPM spindle provides consistent throughput for nearline workloads, supported by the 128MB cache to smooth burst traffic.

How does the SAS 6Gb/s interface limit real-world transfer rates?

The SAS 6Gb/s link caps the interface at 6Gb/s, so sustained reads and writes cannot exceed that ceiling.
