Enterprise bulk storage

The Seagate Constellation ES.3 ST3000NM0023 is a 3TB 3.5-inch internal hard drive built for 24x7 enterprise workloads. It spins at 7200 RPM with a 128MB cache and connects through a SAS 6Gb/s interface for predictable throughput in storage arrays.

Suited for RAID arrays and servers

This drive targets administrators who need reliable, high-capacity bulk storage in SAS environments. It is not for personal computers or workstations that lack a SAS controller, nor for builders who require SATA-only connectivity or boot drives for consumer motherboards.

Build integration notes

The bare drive measures 147.00mm long, 101.85mm wide and 26.10mm high, fitting standard 3.5-inch bays. A compatible SAS backplane or HBA is required, freeing SATA ports for other devices while delivering enterprise-grade error correction and super parity features.

Questions about this item

Does my system need a SAS 6Gb/s controller to use this ST3000NM0023 drive?

Yes, this enterprise drive requires a SAS 6Gb/s host bus adapter or RAID controller; it will not work with standard desktop SATA ports.

Can I run this 7200 RPM SAS drive alongside older SATA drives in the same server?

It can share a SAS backplane or expander with SATA drives, but each drive must connect to a SAS 6Gb/s port; direct SATA cabling is not supported.

How do I verify the ST3000NM0023 is healthy after installation?

Check SMART attributes for a health rating of at least 90%, confirm the 3TB capacity appears in the RAID utility, and listen for normal 7200 RPM operation.
