Enterprise bulk-data drive

The Seagate Constellation ES.3 ST4000NM0023 is a 4TB 3.5-inch internal hard drive built for 24x7 enterprise storage arrays. Its SAS 6Gb/s interface and 7200 RPM spindle suit servers and storage appliances that prioritise capacity density and predictable throughput.

SAS 6Gb/s interface requirement

This drive connects only to controllers or backplanes that support SAS 6Gb/s; it will not operate on SATA-only ports. Verify your host bus adapter or RAID card provides native SAS signalling before purchase.

Standard 3.5-inch bay install

The bare drive fits any 3.5-inch tray using the four bottom or side mounting holes; no rails or adapters are included. Common issues are forgetting a SAS-compatible cable and neglecting to enable the drive in the RAID BIOS after physical installation.
