Enterprise capacity drive
The Seagate Constellation ES.3 ST4000NM0023 is a 4TB 3.5-inch internal hard drive built for enterprise storage arrays. It spins at 7200 RPM with a 128MB cache and connects through a SAS 6Gb/s interface. The drive is supplied in refurbished condition.
Suits bulk-data arrays, not desktop boot
This drive suits administrators expanding RAID sets, backup targets or cold-storage tiers where high capacity and sustained write endurance matter. It is not for builders who need a SATA-only controller, a 2.5-inch form factor, or a consumer warranty bundle.
SAS 6Gb/s interface decides fit
The SAS 6Gb/s interface is the single specification that determines compatibility; the drive requires a backplane or controller that supports SAS signalling. A SATA-only host bus adapter cannot negotiate the link, so the drive will not be recognised.

Fragen zu diesem Artikel
Should I pick the 4TB model or a different capacity for my storage array?
This specific unit is the 4TB capacity; other capacities are separate part numbers not covered by this listing.
What does the 7200 RPM speed mean for daily workloads?
The spindle rotates at 7200 RPM with a 4.16ms average latency, delivering consistent throughput for bulk-data enterprise applications.
Will the SAS 6Gb/s interface limit performance on my controller?
The drive uses a SAS 6Gb/s interface, so the link caps at 6Gb/s; actual throughput depends on your controller and system configuration.
