The Seagate ST4000NM0023 is a 3.5 inch SAS hard drive that delivers 4TB of storage for servers, high-performance workstations, and data center racks.

With a spindle speed of 7200 RPM and a SAS interface that moves data at up to 6 Gb/s, it keeps throughput steady even when many users access the system at the same time. A 128 MB cache smooths out bursts of activity, supporting tasks such as virtualization, database queries, and large media transfers without noticeable slowdown.

This Constellation ES.3 model is built for nonstop service. Seagate pairs enhanced error correction with vibration control and rates the drive for up to 1.4 million hours MTBF, giving administrators confidence when deploying it in multi-drive RAID arrays or critical backup sets.

PowerChoice technology allows the drive to lower power consumption during idle periods, which reduces heat and contributes to lower operating costs in dense server cabinets. The standard 3.5 inch form factor installs easily in most enterprise drive bays or high-performance workstations, so expansion is straightforward.

Whether you need bulk capacity for a cloud node, a dependable target for nightly backups, or additional space for a media workstation that stays on around the clock, the Seagate Constellation ES.3 provides a balanced mix of speed, capacity, and durability.

Highlights:
  • 4 TB storage capacity supports large databases and bulk file archives
  • 7200 RPM rotational speed delivers access that is both fast and consistent
  • SAS interface with 6 Gb/s bandwidth integrates with modern server backplanes
  • 128 MB cache improves responsiveness during heavy multitasking and RAID rebuilds
  • 3.5 inch form factor fits standard server and workstation drive trays
  • PowerChoice feature lowers power draw during idle periods to aid cooling
  • Rated for up to 1.4 million hours MTBF for round-the-clock reliability
  • Optimized for RAID and other enterprise storage architectures
