  • 4 TB capacity stores large datasets

  • 12 Gb/s SAS interface connects to enterprise controllers
  • 128 MB cache buffers heavy random I/O
  • 5 inch form factor fits standard drive bays

Enterprise SAS Drive

The Seagate ST4000NM0034 is a 4 TB hard drive built for enterprise storage arrays. It spins at 7200 RPM and connects through a 12 Gb/s SAS interface. The 3.5 inch form factor and 128 MB cache support sustained workloads in RAID environments.

Server Builders Only

This drive suits administrators deploying high-capacity nearline storage in servers or external JBODs that accept SAS connections. Workstations or laptops without a SAS host bus adapter cannot use it. Buyers needing a simple desktop upgrade should look elsewhere.

12 Gb/s SAS Interface

The single specification that decides fit is the SAS interface running at 12 Gb/s. Your backplane or controller must support this exact protocol and speed. Without a compatible SAS connection the drive will not function.

Questions about this item

Should I choose the 4 TB model or a different capacity for my storage array?

This model provides 4 TB of raw capacity; select it when your array requires that exact volume and 7200 RPM performance.

What does the 7200 RPM speed mean for everyday server workloads?

The 7200 RPM spindle delivers consistent throughput for sequential reads and writes in enterprise storage workloads.

How does the 12 Gb/s SAS interface limit real-world transfer rates?

The SAS 12 Gb/s link caps sustained transfers at the interface ceiling, so actual throughput depends on the controller and drive firmware.
