Silver 3.5 inch bare hard drive with exposed circuit board

Seagate

Seagate Constellation ES.3 ST4000NM0033 4TB 7200RPM 128MB 3.5" SATA internal hard drive

SKU CH-VMEJ-4NQZ1

A 4 TB 3.5-inch SATA drive spinning at 7200 RPM with a 128 MB cache for desktop storage

  • 4 TB capacity for large data storage
  • 7200 RPM spindle speed for responsive performance
  • 128 MB cache to accelerate frequent reads
  • SATA 6 Gb/s interface for broad compatibility
  • 5 inch form factor fits standard drive bays

Enterprise Capacity Drive

The Seagate Constellation ES.3 ST4000NM0033 is a 4TB 3.5-inch internal hard drive spinning at 7200RPM with a 128MB buffer. It connects via a SATA 6Gb/s interface and is supplied as a bare drive only. The unit weighs 2.0 pounds and carries a one-year manufacturer warranty. It is built for continuous operation in desktop and server environments.

Suited For Bulk Storage

This drive suits users who need high-capacity mechanical storage for backups, archives, or bulk data on a standard SATA port. It is not for buyers who want solid-state latency or a drive pre-mounted in a carrier or caddy. Builders requiring a smaller physical form factor or a different interface protocol should look elsewhere.

Deciding Specification

The single specification that decides fit is the SATA 6Gb/s interface combined with the 3.5-inch form factor. Your system must provide a standard SATA data connector and a 3.5-inch drive bay with appropriate power. Without these, the drive cannot be installed or used.

Questions about this item

How do I install the ST4000NM0033 3.5" SATA drive and what step is often missed?

Mount the 3.5 inch drive in a bay, connect the SATA data cable to a 6Gb/s port and attach the SATA power connector; the step often missed is ensuring the motherboard SATA controller is set to AHCI mode in BIOS for full 6Gb/s throughput.

What maintenance or replacement will the Constellation ES.3 4TB drive need later?

No routine maintenance is required; plan to replace the drive once its rated workload or MTBF limit is reached, or if SMART attributes report reallocated sectors or declining health.

What limit appears first on the ST4000NM0033 under sustained 7200RPM write workloads?

The 128MB cache fills quickly during sustained writes, so the drive then throttles to the native media transfer rate of the 7200RPM platters, which becomes the throughput bottleneck.
