SKU CH-09J0-HQ65K MPN ST6000NM0115

A 6 TB 3.5" enterprise hard drive spinning at 7200 RPM with 256 MB cache and a SATA interface for 24/7 server workloads

  • 6 TB capacity stores large enterprise datasets
  • 7200 RPM spindle speed delivers fast data access
  • 256 MB cache accelerates read and write operations
  • SATA 6Gb/s interface enables simple integration into RAID systems
  • Rated for 550 TB per year workload in 24x7 environments

6 TB enterprise hard drive

The DELL ST6000NM0115 is a 6 TB 3.5 inch internal drive built for 24x7 server and storage environments. It spins at 7200 RPM and includes a 256 MB cache to handle sustained enterprise workloads. The drive is designed for capacity-optimised multi-drive deployments where reliability is critical.

SATA III interface limits

The SATA III interface caps the maximum transfer rate at 6 Gb/s, which restricts peak throughput compared to faster protocols. The 512e sector format aids compatibility with legacy systems but does not remove the bandwidth ceiling. Workloads demanding higher sequential speeds will hit this hard bottleneck.

Standard 3.5 inch installation

The drive fits standard 3.5 inch drive bays and connects via SATA data and power cables. Installation is straightforward for technicians familiar with enterprise chassis. Misaligned mounting screws or loose SATA connectors are the most common causes of detection failures.

Questions about this item

Should I choose the 6 TB version or a smaller capacity for my storage array?

The 6 TB model provides the highest raw capacity in this drive family, reducing the number of bays needed for a given total volume.

What does the 7200 RPM rating deliver in an actual server chassis?

It sustains the throughput required for nearline workloads rated up to 550 TB per year while keeping latency low for RAID rebuilds.

How does the SATA III interface limit real-world transfer speed?

The 6 Gb/s link caps sequential throughput at the SATA III maximum, so the drive cannot exceed that ceiling even with its 256 MB cache.
