Enterprise SAS Drive

This Seagate Enterprise Capacity 3.5 V.5 drive delivers 6TB of storage through a SAS 12Gb/s interface. It is built for servers and storage arrays that require a dual-port enterprise connection. The 7200 RPM spindle and 256MB cache support sustained throughput in multi-user environments.

Thermals and Power

The bare drive operates within standard 3.5 inch form factor limits for continuous 24x7 workloads. Enterprise firmware manages thermal thresholds and power states during heavy sequential and random access patterns. Acoustic output is tuned for rack density rather than desktop quietness.

Workload Rating

A 550TB per year workload rating supports write-intensive applications such as video surveillance, backup targets and object storage. The 2 million hour MTBF figure reflects validation for non-stop operation. Conventional magnetic recording technology underpins consistent performance without shingled write penalties.

Questions about this item

How do I install the ST6000NM0095 in a server and which step is often missed?

Mount the 3.5 inch drive in a SAS hot-swap bay or caddy, connect the SAS 12Gb/s data and power cables, then configure the drive in the RAID controller BIOS before the OS sees it.

What maintenance or replacement will the ST6000NM0095 need during its service life?

Plan for drive replacement once the 550TB per year workload rating is approached, and monitor SMART reallocated-sector counts during 24x7 operation.

What limit appears first when the ST6000NM0095 runs sustained writes?

The 7200 RPM rotational speed and 4.16ms average latency set the sustained throughput ceiling before the 256MB cache fills.
