Enterprise bulk storage

The Seagate Exos 7E10 ST6000NM020B is a 6TB 3.5 inch internal hard drive built for enterprise storage workloads. It spins at 7200 RPM with a 256MB cache and connects through a SAS 12Gb/s interface. The drive is designed for continuous 24x7 operation in mainstream data centre applications. Its average latency is 4.16ms.

Replaces slower or smaller enterprise drives

This model upgrades from lower-capacity or lower-RPM enterprise SAS drives when higher throughput and larger bulk storage are required. The jump is worth it for workloads that need sustained performance and enhanced reliability for data protection in a 24x7 environment. The 12Gb/s SAS interface supports high-performance mainstream data centre deployments.

Verify SAS controller and bay compatibility

Confirm your server or storage array has a SAS 12Gb/s controller and an available 3.5 inch drive bay before ordering. The physical dimensions are 147.00mm length, 101.85mm width and 26.11mm height. Ensure the system supports enterprise-class drives and provides adequate cooling for continuous operation.

Questions about this item

What are the exact dimensions of the 3.5" drive so I can confirm it fits my bay?

The drive measures 147.00mm long, 101.85mm wide and 26.11mm high, matching the standard 3.5" form factor.

How is the SAS 12Gb/s drive installed, and what step is often missed?

Mount the drive in a 3.5" bay, attach the SAS data and power cables to a compatible controller, then configure the drive in the controller BIOS or OS disk utility so the 6TB volume appears.

What maintenance or replacement should I plan for with this 7200 RPM enterprise drive?

Monitor SMART attributes and the 4.16ms average latency; replace the drive if reallocated sectors rise or if it reaches the rated 24x7 workload limit.
