12 TB SAS Nearline Drive

This 12 TB 3.5 inch internal hard drive uses a SAS 12 Gb/s interface and spins at 7200 RPM. It is built for Dell EMC PowerVault ME4 series storage systems. The drive suits administrators who need high-capacity nearline storage in a compatible Dell enclosure.

SAS 12 Gb/s Interface Limits

The SAS 12 Gb/s link sets the maximum bus throughput for this drive. Real-world sustained transfer rates will be lower and depend on the controller, cable length and system workload. The 7200 RPM spindle speed defines the rotational latency ceiling for random access patterns.

Bare Drive Build and Connector Implications

The unit ships as a bare drive without a carrier or mounting rails. Installation requires a 3.5 inch drive bay and a compatible SAS backplane or cabling. The standard SAS connector handles both data and power, so no separate power lead is needed.Buyers who want a hot-plug carrier or a different form factor must source those separately.

Questions about this item

Should I pick the 12TB version or a smaller capacity for my storage array?

The 12TB model provides the highest single-drive capacity in this series, reducing the number of bays needed for large datasets.

What does the 7200 RPM spindle speed deliver in a live server?

A 7200 RPM spindle yields consistent throughput for sequential workloads such as backup, archive and video surveillance recording.

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

The SAS 12Gb/s link caps burst transfers at 12Gb/s, while sustained speeds are governed by the 7200 RPM mechanical performance.
