Dell 391KC 8TB Nearline SAS Drive
The Dell 391KC is an 8TB 3.5-inch nearline SAS hard drive spinning at 7200 RPM. It is built for desktop or server storage arrays that require high-capacity bulk storage with a 12Gb/s SAS interface.
Verify SAS Controller and Bay Compatibility
Before ordering confirm that your system has a SAS host bus adapter or RAID controller with a free 12Gb/s port. You also need an available 3.5-inch drive bay and the correct power and data cables for a bare drive.
Thermals Noise and Power in Normal Use
As a 7200 RPM mechanical drive it generates noticeable vibration and audible seek noise during heavy workloads. Typical power draw rises during spin-up and sustained transfers so ensure your chassis airflow can handle the additional heat.

Domande su questo articolo
Does the Dell 391KC 8TB 3.5" SAS drive ship with a mounting tray or cables, or must they be sourced separately?
The drive is supplied as a bare unit without a tray or cables; a compatible SAS backplane and power lead are required for installation.
How do I decide between the 12Gb/s SAS interface and the 7200 RPM spindle speed for my workload?
The 12Gb/s SAS link sets the maximum data-transfer ceiling, while 7200 RPM governs rotational latency; together they suit nearline storage that balances throughput with capacity.
What does the 12Gb/s transfer rate mean for real-world throughput once the drive is in a server?
The 12Gb/s figure is the interface peak; sustained read and write speeds will be lower and depend on the controller, queue depth and the 7200 RPM mechanical limits.
