Capacity and interface

The Dell RWR8F is a 2.4TB internal hard drive with a SAS 12Gb/s interface and a 2.5-inch form factor. It targets enterprise and data-centre environments that require fast data access and high storage capacity in a compact drive bay.

Sustained workload behaviour

A 10000 RPM spindle speed and 256MB cache enable the drive to maintain consistent throughput during prolonged read and write operations. The mechanical design supports continuous duty cycles typical of database, virtualization and analytics workloads without the performance drops seen in burst-oriented consumer drives.

SAS 12Gb/s practical limits

The SAS 12Gb/s link provides a 12Gb/s signalling rate, but real-world throughput is constrained by the 10K rotational speed and the 512e sector format. The interface supports dual-port connectivity for path redundancy, yet the single-actuator mechanism caps maximum sustained transfer below the theoretical bus ceiling.

Questions about this item

How much power and heat does the 2.4TB 10000 RPM SAS drive produce during continuous operation?

The 2.5" 10K spindle draws more power and generates more heat than slower desktop drives; ensure your chassis airflow and power budget can sustain a 12Gb/s enterprise SAS disk running all day.

What controller or backplane must I already have for this RWR8F drive to work?

You need a SAS host bus adapter, RAID controller or server backplane that supports 12Gb/s SAS signalling; the 512e sector format also requires an OS or controller that handles 512-byte emulation.

Will this 12Gb/s SAS disk work alongside my older 6Gb/s SAS drives in the same enclosure?

Yes, the 12Gb/s interface negotiates down to 6Gb/s when paired with legacy SAS drives or backplanes, so the 2.4TB 10K unit can share a domain with older SAS hardware.
