2TB Nearline SAS Drive for Array Storage

The Dell 400-ANWJ is a 2TB 2.5-inch nearline SAS hard drive spinning at 7200 RPM. It is built for servers and storage arrays that need high-capacity bulk storage with hot-swap capability. The 12Gb/s SAS interface connects directly to compatible controllers and backplanes. This drive suits administrators expanding existing SAS infrastructure.

Sustained Throughput on 7200 RPM Spindles

Under continuous workloads the 7200 RPM spindle delivers steady sequential bandwidth rather than burst-only peaks. Nearline firmware optimises write consistency for RAID rebuilds, backups and archival streaming. The SAS protocol maintains command queuing efficiency during long transfers. Performance scales with controller queue depth and stripe width.

12Gb/s SAS Interface Practical Limits

The 12Gb/s SAS link caps maximum theoretical throughput at the interface level. Real-world throughput depends on controller implementation, cable length and backplane topology. The drive operates at 3Gb/s average latency specification within the SAS domain. Compatibility requires a SAS HBA or RAID controller with 12Gb/s support.

Questions about this item

How much noise and heat does the 7200 RPM 2.5" drive produce when running all day?

The 2.5" nearline SAS drive spins at 7200 RPM, so it generates typical mechanical-drive noise and warmth for continuous operation.

What controller or backplane must I already have for this 12Gb/s SAS drive to work?

A SAS controller or backplane that supports 12Gb/s SAS is required; the drive uses a standard SAS connector and hot-swap tray.

Will the 400-ANWJ work alongside older 3Gb/s or 6Gb/s SAS drives in the same enclosure?

Yes, the 12Gb/s interface is backward compatible with 3Gb/s and 6Gb/s SAS links, so it can share an enclosure with older SAS drives.
