Dell Enterprise 400GB SAS SSD

This Dell Enterprise solid-state drive delivers 400GB of storage through a 12Gbps SAS interface in a 2.5-inch form factor. It is supplied new with an R Series caddy included for direct mounting in compatible drive bays. The drive suits servers and storage arrays that require consistent enterprise-grade flash performance.

Sustained enterprise workload behaviour

The SAS 12Gbps interface supports steady throughput for mixed read and write workloads typical of database and virtualisation tiers. Enterprise flash endurance is designed to maintain performance across extended duty cycles without the thermal throttling seen in consumer drives. Workloads with high queue depths benefit from the dual-port SAS topology.

Installation and common issues

The included R Series caddy aligns with Dell PowerEdge and compatible backplanes for tool-less insertion. Installers must verify that the host controller and backplane support 12Gbps SAS signalling to avoid link-speed negotiation down to 6Gbps. Firmware compatibility should be confirmed against the server vendor's qualified hardware list before deployment.

Questions about this item

How much power does the 400GB SAS drive draw during continuous operation?

The 2.5 inch SSD has no moving parts, so its power draw stays low even when the 12Gbps link runs all day.

What controller or backplane must I already have to use the 12Gbps SAS interface?

A SAS host bus adapter or RAID card with a 12Gbps wide port and a 2.5 inch drive bay that accepts the included R Series caddy.

Will the 12Gbps SAS SSD negotiate down to 6Gbps on my older backplane?

Yes, the SAS link auto-negotiates, so the drive will run at 6Gbps on a 6Gbps backplane while keeping full 400GB capacity.
