Dell 4TB SAS server drive

This Dell 400-ALRT is a 4TB internal hard drive built for 24x7 enterprise storage workloads. It uses a Near Line SAS interface running at 12Gb/s and spins at 7200 RPM. The drive ships new in a bare-drive package with a hot-plug carrier for 13th generation systems. It targets administrators expanding capacity in compatible Dell PowerEdge servers.

Compatibility check before ordering

Verify that your server or storage array accepts 3.5 inch Near Line SAS drives with a 12Gb/s interface. The supplier lists specific PowerEdge models including R230, R330, R430, R530, R630, R730, R730xd, R930, T330, T430, T530, T630 and PowerVault MD1220, MD1420, MD3420. Ensure an empty hot-plug bay and a supported backplane are available. Buyers needing a different interface or form factor cannot use this drive.

Build quality and daily implications

The unit weighs approximately 2.50 lb and carries RoHS environmental certification. Its hot-plug tray allows insertion or removal while the system runs, reducing downtime during maintenance. The carrier is designed for 13th generation Dell servers, so the drive seats securely in those chassis. Retail or OEM packing may vary, but the drive itself is new and rated for continuous enterprise duty cycles.
