Dell Enterprise 1TB Entry Server Hard Drive (400-ATJJ) – SATA 6Gb/s, 7200 RPM, CMR

The Dell Enterprise 1TB (400-ATJJ) is a 3.5-inch 7200 RPM SATA 6Gb/s server hard drive for Dell PowerEdge servers. It suits IT teams and resellers replacing failed drives or expanding RAID arrays with Dell-compatible storage. Dell firmware keeps PERC RAID and iDRAC health reporting fully supported.

Drop-in server storage matched to Dell hardware.

Avoiding Compatibility Warnings in Dell Servers

Dell PowerEdge servers and PERC RAID controllers work best with drives that carry Dell firmware. Non-qualified drives can trigger iDRAC warnings, lose health reporting or be flagged as unsupported in the array.

The Dell Enterprise 1TB is a Dell part designed for PowerEdge platforms, with SATA 6Gb/s connectivity and 7200 RPM operation. At 1TB, it is a cost-effective fit for smaller server builds, boot-and-backup roles and replacing older low-capacity drives.

Full Health Reporting in iDRAC and OpenManage

Dell firmware lets iDRAC and OpenManage monitor drive health and predictive failure, so replacements are planned rather than urgent.

Fast Replacement in Existing Arrays

Hot-plug kit (Dell part X7K8W carrier) lets you swap the drive into an existing RAID set and rebuild with minimal disruption.

Setup Instructions

How to Install the Dell Enterprise 1TB in a PowerEdge Server

1. Confirm the part is compatible with your PowerEdge model and drive bay type.
2. Fit the drive into a Dell carrier (if not already installed) and insert it into the bay.
3. Check iDRAC or the PERC controller to confirm detection and health status.
4. Rebuild the RAID set or create a new virtual disk, then verify the array is optimal.
