Dell 400-AATJ 3 TB SAS drive

The Dell 400-AATJ is a 3 TB desktop internal hard drive built for systems that use a SAS interface. Its 3.5-inch form factor fits standard drive bays in workstations and servers. The spindle spins at 7.2K RPM and the drive connects at 6 Gb/s, making it suitable for bulk storage workloads. Condition is new and packing may vary between retail and OEM.

Non hot-swap SAS integration

This unit is non hot-swap, so the host must be powered down before installation or removal. A free 3.5-inch bay, a compatible SAS backplane or controller, and matching power and data cables are required. The drive adds high-capacity storage without occupying a hot-swap tray slot, leaving those bays available for removable media. Buyers needing hot-swap capability or a different interface should consider other models.

Questions about this item

How long does the 7.2K spindle speed sustain write throughput before thermal throttling?

The 7.2K spindle speed maintains its rated throughput for typical desktop workloads; sustained heavy writes will eventually hit the drive's internal thermal limit and reduce speed.

What noise and heat levels does the SAS interface produce during all-day operation?

The SAS interface itself is silent; the 7.2K mechanism generates moderate whir and warm-case temperatures typical for a 3.5-inch desktop drive running continuously.
