1.2 TB 10K SAS drive for Dell servers

This 2.5-inch hard drive delivers 1.2 TB of storage with a 10K rotational speed over a 12 Gb SAS interface. It is supplied as a new drive kit intended for direct installation in compatible Dell PowerEdge systems. The SAS connection provides dual-port reliability for enterprise workloads.

Suits Dell R640 R740 R740XD R940 C6420 bays

The drive kit fits the 2.5-inch bays of the listed PowerEdge models and is built for environments that demand consistent 10K performance. It is not for users who need higher capacity per drive, SATA-only controller support, or 3.5-inch form-factor compatibility.

12 Gb SAS interface decides controller fit

The drive requires a 12 Gb SAS backplane or HBA to operate at its rated speed and dual-port capability. Connecting it to a 6 Gb SAS or SATA-only controller will limit performance or prevent detection, so verify the host interface before purchase.

Questions about this item

How do I install the 400-AUXJ 2.5" SAS drive in a Dell PowerEdge R740 and which step is often missed?

Slide the drive into a 2.5" hot-swap bay until the carrier clicks, then verify the 12Gb SAS link in the RAID controller BIOS — the step often missed is seating the carrier latch fully so the SAS connector engages.

What maintenance or replacement will the 1.2TB 10K SAS drive need over its service life?

Plan to replace the drive after the rated workload limit is reached or if SMART attributes report reallocated sectors; no field-serviceable parts exist inside the sealed helium enclosure.

What limit appears first on the 400-AUXJ during sustained 12Gb SAS writes?

The 10K RPM spindle caps sustained throughput before the 12Gb SAS bus saturates, so sequential write speed plateaus at the mechanical media rate.
