6 TB SAS drive for enterprise storage

The Dell 400-ALCK is a 3.5-inch internal hard drive with a 6 TB capacity and a 12 Gb/s SAS interface. It spins at 7200 RPM and is built to enterprise-class specifications for continuous operation in compatible servers and storage arrays.

Replaces lower-capacity or slower SAS drives

The jump is worth it when a system needs more raw capacity on the same SAS backplane or when a 7.2 K RPM spindle improves throughput over 5.4 K alternatives. It fits 13G Dell platforms that accept the ST6000NM0095 mechanism without requiring a protocol change.

Fits 3.5-inch SAS bays with 12 Gb/s controllers

The drive needs a SAS host bus adapter or RAID controller that supports 12 Gb/s speeds and a chassis with 3.5-inch drive bays and appropriate power connectors. It frees up bay count by delivering 6 TB per slot, reducing the number of spindles required for a given volume target.

Questions about this item

Will the 3.5'' SAS drive fit a standard 3.5-inch drive bay in a 13G Dell server?

Yes, the 3.5'' form factor matches standard 3.5-inch hot-plug bays used in 13G Dell PowerEdge servers; the SAS connector aligns with the backplane.

How is the 400-ALCK installed in a hot-plug tray, and what step is often missed?

Slide the drive into the carrier until the SAS connector seats firmly on the backplane, then lock the lever; the step often missed is fully engaging the lever latch.

When should the 6 TB 7200 RPM SAS drive be replaced in a RAID array?

Replace the drive when SMART reallocated-sector counts rise or the RAID controller flags predictive failure; rebuild the array promptly after swapping.
