6 TB Nearline SAS Drive

The Dell 400-ALCM is a 6 TB 3.5" Nearline SAS hard drive spinning at 7200 RPM for bulk storage in servers and storage arrays. It uses a 12Gb/s SAS interface and ships as a bare drive with a hot-swap tray for tool-less replacement in compatible bays.

Compatibility Checks

Verify that your backplane or controller supports 12Gb/s SAS and can supply adequate power for a 3.5" nearline drive. Confirm the chassis accepts hot-swap trays of this form factor and that your RAID or HBA firmware recognises the 6 TB capacity.

Sustained Workload Behaviour

Designed for continuous operation, the 7.2K spindle delivers steady throughput for sequential workloads such as backup, archiving and media repositories. The Nearline class prioritises consistent latency over burst speed, making it suited to always-on environments rather than high-IOPS transactional databases.

Questions about this item

Does the 400-ALCM drive ship with a mounting tray or cables?

The drive is supplied as a bare unit without a tray or cables; a compatible hot-swap carrier and SAS data cable must be sourced separately.

Which SAS 12Gb/s 3.5" capacity should I choose for a Dell PowerEdge bay?

This model provides 6TB at 7200 RPM; select it when you need that exact capacity and speed combination for the bay.

What sustained throughput can I expect from the 12Gb/s interface in a RAID array?

The 7200 RPM platters typically deliver sequential reads around 200 MB/s, so the 12Gb/s link will not be the bottleneck in a RAID set.
