Enterprise Storage Drive

The Dell 400-ALCR is a 6TB 3.5" internal hard drive built for enterprise storage systems. It uses a SAS 12Gb/s interface and spins at 7200 RPM to handle demanding workloads. The drive is sold as a bare unit in new condition.

Hot-Swap SAS Integration

This drive fits 3.5" hot-swap bays in compatible storage arrays such as the Dell PowerVault MD3400. The SAS 12Gb/s interface provides dual-port connectivity for path redundancy. No separate carrier is included with the bare drive packaging.

Sustained 7200 RPM Operation

The spindle maintains 7200 RPM continuously to deliver consistent throughput for sequential and random access patterns. Average latency is rated at 3Gb/s for predictable response times. Dual-port SAS helps maintain availability during heavy I/O loads.

Questions about this item

How much sustained throughput can the 12 Gb/s SAS link actually deliver?

The drive spins at 7200 RPM and uses a 12 Gb/s SAS interface; real-world sustained transfer will be limited by the mechanical media, not the link speed.

What noise and heat should I expect when this drive runs continuously in an array?

As a 7200 RPM enterprise SAS drive, it produces typical mechanical noise and heat for near-line storage; ensure your chassis provides adequate airflow.

Which controller or backplane do I need to connect this 3.5" SAS drive?

It requires a 12 Gb/s SAS HBA, RAID card or backplane with 3.5" drive bays; the drive is hot-swappable in compatible Dell PowerVault MD3400 systems.
