Enterprise SAS drive for 3.5" bays

The HGST Ultrastar 7K4000 is a new 3 TB internal hard drive built for enterprise storage arrays and servers. It spins at 7200 RPM with a 64 MB buffer and connects through a SAS interface in a standard 3.5-inch form factor. The 7K4000 series targets high-capacity nearline workloads where sustained throughput and drive density matter.

Ideal for SAS-based arrays.

Administrators expanding nearline storage, backup repositories or bulk-data pools will find the drive matches existing SAS infrastructure. Buyers whose host controllers or backplanes only provide other interfaces cannot use this unit without additional hardware. The 3.5-inch height fits standard enterprise drive bays and hot-swap carriers.

SAS interface determines compatibility

The single specification that decides fitment is the SAS drive interface. A system must present a native SAS connection or a compatible controller to communicate with this drive. No other interface is supported by the unit itself.

Questions about this item

How does the 7200 RPM spindle speed affect sustained write performance?

The 7200 RPM spindle speed provides consistent rotational latency for sustained write workloads, while the 64 MB cache buffers bursts to maintain throughput during heavy use.

What are the noise and heat characteristics when the 3.5" drive runs continuously?

The 3.5" form factor with 1" height allows standard enterprise airflow cooling; typical 7200 RPM operation produces audible seek noise and measurable heat requiring active chassis cooling.

What SAS host bus adapter or RAID controller is needed to connect this drive?

This drive uses a SAS interface and requires a compatible SAS host bus adapter or RAID controller with matching SAS connectors for operation.
