Enterprise Server Storage

This HPE 872479-B21 is a 1.2 TB SAS hard drive spinning at 10000 RPM with a 12Gb/s interface in a 2.5 inch form factor. It is built for servers that need high-performance enterprise storage for mission-critical and I/O-intensive applications. The drive includes hot-swap capability and digitally signed firmware for security.

Suited For Transactional Workloads

It suits administrators who need improved server response times and accelerated data transfer speeds for demanding application workloads. The drive is backed by extensive qualification testing for reliability in enterprise environments. It is not for systems that lack a SAS 12Gb/s controller or 2.5 inch drive bays. Buyers who need larger capacities should consider other models in the product line.

SAS 12Gb/s Interface Decides Fit

The single specification that determines compatibility is the SAS 12Gb/s interface. The host system must provide a matching SAS controller and backplane to operate this drive. Without that specific interface connection, the drive will not function in the server.

Questions about this item

How does the 10000 RPM spindle speed affect sustained write performance?

The 10000 RPM spindle enables high IOPS for I/O-intensive workloads, though sustained throughput is ultimately limited by the SAS 12Gb/s interface bandwidth.

What are the thermal and acoustic characteristics during continuous operation?

Designed for enterprise server bays, the 2.5" form factor relies on chassis airflow for cooling; no standalone acoustic or power-draw figures are published for this drive.

Which controller or backplane is required to use the SAS 12Gb/s interface?

A 12Gb/s SAS HBA, RAID controller, or server backplane with matching SAS connectors is needed; the drive will negotiate down to 6Gb/s on older links.
