1 TB 7200 RPM SAS 6Gb/s 2.5" drive

This 1 TB hard drive spins at 7200 RPM and connects through a SAS 6Gb/s interface in a 2.5 inch small form factor. It is built for server and storage arrays that need consistent throughput and enterprise-class reliability. The midline design balances capacity with cost for bulk data workloads.

Server and storage array deployments

The drive suits administrators expanding HP ProLiant or compatible SAS backplanes where hot-plug carriers are used. It is not intended for desktop PCs or laptops that lack a SAS controller, nor for environments that require solid-state latency or higher spindle speeds.

SAS 6Gb/s interface

The SAS 6Gb/s interface determines whether the drive can be used in the target backplane or controller. Verify that the host system supports 6 Gb/s SAS signalling and the correct 2.5 inch carrier before purchase.

Questions about this item

What capacity does the 652749-B21 provide for a server build?

The 652749-B21 is a 1 TB midline SAS drive designed for 2.5 inch server bays.

How does the 7200 RPM spindle speed affect real-world server workloads?

At 7200 RPM the drive delivers consistent throughput for transaction-heavy applications and mixed read-write workloads.

What does the SAS 6Gb/s interface limit in an actual chassis?

The SAS 6Gb/s link caps the maximum burst transfer rate at 6 Gbit/s, so sustained throughput will not exceed that ceiling.
