HPE 2 TB SAS Server Drive

The HPE 507616-B21 is a new 3.5-inch internal hard drive with a 2 TB capacity and a 7200 RPM spindle speed. It connects through a 6Gb/s SAS interface and is built for enterprise-class storage where reliability and data integrity are crucial. The drive fits standard LFF bays and supports hot-swap operation.

Suited for high-transaction server workloads

This drive suits administrators who need a midline SAS drive for hosting high-transaction applications in HPE ProLiant or compatible servers. It is not for systems that lack a SAS backplane or controller, nor for users who require a 2.5-inch form factor or a different capacity point.

Deciding spec: 6Gb/s SAS interface

The single specification that decides fitment is the 6Gb/s SAS interface; the host must provide a matching SAS port and backplane. Without that connection the drive cannot be used, regardless of its capacity or spindle speed.

Questions about this item

Should I choose the 2 TB 3.5" 7200 RPM SAS drive or a 2.5" alternative for my server?

The 3.5" form factor fits standard LFF bays and is rated for hot-swap use in HPE servers. The 2.5" SFF version suits denser chassis but requires a different carrier.

What does the 7200 RPM spindle speed mean for real-world throughput in a transaction-heavy workload?

At 7200 RPM the drive delivers consistent sequential and random I/O for database and email workloads, matching the performance profile HPE specifies for its Midline enterprise drives.

How does the 6Gb/s SAS interface limit the maximum transfer rate when connected to a 12Gb/s controller?

The drive negotiates at 6Gb/s, so peak throughput is capped at that link speed regardless of the controller's higher capability.
