300 GB 10K SAS drive

The HPE P40430B21 is a 300 GB 2.5-inch internal hard drive spinning at 10000 RPM over a SAS 12Gb/s interface. It is built for servers and storage arrays that need fast, reliable access to transactional data.

Replaces slower 7200 RPM SAS drives

Moving from a 7200 RPM SAS drive to this 10K model cuts latency for random read and write workloads. The jump is worth it when databases, virtualization hosts or email servers hit I/O bottlenecks on lower-speed spindles.

Fits 2.5-inch SFF bays with SAS backplanes

The small form factor slides into standard 2.5-inch drive bays and connects directly to 12Gb/s SAS backplanes or controllers. It frees 3.5-inch slots for higher-capacity archive drives while keeping performance tiers on the same interface.

Questions about this item

Will the 2.5" SFF form factor fit my server drive bay?

The drive uses a 2.5-inch small form factor designed for SFF bays in compatible HPE servers and storage systems.

What is the correct way to seat the SAS connector during installation?

Slide the drive into the bay until the SAS interface engages the backplane, then secure the mounting screws or latch to prevent vibration.

When should I expect to replace this 10000 RPM drive under heavy workloads?

Enterprise 10000 RPM SAS drives typically reach end of life after three to five years of continuous operation depending on workload intensity.
