Enterprise 960 GB SATA SSD

The HPE P40503-B21 is a 2.5 inch internal solid state drive built for enterprise workloads. It delivers 960 GB of capacity using 3D NAND and a DRAM cache behind a SATA III interface. Mixed-use rating and 3.4 DWPD make it suited for read-write intensive server applications.

2.5 inch form factor with standard SATA connectors

The drive fits common 2.5 inch drive bays and backplanes using the familiar SATA data and power connectors. DRAM cache helps sustain performance during mixed workloads while the 3D NAND construction supports the rated endurance. No additional mounting hardware is described in the specifications.

Thermals power and acoustics in normal use

As a solid state device with no moving parts the drive operates silently. Power draw scales with the 1900 MBps sequential read and 1200 MBps sequential write activity levels typical of mixed-use server traffic. Thermal output remains low enough for standard server airflow without special cooling requirements.

Questions about this item

Will this 2.5" SATA drive fit in my server's hot-swap bay?

The drive uses the standard 2.5" form factor with a SATA III interface, matching common enterprise hot-swap trays.

What does the 3.4 DWPD rating mean for daily write workloads?

It guarantees you can write the full 960 GB capacity 3.4 times every day for the warranty period without exceeding the endurance spec.

Does the DRAM cache improve performance for mixed-use server tasks?

Yes, the onboard DRAM cache helps sustain the rated 1900 MB/s reads and 1200 MB/s writes during random mixed-use I/O.
