HPE P40503‑B21 960GB 2.5″ SATA Mixed‑Use SSD

Overview

The HPE P40503‑B21 is a 960 GB internal solid state drive designed for enterprise and server storage environments. It is a 2.5‑inch SATA mixed‑use SSD deployed in HPE ProLiant rack and tower servers where balanced performance, endurance, and reliability are critical for active database, virtualization, and mixed workload applications. This drive provides a storage tier above traditional HDDs with improved latency and throughput characteristics suitable for production server use.

Engineered with a SATA 6 Gb/s interface and 2.5″ small form factor, this drive integrates into hot‑swap drive bays using a basic carrier (BC), enabling serviceability without powering down systems. Firmware is digitally signed and certified for compatibility with HPE server generations Gen10 Plus, Gen11, and Gen12 platforms.

The mixed‑use endurance class allows sustained read/write activity typical of server workloads, offering improved I/O performance and drive longevity compared to entry‑level client SSDs. Typical use includes database acceleration, virtualization storage, and active tiered caches in enterprise compute nodes.

This drive is not intended for NVMe‑based storage stacks or PCIe‑NVMe slot configurations; it is built for SATA storage backplanes. It should not be used as the primary storage in systems without compatible SATA controllers or in non‑server consumer devices lacking backplane support.
