HPE P40502-B21 480 GB 2.5" SATA internal SSD

Server SSD for mixed workloads

The HPE P40502-B21 is a 2.5 inch internal solid state drive built for server and workstation platforms. It delivers 480 GB of capacity over a SATA 6 Gbps interface and carries a 3.5 DWPD endurance rating for mixed use applications. Hot-plug support allows insertion or removal without powering down the host system. End-to-end data protection and advanced wear leveling help maintain data integrity across the drive life.

Verify SATA bay and hot-plug capability

Confirm the target chassis provides a 2.5 inch drive bay with a SATA backplane that supports hot-plug operation. The drive draws 3.56 watts and measures 14.6 mm in height so the bay must accommodate that thickness. Ensure the server firmware and drive carrier are compatible with the P40502-B21 part number before installation. No additional cabling is required beyond the standard SATA power and data connections.

Sustained write behaviour at rated endurance

Under continuous mixed workloads the drive is rated for 3.5 drive writes per day across its warranty period. Advanced wear leveling distributes writes evenly across the NAND to prevent premature block exhaustion. Thermal throttling may engage if the drive temperature exceeds safe limits during prolonged heavy I/O. Performance remains consistent within the SATA 600 Mbps interface ceiling as long as the workload stays within the specified endurance envelope.
