P40503-B21 - HPE 960GB SATA 6G MU SFF BC MV SSD

HPE P40503-B21 — 960GB SATA 6G Mixed Use SFF BC Multi-Vendor SSD

What it is

P40503-B21 is an HPE enterprise SATA SSD for ProLiant/Synergy servers.
It’s a 960GB SATA 6Gb/s, Mixed Use (MU), 2.5" SFF drive that ships on an HPE Basic Carrier (BC) for hot-swap bays. “Multi-Vendor” means HPE may fulfill with different approved SSD manufacturers over time, but performance/endurance stay within the published spec.

Why buyers pick P40503-B21 (plain English)

• Balanced read/write endurance for real workloads
  Mixed Use is the sweet spot when you’re doing more than boot-only, but don’t want to pay for write-intensive tiers.

• Cost-effective SATA capacity
  Great value for VM datastores, app servers, and general enterprise storage where SATA is enough.

• Drop-in hot-swap simplicity
  Comes pre-mounted in the HPE carrier, ready for SFF bays.

• Stable long-term SKU availability
  Multi-Vendor sourcing keeps supply consistent even as NAND models change.

60-second spec box (P40503-B21)

Capacity

• 960 GB

Interface

• SATA 6 Gb/s

Form factor / carrier

• 2.5" SFF

• HPE Basic Carrier (hot-swap)

Workload class

• Mixed Use (MU)

• Endurance class: ~3.4 DWPD range (balanced read/write)

Firmware / platform

• HPE-qualified, digitally signed firmware for ProLiant/Synergy

Warranty

• 3-year HPE warranty

Use case

• VM datastores, database/app tiers with moderate writes, general enterprise SSD storage, faster/safer alternative to HDDs or RI SATA when writes matter.

Where it fits (and when to choose something else)

Perfect for:

• ProLiant/Synergy servers with SFF hot-swap bays

• Virtualization clusters and mixed enterprise workloads

• Replacing older SATA SSDs where write activity isn’t trivial

Choose something else if:

• You’re mostly boot/read-heavy → a Read Intensive (RI) SATA SSD is cheaper

• You’re write-heavy (logs, heavy DB writes) → go Write Intensive (WI)

• You want higher throughput/latency → step up to SAS 12G or NVMe SSDs

TL;DR

P40503-B21 is HPE’s 960GB SATA 6G Mixed-Use SFF SSD on Basic Carrier: a hot-swap, enterprise-qualified SATA drive with balanced endurance for virtualization and general server workloads.
