P40500-B21 - HPE 3.84TB SATA 6G RI SFF BC MV SSD

HPE P40500-B21 — 480GB SATA 6G Mixed Use SFF BC Multi-Vendor SSD

What it is

P40500-B21 is an HPE enterprise SATA SSD for ProLiant/Synergy servers.
It’s a 480GB 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 supply an equivalent approved SSD model over time, but performance and endurance stay within the published spec.

Why buyers pick P40500-B21 (plain English)

• Balanced read/write endurance
  Mixed Use is the right tier when you’re doing more than boot-only, but aren’t hammering the drive with heavy writes.

• Cost-effective enterprise SATA
  A dependable, budget-friendly SSD for VM tiers and general server storage where SATA is “fast enough.”

• Drop-in hot-swap simplicity
  Comes pre-mounted in the HPE carrier, so it slides straight into SFF ProLiant bays.

• Stable SKU for long-term builds
  Multi-Vendor sourcing helps keep supply consistent even when NAND models rotate.

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

TL;DR

P40500-B21 is HPE’s 480GB 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.
