P40505-B21 - HPE 3.84TB SATA 6G MU SFF BC MV SSD

HPE P40505-B21 — 3.84TB SATA 6G Mixed Use SFF BC Multi-Vendor SSD

What it is

P40505-B21 is an HPE enterprise SATA SSD for ProLiant servers.
It’s a 3.84TB 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 equivalent approved SSD models over time, while keeping the same endurance/workload class.

Why buyers pick P40505-B21 (plain English)

• High capacity + balanced endurance
  Mixed Use is the right tier when you need large flash capacity but still expect meaningful writes (VMs, apps, databases).

• Great density per SFF bay
  3.84TB is a strong “TB-per-slot” upgrade without paying for SAS/NVMe.

• Simple hot-swap deployment
  Pre-mounted in the HPE carrier, so it’s easy to install and service.

• Enterprise-qualified reliability
  HPE firmware validation and consistent supply via Multi-Vendor sourcing.
