P40507-B21 - HPE 1.92TB SAS 12G RI SFF BC Value SAS MV SSD

HPE P40507-B21 — 1.92TB SAS 12G Read Intensive SFF BC Value SAS Multi-Vendor SSD

What it is

P40507-B21 is an HPE enterprise server SSD.
It’s a 1.92TB SAS 12Gb/s, Read Intensive (RI), 2.5" SFF drive that ships on an HPE Basic Carrier (BC) for hot-swap ProLiant and Synergy bays. “Value SAS” means cost-optimized enterprise SAS, and “Multi-Vendor” means HPE may source equivalent drives from approved manufacturers while keeping the same published spec.

Why buyers pick P40507-B21 (plain English)

• Read-heavy performance with SAS reliability
  Faster and more robust than SATA for production reads, without NVMe cost.

• High capacity per SFF bay
  1.92TB is a strong density sweet spot for SFF servers.

• Dual-port SAS path
  Plays nicely in HA storage/server designs where you want redundant links.

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

Capacity

• 1.92 TB

Interface

• SAS 12 Gb/s (dual-port capable)

Form factor / carrier

• 2.5" SFF

Use case

• Read-heavy VM datastores, boot mirrors, app tiers, caching layers, general enterprise SSD pools where SAS is preferred over SATA.

Where it fits (and when to choose something else)

Perfect for:

• ProLiant/Synergy servers with SFF hot-swap bays

• Read-dominant virtualization and application workloads

• Replacing SAS HDD tiers with higher-speed SSD capacity

Choose something else if:

• You’re write-heavy → go Mixed-Use (MU) or Write-Intensive (WI) SSDs

• You want lowest latency / highest throughput → step up to NVMe Gen4/Gen5 SSDs

• You’re cost-optimizing pure boot/read → SATA RI SSDs may be cheaper

TL;DR

P40507-B21 is HPE’s 1.92TB SAS 12G Read-Intensive SFF SSD on Basic Carrier: a hot-swap, enterprise-qualified SAS SSD built for large, read-heavy server storage tiers.
