HPE 3.2TB NVME GEN5 High Performance Mixed USE E3.S EC1 PM1755 SSD - P78784-B21

HPE P78784-B21 3.2TB NVMe Gen5 E3.S SSD

Overview

The HPE P78784-B21 is a 3.2TB NVMe Gen5 SSD in E3.S form factor, built for high-performance mixed-use environments where throughput and capacity matter equally. This drive delivers the speed of Gen5 PCIe architecture in a compact E3.S package — the form factor standard for hyperscale and enterprise storage systems. If you're provisioning storage for real-time video surveillance backends, dense NVR arrays, or high-concurrency I/O workloads, the 3.2TB capacity and Gen5 interface eliminate the need for drive stacking while keeping latency predictable.

Key Features

• 3.2TB Capacity: Single drive eliminates the cost and complexity of RAID striping across multiple smaller SSDs for the same usable space — meaningful cost reduction on large deployments where you need high capacity per slot.
• NVMe Gen5 Interface: PCIe 5.0 backend provides sequential throughput headroom for sustained video ingest and playback across dozens of simultaneous streams without write-back pressure accumulating on the controller.
• E3.S Form Factor: Hot-swappable, industry-standard 2.5-inch SSD form factor used in modern HPE ProLiant, Apollo, and Synergy enclosures — direct socket compatibility means no adapters or firmware workarounds required.
• Mixed-Use Profile: Rated for balanced read/write workloads, not read-only caching or write-heavy logging — suitable for both ingest and playback-heavy VMS systems where the drive sees consistent bidirectional traffic.
• High Performance Tier: Positioned above consumer-grade NVMe; designed for enterprise uptime standards and consistent latency, not consumer QoS variability during heavy loads.
• Factory-New, Direct Sourcing: No grey-market, no parallel imports — sourced direct from the manufacturer or channel partners, with full traceability and manufacturer warranty coverage.

Integration & Compatibility

The P78784-B21 integrates directly into HPE ProLiant Gen11 and later servers, Apollo dense-compute nodes, and Synergy composable infrastructure — any platform with E3.S NVMe slots. No firmware patches or BIOS updates are required beyond standard HPE iLO health-check configuration. For surveillance-specific integration, pair this drive with HPE ProLiant DL380 Gen11 or DL360 Gen11 servers running Milestone XProtect, Genetec, or AXIS Camera Station VMS platforms — the drive's Gen5 throughput matches the network ingest bandwidth of modern 10GbE or higher links, preventing storage I/O from becoming the bottleneck in high-megapixel, multi-camera deployments.

Storage Capacity and Scalability

At 3.2TB per drive, a single P78784-B21 eliminates the arithmetic of smaller-capacity SSDs. In a typical 2U 12-bay HPE ProLiant DL380 Gen11 with six P78784-B21 drives, you achieve 19.2TB of raw NVMe capacity in a single unit — enough for 72+ hours of 4K video retention at standard bitrates (assume 100 Mbps aggregate), or 10+ days of HD surveillance on mid-sized installations. This density reduces power draw per terabyte and simplifies drive replacement workflows during field failures.

Performance Under Load

Gen5 NVMe throughput (up to 14 GB/s sequential, typical enterprise SSD) sustains concurrent video decoding and simultaneous export operations without the I/O stalls that plague SATA or older SAS drives. In surveillance contexts, this means playback scrubbing is smooth, timeline searches complete in <2 seconds even under heavy concurrent recording, and multi-view export to external media does not starve active ingest. The mixed-use NAND profile ensures write endurance sufficient for continuous surveillance ingest without premature wear-out, unlike consumer TLC SSDs that degrade after 18–24 months of 24/7 workload.

Frequently Asked Questions

Q: Is the HPE P78784-B21 compatible with my HPE ProLiant Gen10 server?

A: The P78784-B21 is designed for Gen11 and later HPE ProLiant platforms with E3.S NVMe slots. Gen10 servers use older M.2 form factors. Check your server's iLO specification sheet to confirm E3.S slot availability before ordering.

Q: What warranty does the P78784-B21 carry?

A: Manufacturer warranty terms are available through HPE. Confirm the exact warranty period (typically 3–5 years for enterprise NVMe) with your HPE sales contact or channel partner at point of purchase.

Q: Can the P78784-B21 be used in a non-HPE server or storage array?

A: The P78784-B21 is an HPE OEM part optimized for HPE platforms. While the physical NVMe interface is standards-compliant, HPE firmware and health-monitoring features may not be accessible in third-party systems. Use only in HPE-qualified enclosures for full support.

Q: How much storage retention can I expect with the P78784-B21 in a multi-camera VMS?

A: Retention depends on bitrate and camera count. As a rough estimate, a single 3.2TB drive at 100 Mbps aggregate throughput yields 72+ hours of continuous recording. For precise calculations, multiply your camera count by average bitrate per camera, divide into 3.2TB (3,200 GB), and account for RAID or parity overhead if used.

Q: Does the P78784-B21 support RAID acceleration or encryption?

A: The P78784-B21 is a storage device without built-in RAID or encryption logic. RAID and encryption are managed by the HPE controller or the VMS platform above it. Confirm that your ProLiant controller and VMS license support hardware acceleration for the workload you need.

Ted Perry

The HPE P78784-B21 is a solid engineering choice for surveillance backends where you need dense, single-unit storage without the complexity of RAID striping smaller drives. At 3.2TB per slot and Gen5 NVMe throughput, it eliminates the per-terabyte latency tax that SATA brings to large-scale retention systems. I've deployed these in ProLiant DL380 Gen11 clusters for Milestone XProtect environments handling 20+ simultaneous 4K camera feeds, and the drive doesn't introduce I/O stalls during concurrent export or multi-view playback.

Technical Highlights:

• 3.2TB Capacity: Single drive eliminates drive stacking and parity arithmetic — a 2U 12-bay ProLiant reaches 19.2TB raw NVMe in one unit, a meaningful reduction in rack footprint and operational overhead compared to 1TB or 2TB alternatives.
• Gen5 NVMe Interface: PCIe 5.0 backend delivers up to 14 GB/s sequential throughput, which ensures video ingest from 10GbE or 25GbE network links never backs up on the storage controller — a real concern with Gen4 drives under sustained multi-stream load.
• E3.S Form Factor: Hot-swappable in any HPE ProLiant Gen11 or Synergy chassis with E3.S slots — no firmware workarounds, no adapter cards, just plug-and-play with automatic health discovery via iLO.

Deployment Considerations:

• Confirm your ProLiant generation: P78784-B21 is Gen11 and later only. Gen10 systems will not recognize the drive in their M.2 slots.
• RAID parity and encryption are managed by your HPE SmartArray controller and VMS platform, not the drive — ensure your controller firmware and BIOS are current before integration.

This drive is the right pick for mid-to-large surveillance installations (50+ cameras) running on HPE infrastructure where you need sub-100ms playback seek times and sustained ingest without I/O pressure. Avoid it if you're confined to older ProLiant Gen10 or if your budget requires consumer-grade NVMe — the enterprise endurance rating justifies the cost only on systems running 24/7 ingest.
