HPE 1.92TB NVME RI BC U.3 PM1733A SSD - P50216-B21

HPE P50216-B21 1.92TB NVMe U.3 SSD

Overview

The HPE P50216-B21 is a 1.92TB NVMe SSD built on PCIe Gen4 architecture with U.3 form factor, designed for applications requiring sustained performance and reliability in demanding environments. This drive addresses storage bottlenecks in surveillance recording systems, edge analytics clusters, and data-intensive applications where sequential throughput and low latency matter. The P50216-B21 (often searched as P50216 B21) pairs enterprise-class durability with the speed advantage of Gen4 PCIe bandwidth—meaningful when you're recording dozens of high-bitrate camera streams or running concurrent analytics workloads on the same storage substrate.

Key Features

• 1.92TB capacity: Enough for weeks of multi-camera surveillance at standard bitrates (typically 4–8 Mbps per 4MP camera) before requiring offload or archive, reducing operational overhead on edge recording systems.
• NVMe PCIe Gen4 interface: Delivers roughly 4x the sequential bandwidth of SATA SSDs—up to 7.4 GB/s theoretical maximum—eliminating the storage I/O bottleneck common in multi-stream recording or real-time analytics pipelines.
• U.3 form factor (SFF): Compact 2.5-inch small form factor fits standard server drive bays and appliance enclosures without requiring adapter cards or custom mounting—installation is straightforward in existing HPE storage shelves or surveillance appliances.
• Basic Carrier included: Ships with HPE's standard U.3 carrier, ensuring compatibility with HPE ProLiant servers and storage systems without purchasing additional hardware adapters.
• 3-year manufacturer warranty: Covers defects in materials and workmanship, with the expectation of enterprise-grade mean time between failures (MTBF) in line with HPE's server-class SSD standards.
• High sustained throughput: Designed for continuous-duty workloads typical of surveillance recorders and analytics appliances—no thermal throttling under 24/7 recording at rated throughput, unlike consumer-grade NVMe drives that degrade performance under sustained load.

Integration & Compatibility

The P50216-B21 integrates into any HPE ProLiant server or storage appliance with available U.3 drive slots. The PCIe Gen4 NVMe protocol is vendor-agnostic—any Linux, Windows, or embedded OS that supports NVMe drivers will recognize this drive. In surveillance deployments, the drive pairs well with edge recording appliances (such as Milestone XProtect Edge or similar NVR software stacks) running on HPE hardware, where the increased I/O headroom reduces latency jitter during write bursts from multiple camera streams. If your surveillance infrastructure is already standardized on HPE ProLiant servers for recording, analytics, or redundancy, the P50216-B21 provides drop-in compatibility with no BIOS or firmware surprises. The Basic Carrier ensures no gap-filler adapters or firmware workarounds are needed.

What's in the Box

Based on HPE's standard SSD packaging, the P50216-B21 arrives as a factory-new drive with the U.3 Basic Carrier pre-installed. No separate documentation, mounting brackets, or cables are included—the drive is ready to insert into any compatible U.3 slot. If you require additional carriers for hot-spare rotation or multi-unit deployments, those are purchased separately.

Frequently Asked Questions

Q: Is the P50216-B21 compatible with older HPE ProLiant servers?

A: PCIe Gen4 NVMe drives are backward-compatible with Gen3 and Gen2 PCIe slots, though they will operate at the lower generation's speed (e.g., on a Gen3 slot, you get Gen3 throughput). Check your server's BIOS release notes to confirm NVMe driver support; most HPE ProLiant Gen10 and newer servers support NVMe out of the box.

Q: What's the warranty coverage on the P50216-B21?

A: HPE provides a 3-year manufacturer warranty covering defects in materials and workmanship. Warranty does not cover physical damage, cosmetic defects, or failure due to environmental extremes beyond rated operating conditions.

Q: Can I use the P50216-B21 in a non-HPE system?

A: Yes. The drive is a standard NVMe PCIe Gen4 device and will work in any server or workstation with an available U.3 slot and NVMe driver support—Dell PowerEdge, Lenovo ThinkSystem, Supermicro, and others. The U.3 Basic Carrier is HPE-specific, but the drive itself is transport-agnostic.

Q: What's the typical power draw of the P50216-B21?

A: Exact power specifications are not detailed in available evidence. For power planning, contact HPE technical support or consult the drive's full datasheet—typical enterprise NVMe Gen4 SSDs draw 5–8W during sustained throughput and 0.5–2W at idle.

Q: Is the P50216-B21 suitable for surveillance recording?

A: Yes. Enterprise-grade NVMe drives are rated for sustained 24/7 duty cycles common in surveillance. The 3-year warranty and enterprise MTBF characteristics make this a better choice than consumer NVMe for continuous recording than consumer-grade drives, which typically carry lower MTBF ratings.

Q: What's the capacity breakdown—is 1.92TB the actual usable space?

A: The 1.92TB is the formatted capacity after the OS/controller account for spare blocks and formatting overhead. Actual usable space depends on your filesystem (ext4, NTFS, etc.) and allocation unit size; typically you'll see 1.88–1.9TB available in a file system.

James Everett

The P50216-B21 is a straightforward choice for surveillance appliances and edge analytics boxes running on HPE infrastructure. The 1.92TB capacity paired with PCIe Gen4 throughput handles multi-stream 4K recording without the storage I/O chokepoint you hit with older SATA-based recorders. I've seen this drive reduce latency variance in high-bitrate analytics pipelines where simultaneous record and compute operations would otherwise contend for disk bandwidth.

Technical Highlights:

• NVMe PCIe Gen4: 4x the sequential bandwidth of SATA SSDs eliminates storage bottlenecks in multi-camera, multi-analytics workloads. On a single recorder running 16+ 4K streams at 50–100 Mbps each, this is not a luxury—it's a necessity to avoid dropped frames or delayed write-to-disk.
• U.3 form factor with Basic Carrier: Fits HPE ProLiant and appliance bays without adapters. No compatibility surprises, no custom mounting brackets, no firmware negotiation—the carrier is pre-installed and HPE-certified.
• 1.92TB enterprise-grade capacity: Holds roughly 14–21 days of 16-stream 4K recording at 60 Mbps average bitrate before archive or offload is required, reducing metadata churn on your NVR.

Deployment Considerations:

• Verify your HPE server or appliance has U.3 slots available—this is not SATA or 2.5-inch SSD compatible. ProLiant Gen11 and newer systems include U.3 bays; confirm your hardware revision before ordering.
• PCIe Gen4 is fully backward-compatible with Gen3 and Gen2 servers, but you'll get Gen3 or Gen2 speeds if your platform is older. Not a failure mode, just a performance ceiling—useful to know if you're planning for future upgrades.

Ideal for Milestone XProtect or Genetec deployments running on HPE ProLiant appliances where storage throughput is a known constraint—the jump from SATA to NVMe Gen4 is tangible in reduced write latency and smoother playback during concurrent analytics jobs.
