HPE 960GB SATA MU SFF BC MV SSD - P40503-B21

HPE P40503-B21 960GB SATA SSD

Overview

The HPE P40503-B21 is a 960GB SATA 6G solid-state drive engineered for continuous-duty surveillance, archival, and enterprise storage environments where reliability and endurance matter more than raw speed. At 7mm height and 0.5 kg weight, it fits standard 2.5-inch hot-pluggable slots in HPE servers, storage arrays, and third-party systems without custom adapters. The 3.4 DWPD (drive writes per day) endurance rating translates to roughly 3.4 full-capacity rewrites per calendar day for a 5-year warranty window — a real metric for 24/7 recording systems or high-churn transactional workloads.

Key Features

• 960GB capacity with SATA 6G interface: Enough storage for moderate-scale surveillance (roughly 8–12 camera-days at 4MP 30fps H.265), and SATA ensures compatibility with any enterprise NVR or server with a 2.5-inch slot. No proprietary connectors or custom backplanes required.
• 3.4 DWPD endurance: Rated for sustained write cycles common in 24/7 recording or analytics processing. This is not consumer-grade TLC; the endurance spec means the drive is built to handle continuous ingest without premature wear-out. Compare this to consumer SSDs rated 0.3–1 DWPD, which would fail in months under surveillance duty.
• 61,000 random read IOPS; up to 72,000 @ Q32: Sufficient for parallel multi-stream playback and archive retrieval without I/O stalls. When a VMS operator scrubs through 48 hours of footage on 6 cameras simultaneously, this IOPS headroom keeps response time sub-100ms. The Q32 spec indicates the drive can sustain deep command queues typical of virtualized storage environments.
• 31,000 random write IOPS: Handles concurrent write streams from multiple cameras or analytics engines. In surveillance systems where H.265 compression reduces stream size, 31k IOPS is more than enough for dozens of simultaneous recording feeds on a single drive.
• 3.93 watts maximum power consumption: Low thermal footprint means no additional cooling requirements in enclosed storage enclosures. For comparison, 10W+ SSDs in dense arrays force costly airflow engineering; this one runs passive in standard HPE drive bays.
• Hot-pluggable design with 3/0/0 warranty: Field-replaceable without system shutdown. The 3-year manufacturer warranty is standard enterprise terms; the 0/0 notation indicates no additional proactive or accidental damage coverage (standard for this tier). In surveillance deployments, this means you can swap a failing drive during business hours without powering down the NVR.

Integration & Compatibility

The P40503-B21 (often searched as P40503 B21) is HPE OEM form-factor certified and fits without modification into HPE ProLiant Gen10/Gen11 servers, StoreEasy appliances, and any system with a 2.5-inch SATA hot-swap bay. SATA 6G backward-compatibility means it works in legacy 3G bays, though at reduced speed. Third-party NVRs and storage arrays using standard SATA slots (Synology, QNAP, Hikvision, Dahua industrial NVRs) recognize it as a standard SATA device — no driver installation needed. If you're building a hybrid surveillance array mixing archival SSDs and mechanical drives, this drive's consistent 3.93W power draw simplifies power-budget calculations.

What's in the Box

The P40503-B21 ships as a bare drive. No mounting brackets, cables, or documentation are included in the standard package — this is typical for enterprise OEM SSDs. You'll need a compatible 2.5-inch hot-swap caddy or bay adapter if your storage system uses a different form factor.

Frequently Asked Questions

Q: What does 3.4 DWPD mean for a surveillance recorder?

A: DWPD (Drive Writes Per Day) tells you how many times the entire drive capacity can be written per day before the drive is considered worn out. At 3.4 DWPD over 5 years, the P40503-B21 can absorb approximately 6,204 TB of cumulative writes (960GB × 3.4 × 365 × 5). For a 24/7 surveillance system recording 8 cameras at 4MP, that's roughly 18–24 months of continuous operation before reaching rated endurance limits. Consumer SSDs (0.3–1 DWPD) fail much sooner under this duty cycle.

Q: Is the P40503-B21 compatible with non-HPE NVRs?

A: Yes. SATA 6G is a standard interface. Any NVR with a 2.5-inch SATA hot-swap bay (Synology, QNAP, Hikvision, Dahua, Milestone-based appliances) recognizes it as a standard drive. No firmware or driver is required. Install it in the bay, power on the NVR, and the system detects it as a new SATA device.

Q: What's the warranty on the P40503-B21?

A: Manufacturer warranty is 3 years from purchase. The 3/0/0 code means 3-year limited hardware warranty; no extended coverage for accidental damage or proactive replacement. Standard enterprise OEM terms.

Q: Will this drive fit my existing storage enclosure?

A: The P40503-B21 is 7mm thick and uses a standard 2.5-inch SATA connector. If your enclosure has a 2.5-inch SATA hot-swap bay or caddy, yes. If it uses 3.5-inch bays or proprietary connectors, you'll need a form-factor adapter. Check your enclosure's specification sheet for supported drive form factors.

Q: Can I use the P40503-B21 in a surveillance server with multiple camera feeds?

A: Yes. The 61,000 random read IOPS and 31,000 write IOPS handle parallel multi-stream workloads. For example, a surveillance server recording 12 cameras simultaneously and serving 3 live-playback sessions draws roughly 8,000–12,000 IOPS sustained. This drive has sufficient headroom. The 3.93W power draw also keeps thermal load low in dense server enclosures.

Q: Is the P40503-B21 NDAA-compliant?

A: NDAA Section 889 compliance is not listed in the product specification. If NDAA compliance is a hard requirement, contact HPE directly with the SKU (P40503-B21) to confirm eligibility or consider sourcing from a NDAA-verified supplier.

I spec the P40503-B21 into surveillance appliances and archival arrays where endurance and form-factor discipline matter. The 3.4 DWPD rating is the critical differentiator here — it tells you this drive was designed for datacenter-class 24/7 duty, not consumer refresh cycles. If you're replacing a failed drive in a surveillance system that's been recording continuously for 3+ years, this is the SKU that won't surprise you with another failure in six months.

Technical Highlights:

• 3.4 DWPD over 5 years: Translates to roughly 6,200 TB of rated write endurance. In a surveillance archival scenario (500–800 GB/day per camera tier), that's 18–24 months of continuous ingest before hitting the rated wear limit. Consumer TLC (0.3–1 DWPD) gives you 2–4 months under the same load.
• 61,000 sustained random read IOPS; 72,000 @ Q32: Handles multi-stream playback and archive retrieval without I/O queuing. When a VMS needs to scrub six concurrent camera feeds for evidence extraction, the Q32 spec shows the drive can handle deep queues without stalling. Most archive SSDs throttle under this load.
• 3.93 watts maximum: Passive cooling in HPE bays; no additional airflow or thermal design required in dense storage enclosures. Reduces OPEX on cooling and allows tighter packing of archive tiers.

Deployment Considerations:

• SATA 6G is the interface bottleneck, not the drive. If you're recording 12+ cameras at 4K 30fps H.265, a single SATA drive maxes out around 400 MB/s throughput before I/O wait becomes visible. Plan for multiple drives or NVMe alternatives if you're approaching saturation.
• Hot-pluggable design is a win for 24/7 surveillance; a failing drive can be swapped without shutting down recording. However, 3-year warranty is standard enterprise terms — no accidental damage or extended proactive coverage. Budget for a hot spare if this is a mission-critical archive tier.

Deploy the P40503-B21 into NVR archival tiers, surveillance storage arrays, or Milestone/Genetec appliance expansion where you need 960GB in a compact hot-swap slot and can't afford consumer-grade DWPD ratings. It's the right choice for multi-year continuous recording systems where drive replacement is a service call, not a field emergency.
