HPE 480GB SATA RI SFF BC MV SSD - P40497-B21

HPE P40497-B21 480GB SATA SSD

Overview

The HPE P40497-B21 is a 480GB SATA 6G solid-state drive engineered for sustained surveillance recording and moderate-throughput enterprise storage environments. This drive delivers 63,000 random read IOPS under typical queue depths, with a peak of 65,500 IOPS at Q32—meaningful for workloads that demand consistent I/O performance without premium pricing. The 7mm form factor slots into standard 2.5-inch SFF (small form factor) bays, and the hot-pluggable design means you can swap failed drives without downtime on systems that support hot-swap architecture.

Built on SATA interface (6 Gbps), the P40497-B21 trades raw speed for reliability and cost predictability. At 0.5 DWPD (drive writes per day) endurance, this is a surveillance-grade SSD—designed to absorb moderate write traffic typical of video storage, not extreme database workloads. Power consumption sits at 3.36 watts, a critical factor in power-constrained enclosures or rack environments where thermal headroom is tight.

Key Features

• 480GB capacity: Enough for 2–5 days of 24/7 recording across 4–8 mid-resolution cameras (depending on codec and bitrate), or medium-term cold-storage archival. Pair multiple drives in a RAID array for redundancy.
• 63,000 random read IOPS; peak 65,500 at Q32: Fast enough to handle playback scrubbing and simultaneous multi-stream retrieval without noticeable stalls. Exceeds minimum IOPS for real-time read-heavy surveillance queries.
• 15,000 random write IOPS; peak 15,400 at Q1: Designed to sustain continuous ingest from multiple cameras without write queuing or latency spikes. Lower than read IOPS is normal for surveillance drives—you write once, read many.
• 0.5 DWPD endurance rating: Conservative specification reflects surveillance-workload assumptions (moderate daily writes). In a typical 24/7 camera-ingest scenario, this drive is warrantied for multi-year service before wear reaches end-of-life thresholds. Not suitable for transaction-heavy databases or extreme IoT sensor logging.
• 7mm form factor, hot-pluggable design: Fits standard 2.5-inch SFF drive bays in enterprise storage appliances, surveillance NVRs, and edge recorders. Hot-swap capability reduces downtime—pull the drive, insert a replacement, and resume recording without system reboot (assuming the host controller supports hot-swap).
• 3.36W power envelope: Low thermal footprint critical in fanless or sealed surveillance enclosures. Reduces cooling load and extends battery backup time on UPS-backed systems. In multi-drive arrays, this efficiency multiplies across the storage pool.

Integration and Compatibility

The P40497-B21 integrates into any system with a 2.5-inch SATA 6G bay. Enterprise NVRs, surveillance storage appliances, and ruggedized edge recorders commonly accept this form factor. Confirm your system's BIOS or firmware supports hot-swap and recognizes the drive's capacity without firmware limitations. Some legacy RAID controllers cap capacity per drive—verify compatibility with your storage controller's datasheet before deployment in critical arrays.

SATA 6G is a mature standard with broad ecosystem support. If your system mandates NVMe or requires faster sequential throughput, step up to a higher-tier SSD; however, SATA remains the cost-effective choice for surveillance retention and archival where sustained I/O and raw speed matter less than capacity per dollar and reliability.

Frequently Asked Questions

Q: Is the P40497-B21 suitable for 24/7 continuous recording?

A: Yes. The 0.5 DWPD endurance rating and 15,000 random write IOPS are calibrated for persistent video ingest. In a typical four-camera recording scenario (H.264, 6 Mbps per stream), you'll write approximately 2.6 GB per hour per camera—well within the drive's write budget. Multi-drive redundancy (RAID 5 or 6) adds fault tolerance.

Q: What happens if I exceed 0.5 DWPD?

A: Exceeding DWPD voids warranty and accelerates wear. In surveillance use, you rarely hit this ceiling unless you're streaming raw uncompressed video or running parallel ingest + transcoding jobs. Monitor write rates via your storage system's SMART counters.

Q: Can I use the P40497-B21 in a hot-swap rack without a reboot?

A: Yes, if your storage controller and motherboard support SATA hot-swap. Most enterprise systems do. Verify your controller's documentation; some require a software-level disconnect command before physical removal. Always stop active I/O to that drive first.

Q: How does 63,000 IOPS compare to NVMe?

A: NVMe drives exceed 100,000 IOPS routinely, but surveillance workloads rarely need that speed. SATA's 63k IOPS handles simultaneous playback of 8–12 video streams plus ingest without bottleneck. NVMe adds cost for negligible surveillance benefit.

Q: Is the P40497-B21 NDAA Section 889 compliant?

A: Compliance certification is not documented in available evidence. If NDAA compliance is a procurement requirement, contact your procurement team or HPE directly for attestation.

Q: What warranty does the P40497-B21 carry?

A: Specific warranty duration is not documented in available evidence. HPE SSDs typically carry manufacturer warranty commensurate with endurance rating. Verify the warranty period with your distributor or HPE product documentation.

The P40497-B21 sits in a sweet spot for surveillance storage: enough raw I/O (63,000 random read IOPS) to keep playback responsive without the premium price of NVMe, and a 0.5 DWPD endurance curve that aligns with typical camera ingest patterns. If you're building or refreshing a mid-scale NVR array or edge storage system, this 480GB SATA drive deserves a serious look.

Technical Highlights:

• 63,000 random read IOPS (65,500 peak at Q32): Supports 8–12 concurrent video playback streams without I/O stalls. Real-world surveillance playback rarely exceeds this threshold, so you're not paying for unused performance headroom.
• 15,000 random write IOPS: Absorbs continuous ingest from 4–6 simultaneous camera feeds (H.264/H.265) without write queuing. The lower write IOPS versus read is intentional—surveillance is fundamentally write-once, read-many.
• 3.36W power draw: In a 16-drive storage array, that's roughly 54W total—manageable in fanless or sealed enclosures. Extends UPS backup window by 15–20% compared to 5W drives, a real factor on battery-backed systems.
• 7mm form factor with hot-swap support: Drop into 2.5-inch bays without racking gymnastics. Hot-pluggable design means drive failure doesn't force a maintenance window—swap and resume, assuming your RAID group has redundancy.

Deployment Considerations:

• The 0.5 DWPD endurance spec assumes moderate write traffic—surveillance ingest, not transaction databases. If your workload includes heavy parallel read + write (e.g., real-time analytics + archive simultaneously), monitor SMART wear counters monthly. Exceeding DWPD voids warranty and accelerates cell degradation.
• SATA 6G maxes out at 550 MB/s theoretical throughput. In surveillance, you'll never hit that ceiling, but if you need sub-10ms latency on large sequential reads, NVMe is the only path—and the cost jump is significant. For video playback and cold archival, SATA is efficient.
• Confirm your storage controller or NVR firmware recognizes the full 480GB without capacity limits. Legacy RAID firmware sometimes caps per-drive size; a quick controller BIOS check prevents nasty surprises.

Deploy the P40497-B21 in mid-scale edge recording systems, NVR arrays, and warm-archival appliances where you need 2–5 days of multi-camera retention without breaking budget or thermal constraints. Pair in RAID 5 or 6 for fault tolerance, and you've got a reliable, cost-effective surveillance storage backbone.
