HPE 1.92TB SATA RI SFF BC MV SSD - P40499-B21

HPE P40499-B21 1.92TB SATA SSD for Surveillance Storage

Overview

The HPE P40499-B21 is a 1.92TB SATA SSD built for continuous surveillance and video archival workloads where sustained write performance and reliability matter more than raw speed. This is a hot-pluggable drive designed to slide into NVR storage arrays without powering down the system — a critical convenience for 24/7 monitoring environments where downtime is not an option. The compact 7mm height (21.92 x 22.86 x 14.61 cm, 0.5 kg) fits standard 2.5-inch server and appliance bays.

Key Features

• 1.92TB capacity with 0.8 DWPD endurance: Rated for 0.8 drive writes per day over the warranty period — meaning if your NVR writes roughly 1–2TB daily across all cameras, this drive will handle multi-year operation without wearing out. 0.8 DWPD is conservative by design, prioritizing surveillance longevity over maximum density.
• 56,000 IOPS random read performance (@ Q32): Handles spike loads from multiple simultaneous playback requests or analytics queries across a surveillance database. When you pull 4–5 concurrent video clips from archive, the drive won't bottleneck the query.
• 25,000 IOPS random write performance (@ Q32): Sustained write throughput for continuous ingest from 12–24 camera streams. This is where surveillance SSDs prove their value — writes don't degrade as the drive fills, unlike consumer spinning disks.
• SATA 6G interface: Standard enterprise SATA 6Gbps connection — every NVR and server supports it natively. No proprietary controllers, no compatibility questions. Works with Milestone, Genetec, Uniview, Hikvision appliances, or any NVR platform that accepts enterprise SATA drives.
• 3.53W typical power draw: Low power consumption keeps thermal load manageable in rack-mounted or fanless NVR enclosures. At 3.53W sustained, you're not adding significant heat or drawing excess current from your NVR's internal PSU — relevant for multi-drive configurations where every watt counts.
• Hot-pluggable design: Remove and replace without shutting down the NVR. Surveillance systems running 24/7 cannot afford planned maintenance windows. This drive supports on-the-fly replacement in RAID arrays and hot spares.

Integration & Compatibility

The P40499-B21 integrates into any enterprise surveillance platform using standard SATA drive bays. HPE surveillance-grade SSDs are commonly used in mid-range NVRs from Hikvision, Dahua, Uniview, and generic server-based VMS appliances. Confirm your NVR or server documentation lists HPE SATA SSDs as approved replacements — most do, but some manufacturers lock drive models. The 7mm form factor fits all 2.5-inch SATA slots; verify bay depth if your NVR uses proprietary cages. If your system runs RAID 5 or RAID 6 across multiple drives, use matching capacity and endurance ratings to avoid rebuild bottlenecks.

Deployment Notes

Install the P40499-B21 during initial NVR setup or as a hot-swap replacement in existing arrays. If upgrading from spinning disks, expect 5–10× faster forensic playback and near-instant analytics searches. Pair multiple drives for storage depth — a 12-camera 30fps system writing continuously generates roughly 2–3TB daily depending on codec and resolution, so calculate retention in multiples of 1.92TB capacity. The drive operates across industrial temperature ranges suitable for server rooms and outdoor-rated NVR enclosures; confirm your environment stays within the system's rated specifications.

What's in the Box

The P40499-B21 ships as a bare drive — no mounting bracket, cable, or documentation included in the box. Order separately if you need 2.5-inch SATA cables or drive trays specific to your NVR enclosure.

Frequently Asked Questions

Q: Can I use the P40499-B21 in a NVR that previously used spinning disks?

A: Yes. The SATA 6G interface is backward compatible with all standard SATA connections. Swap the old drive for the P40499-B21 and reinitialize the volume in your NVR's storage settings. No firmware updates required.

Q: What does 0.8 DWPD mean for a surveillance camera system?

A: DWPD (drive writes per day) is an annualized durability rating. 0.8 DWPD means the drive can tolerate 0.8 full capacity writes daily for the warranty period. In a 12-camera continuous recording system writing 2TB daily, this drive will last 3–5 years before reaching rated wear limits, assuming linear write patterns.

Q: Does the P40499-B21 require special mounting hardware?

A: No. It uses standard 2.5-inch SATA mounting. If your NVR has fixed drive bays, the drive installs directly. If you use external trays or cages, ensure the tray supports 2.5-inch SATA drives — most do.

Q: Will the P40499-B21 reduce my NVR's power consumption compared to a 7200 RPM hard disk?

A: Yes. The drive pulls 3.53W typical; a comparable 7200 RPM HDD draws 6–8W. Over 12 months continuous operation, you'll save roughly 40–50W of system power, lowering both electricity costs and thermal load in the enclosure.

Q: Is the P40499-B21 suitable for high-frame-rate or 4K camera deployments?

A: For 4K multi-camera systems (4–8 cameras at 30fps), 1.92TB alone may require frequent archival cycles. Pair multiple P40499-B21 drives in RAID or configure tiered storage (SSD for hot data, external archive for cold storage). For high-frame-rate HD systems (24+ cameras at 60fps), calculate write throughput: most can sustain 150–250 MB/s per camera, meaning 4–6 cameras max on this single drive.

The P40499-B21 is purpose-built for surveillance workloads where the access pattern is write-heavy and predictable. Unlike consumer or enterprise general-purpose SSDs, this drive's 0.8 DWPD rating reflects the reality of NVR duty — you're not swapping random reads and writes; you're streaming camera feeds 24/7 and occasionally pulling clips for review. The combination of 56,000 IOPS random read and 25,000 IOPS random write at queue depth 32 tells you that concurrent playback requests won't cause stalls, even in multi-user VMS environments.

Technical Highlights:

• 0.8 DWPD endurance over the warranty period: Translates to 4–5 years of continuous ingest on a typical 12-camera system writing 2TB daily. Conservative rating means fewer warranty claims and predictable lifecycle planning — you can retire the drive on schedule rather than emergency replacement.
• 56,000 IOPS random read @ Q32: Handles parallel playback requests from multiple concurrent users or analytics engines. In a Milestone or Genetec deployment with 20–30 users accessing clips simultaneously, this IOPS ceiling prevents the storage subsystem from becoming the bottleneck.
• 3.53W typical power consumption: In a 16-drive NVR appliance, you're looking at ~56W total SSD power draw versus 96–128W for equivalent 7200 RPM spinning drives. That's a 40% reduction in thermal load — critical in fanless or thermally constrained enclosures where one hot component can trigger cascade failures.

Deployment Considerations:

• Verify your NVR firmware recognizes the P40499-B21 in its approved drive list before purchase. Some manufacturers ship with whitelist restrictions, though HPE enterprise SSDs rarely trigger compatibility issues. If your NVR uses proprietary RAID controllers, test with one drive before committing to a full array upgrade.
• Monitor remaining write endurance if you're storing the drive beyond 5 years or operating in extreme temperature environments (above 50°C). SSDs don't warn you when DWPD is exhausted — they simply stop accepting writes. Use your NVR's SMART monitoring and set threshold alerts at 80% of rated lifespan.

Size this SSD for systems running 8–16 continuous HD cameras (1–3 TB daily ingest). For larger installations, aggregate multiple P40499-B21 drives in RAID 5 or 6. The hot-pluggable design means you can upgrade or replace failed units without downtime — exactly what a 24/7 surveillance operation requires.
