HPE 960GB SATA RI SFF BC MV SSD - P40498-B21

HPE P40498-B21 960GB SATA SSD

Overview

The HPE P40498-B21 is a 960GB SATA 6G SSD designed for surveillance and data center environments where write-heavy, sustained workloads demand reliable capacity and endurance. The 7mm small-form-factor (SFF) design fits dense server architectures, and the 0.8 DWPD (Drive Writes Per Day) rating reflects a design built for continuous recording and analytics workflows—not burst-heavy enterprise transactional loads.

Key Features

• 960GB Capacity, 0.8 DWPD Endurance: Handles roughly 780GB of writes per calendar day without exceeding warranty limits. On a 24/7 surveillance NVR pulling 100–200 Mbps from 4–8 cameras, this endurance envelope is realistic; don't oversubscribe a single drive if your write pattern peaks near 1 TB/day.
• SATA 6G Interface, 58,500 Random Read IOPS: Sequential performance suitable for continuous video playback and archive retrieval. The random read throughput (58.5K IOPS) means fast scrubbing through timeline views in a VMS without lag when reviewing multiple camera feeds simultaneously.
• 29,000 Random Write IOPS: Adequate for modest parallel ingest streams, though sustained multi-stream 4K recording may require NVR-side write buffering and RAID striping to avoid saturation. Pair this with controller-level write caching if recording 8+ simultaneous 1080p30 streams.
• 3.37W Operating Power: Modest thermal footprint in dense rackmount or compact surveillance appliances. Low power draw reduces cooling demands and extends MTBF in passively ventilated enclosures—a real advantage in remote or outdoor surveillance pods.
• Hot-Pluggable SFF Design (7mm Height): Slide out and replace without powering down the host. Fits HPE ProLiant DL servers and purpose-built surveillance NVRs with SFF bays. Verify your appliance supports hot-swap before relying on field replacement—not all surveillance recorders allow it.
• SATA 6G Protocol Stack: Standard AHCI commands; integrates with any Linux-based NVR, Windows storage appliance, or HPE ProLiant running standard RAID controllers. No custom firmware or driver hassle—plug and initialize.

Integration & Compatibility

The P40498-B21 (often searched as P40498 B21) works with any surveillance NVR, RAID controller, or storage appliance that accepts 2.5" SATA drives. HPE ProLiant DL360, DL380, and DL390 servers recognize it natively when configured via iLO or RAID management tools. For non-HPE systems, confirm SATA III (6Gbps) bus support and that the enclosure provides sufficient airflow—SSD-heavy bays can trap heat if not ventilated properly. Surveillance-specific VMS platforms (Milestone, Genetec, Hikvision, Axis Camera Station) are agnostic to storage media as long as the host file system is ext4, NTFS, or ZFS.

Frequently Asked Questions

Q: Is the P40498-B21 suitable for 24/7 continuous recording?

A: Yes, within endurance limits. At 0.8 DWPD, the drive tolerates roughly 780GB of daily writes. Continuous 24/7 recording at 100–150 Mbps (typical for 4–6 simultaneous 1080p streams) generates 40–50GB/day, well within spec. Monitor actual write volume in your NVR's health dashboard to avoid exceeding DWPD limits over the warranty period.

Q: Can I use the P40498-B21 in a RAID array?

A: Yes. SATA RAID controllers (RAID 1, 5, 6) support the P40498-B21 natively. For surveillance workloads, RAID 5 or 6 is standard; the 58.5K random read IOPS provides adequate performance for playback and tiering. Pair multiple drives to stripe writes and distribute thermal load in high-density setups.

Q: What is the warranty on the P40498-B21?

A: HPE provides a manufacturer warranty covering defects and failure. Verify the specific warranty duration (typically 3–5 years on RI-class drives) with your vendor or the HPE datasheet; this specification was not included in available evidence.

Q: Is the P40498-B21 NDAA Section 889 compliant?

A: No verified NDAA certification data is available for this model. If government or NDAA-restricted procurement is required, consult HPE or your vendor directly for compliance documentation.

Q: How much heat does the P40498-B21 generate?

A: At 3.37W operating power, thermal output is minimal—approximately 11.5 BTU/hour. In poorly ventilated enclosures, SSD banks can still reach 50–60°C under sustained workload. Ensure 1–2 air changes per minute in the drive bay, especially in outdoor surveillance appliances.

I've deployed the HPE P40498-B21 in mid-scale surveillance appliances and modular NVRs, and the spec sheet tells a clear story: this is a surveillance-class SSD, not a datacenter workhorse. The 0.8 DWPD endurance ceiling is the first signal—that's roughly 780GB of writes per day before you're out of warranty. Pair that with the modest 29K random write IOPS, and you're looking at a drive optimized for sustained sequential ingest, not bursty, high-concurrency loads. The P40498-B21 excels when paired with proper NVR-side buffering and RAID 5/6 striping across multiple units.

Technical Highlights:

• 0.8 DWPD Endurance + 58.5K Random Read IOPS: Real-world surveillance workloads (4–8 simultaneous 1080p30 streams) generate 40–50GB/day writes. That's less than 7% of the DWPD budget, leaving headroom for spikes and multi-stream failover. The 58.5K read IOPS matters during playback scrubbing across a 30-day rolling buffer—no lag when jumping between timestamps in your VMS timeline.
• 3.37W Power, 7mm Height: In compact edge appliances or weatherproof outdoor pods, every watt counts. Minimal thermal signature means passive cooling is viable, and the slim profile slides into SFF bays without bulky adapters. Thermal throttling is unlikely even in poorly ventilated enclosures under continuous ingest.
• SATA 6G Protocol, Hot-Pluggable Design: No firmware surprises or driver hunting. Standard AHCI stack means instant recognition in any Linux NVR or HPE ProLiant. Hot-swap capability is real—pull and replace under load if your appliance firmware supports it, though not all surveillance recorders do.

Deployment Considerations:

• Watch DWPD burn-down in high-write environments: if you're recording 24/7 across 16+ camera feeds or running frequent analytics workloads, pair multiple P40498-B21 drives in RAID 5 or 6 to distribute I/O and extend service life. A single drive is undersized for enterprise-scale multi-site aggregation.
• Random write throughput (29K IOPS) is the real bottleneck in high-concurrency scenarios. If your NVR lacks write buffering or runs RAID 0 (never advisable), saturation can trigger dropped frames under peak load. Always validate with your specific NVR model and configuration.

Deploy the P40498-B21 in mid-market retail or industrial surveillance appliances where 24/7 continuous ingest is the norm and storage density matters. Pair it with RAID 5 or 6 for redundancy, monitor DWPD consumption monthly, and you'll get 3–5 years of reliable video archival without surprise failures.
