The HPE P79620-B21 is a 30.72TB NVMe Gen5 solid-state drive in EDSFF E3.S form factor, engineered for high-capacity surveillance and data center storage deployments where read-heavy workloads dominate. Built on QLC 3D NAND architecture with self-encrypting capabilities, this drive targets systems requiring dense, secure, and power-efficient storage without sacrificing sequential read performance.
The 30.72TB capacity per drive reduces rack density overhead in large-scale surveillance systems. A single HPE ProLiant server populated with eight P79620-B21 drives delivers 245.76TB of raw capacity — sufficient for 30+ concurrent 4K streams recorded at 24/7 retention of 60+ days depending on compression and scene complexity. The NVMe interface ensures video metadata queries and analytics-driven playback remain responsive even under heavy concurrent load.
Self-encryption is essential for systems processing sensitive security footage in multi-tenant or regulated environments. Hardware-based encryption avoids the CPU tax of software full-disk encryption, preserving transcoding and analytics performance on surveillance appliances.
QLC NAND delivers cost efficiency per terabyte but carries finite write endurance. Surveillance workloads with continuous sequential writes and high frame rate ingest can accumulate drive writes quickly — verify write budget against your specific retention policy and number of cameras before committing to production scale. Mixed read/write surveillance systems may benefit from TLC variants if write cycles exceed drive specifications.
The EDSFF E3.S form factor is HPE-proprietary for server applications — ensure your storage appliance or NVR explicitly supports this formfactor and NVMe Gen5 PCIe slot configuration. Legacy systems designed for 2.5-inch SAS or SATA cannot use this drive without a complete platform migration.
The P79620-B21 ships as a bare drive; mounting, thermal management, and interface adapters (if needed) are supplied separately by the appliance manufacturer or server integrator.
Q: Is the P79620-B21 compatible with Milestone XProtect or other third-party VMS platforms?
A: The P79620-B21 is a raw storage device; compatibility depends on the surveillance appliance or NVR server that houses it. Verify your target server or appliance model supports NVMe Gen5 and the EDSFF E3.S form factor before purchase.
Q: What is the warranty on the P79620-B21?
A: Warranty details are not provided in the available product documentation. Contact HPE directly or your reseller for coverage terms and duration.
Q: Can I use the P79620-B21 in a 2.5-inch or 3.5-inch server bay?
A: No. The EDSFF E3.S form factor is distinct from 2.5-inch or 3.5-inch drives. Your server or appliance must have a dedicated EDSFF slot to accommodate this drive. Check your hardware documentation before ordering.
Q: What is the endurance rating (TBW) for the P79620-B21?
A: Endurance specifications are not listed in the available product information. QLC NAND typically offers lower write cycles than TLC or SLC; request the detailed datasheet from HPE to confirm TBW (terabytes written) for your write-heavy surveillance workload.
Q: Does self-encryption impact read or write performance?
A: Hardware-based self-encryption (SED) on the P79620-B21 offloads encryption to the drive's controller, avoiding CPU overhead. Performance impact is negligible compared to software encryption, making it ideal for appliances running concurrent video analytics and transcoding.
Q: How does QLC NAND compare to TLC for surveillance recording?
A: QLC NAND delivers higher capacity and lower cost per TB, but with reduced write endurance. For read-heavy playback and analytics workloads, QLC is cost-effective. For systems with extremely high frame-rate ingest or write-heavy indexing, verify the drive's TBW rating matches your continuous write profile.

I've built surveillance systems on the HPE ProLiant platform for years, and the P79620-B21 represents a real step forward for facilities running 24/7 multi-camera recording with demanding playback and analytics requirements. The 30.72TB capacity per drive means you're consolidating what used to require four or five smaller drives into a single, power-efficient NVMe Gen5 slot — that density advantage alone justifies the platform upgrade if you're still running legacy 2.5-inch SAS arrays.
Technical Highlights:
Deployment Considerations:
The P79620-B21 is the right pick for large-scale surveillance buildouts where you need extreme density, hardware encryption, and the throughput headroom to run analytics without blocking playback — especially if you're replacing older SATA NVR infrastructure and want to cut power and cooling costs. Skip it if you're building a small facility (under 50TB raw capacity) or need absolute maximum write durability; cost per TB advantage shrinks on small systems, and TLC variants with higher endurance make more sense there.
