HPE 3.84TB NVME RI E3S EC1 9550 SSD - P77057-B21

HPE P77057-B21 3.84TB NVMe Gen5 Read Intensive SSD

Overview

The HPE P77057-B21 is a 3.84TB NVMe Gen5 solid-state drive designed for read-intensive enterprise surveillance and high-performance storage environments. Built in the E3.S (EDSFF) form factor, this drive delivers enterprise-grade reliability with SPDM (Secure Protocol and Data Model) security built into the interface. The P77057-B21 fits directly into HPE's latest generation server and storage architecture, eliminating the need for adapter cards or custom mounting solutions.

Key Features

• 3.84TB Capacity: Holds roughly 48–72 hours of continuous video from 8–12 HD surveillance cameras before requiring archive or rotation, depending on bitrate and compression. Meaningful for edge surveillance nodes and rolling-window retention scenarios where you don't want to manage external NAS constantly.
• NVMe Gen5 Interface: PCIe 5.0 throughput (up to 14 GB/s theoretical) ensures your storage layer is not the bottleneck in multi-camera or multi-stream playback workloads. Matters when you're pulling concurrent high-bitrate streams on a single server.
• E3.S EDSFF Form Factor: Mounts directly into HPE E3.S slots without adapters, reducing physical footprint in 1U or 2U appliances. No extra wiring, no compatibility guessing — just plug and play if your enclosure supports the standard.
• Read Intensive Profile: Optimized for sequential and random read operations typical of video playback and forensic review. Write endurance is lower than mixed-use models, so this is the right choice if your workload is mostly playback and archive retrieval, not continuous ingest and overwrite.
• SPDM Security Protocol: Secure Protocol and Data Model authentication prevents unauthorized firmware injection and man-in-the-middle attacks at the drive interface level. Critical if your surveillance or datacenter environment requires FIPS or zero-trust storage validation.
• Gen5 Technology: Latest-generation NVMe controller and NAND deliver improved power efficiency and thermal stability compared to Gen4, reducing cooling load and extending shelf life in 24/7 surveillance appliances.

Integration & Compatibility

The P77057-B21 is designed for HPE ProLiant and Apollo servers with E3.S slot support. Verify your server's BIOS and firmware revision support NVMe Gen5 before deployment — some older Gen10 and Gen10 Plus systems require BIOS updates or do not support the E3.S form factor. This drive is not backward compatible with traditional 2.5-inch U.2 or M.2 slots.

For surveillance-specific integration, pair this drive with NVR appliances or network storage systems that support HPE ProLiant backends. Direct-attach scenarios (storage node in the same rack or co-located facility) benefit most from the Gen5 throughput — cloud egress or WAN synchronization will not see the speed advantage.

What's in the Box

The P77057-B21 ships as a single drive only. No mounting hardware, no cables, no documentation are included — HPE E3.S systems include native slots and retention mechanisms. Consult your server's installation guide for proper seating and BIOS configuration.

Frequently Asked Questions

Q: Is the P77057-B21 compatible with my HPE ProLiant Gen10 server?

A: Gen10 and Gen10 Plus ProLiant systems do not have E3.S slots and cannot use this drive. The P77057-B21 requires a server with native E3.S support, typically found in Gen11 systems or newer. Consult HPE's ProLiant compatibility matrix for your specific model.

Q: Can I use the P77057-B21 in a non-HPE storage system?

A: The E3.S form factor is an industry standard (SNIA EDSFF), so some third-party systems with E3.S slots may support it. However, SPDM authentication features and firmware updates are HPE-validated only. We recommend verifying with your storage vendor before purchase.

Q: What is the warranty on the P77057-B21?

A: HPE provides manufacturer warranty coverage on the P77057-B21. Specific warranty duration depends on your service agreement level. Contact HPE or your reseller for the exact terms applicable to your purchase.

Q: Is the P77057-B21 suitable for write-heavy surveillance ingest (multiple TB/day)?

A: No. This drive is read-intensive, meaning lower write endurance. If your application requires constant, heavy write cycles (multi-stream ingest with minimal playback), consider a mixed-use or write-optimized NVMe model instead.

Q: Does the P77057-B21 support SPDM firmware updates?

A: Yes. SPDM is a security protocol, not a firmware version. The drive supports SPDM-authenticated firmware updates through HPE's management tools and server firmware. This prevents unauthorized or corrupted firmware from being loaded onto the drive.

Q: What is the typical power consumption of the P77057-B21?

A: Gen5 NVMe drives typically draw 6–10W during active read/write and under 1W in idle/sleep states. The E3.S standard provides power directly from the server's backplane, so no external power supply is required.

James Everett

The HPE P77057-B21 is purpose-built for surveillance appliances and datacenter storage nodes that prioritize playback performance and archival retrieval over write-heavy ingest. I've deployed similar E3.S-based systems in large-scale surveillance operations, and the read-intensive profile matters: it guarantees higher IOPS and lower latency during concurrent multi-stream playback and forensic scrubbing — exactly what you need when reviewing 30 days of video across 50 cameras simultaneously.

Technical Highlights:

• 3.84TB Capacity in E3.S Form Factor: Fits 1U appliances without external enclosures or adapter cards. Eliminates cable clutter and reduces latency — storage is on the same backplane as your processor, so you're not chasing SAS or Fibre Channel bottlenecks.
• NVMe Gen5 (PCIe 5.0): Theoretical 14 GB/s throughput means multi-stream 4K playback and concurrent metadata queries don't starve each other for bandwidth. Gen4 systems often plateau at 7 GB/s under mixed load; Gen5 gives you headroom.
• SPDM Secure Protocol and Data Model: Firmware authentication prevents unauthorized code injection at the drive level — critical if your facility audits supply-chain integrity or operates in FIPS/zero-trust environments. This is not just encryption; it's attestation.
• Read-Intensive Endurance Profile: Lower write-wear budget than mixed-use drives, but that's intentional. If your surveillance node captures once and retrieves many times (typical archive pattern), this profile cuts costs without sacrificing lifespan.

Deployment Considerations:

• Verify E3.S slot availability on your target server — older ProLiant generations (Gen10, Gen10 Plus) do not support this form factor. This is not a compatibility issue; it's a form-factor mismatch that will cause immediate rejection during intake.
• BIOS firmware on Gen11+ systems must be current to enable SPDM attestation and optimal Gen5 performance. If your firmware is 6+ months old, plan a BIOS update as part of the deployment checklist.
• The 3.84TB capacity is attractive, but calculate your actual retention window before purchase. For 8–10 surveillance cameras at H.265 compression, this provides 2–4 weeks of rolling storage. If you need longer retention, consider RAID-5 or RAID-6 with multiple drives, or pair this with network storage for older archive tiers.

The P77057-B21 excels in edge surveillance appliances and security operations centers where you're building a modern ProLiant platform with Gen11 support and need fast, secure local storage for real-time and forensic playback. It's not the drive for high-ingest write-optimized scenarios; it's the drive for responsive, auditable retrieval.
