HPE 15.3TB NVME RI E3S EC1 PM1743 SSD - P57807-B21

HPE P57807-B21 15.36TB NVMe PCIe 5.0 EDSFF E3.S Read-Intensive SSD

Overview

The HPE P57807-B21 is a 15.36TB hot-swap solid-state drive built around the EDSFF E3.S form factor and a PCIe 5.0 NVMe interface — a combination that targets the next generation of high-density compute and storage platforms where bandwidth-hungry workloads need both capacity and low latency in a smaller physical footprint than a 2.5-inch drive. If your deployment involves AI inference, database acceleration, or large-scale surveillance data repositories that must stream footage faster than conventional SAS or SATA SSDs allow, this is the drive architecture to evaluate. The P57807-B21 (often searched as P57807 B21) ships bundled with the HPE E3.S Thin Carrier, meaning it arrives ready to slot into compatible HPE server bays without hunting down a separate adapter.

This unit is refurbished with a 90-day Server Supply warranty. No manufacturer warranty applies. Factor that into your total cost of ownership calculation before deploying in environments with uptime SLAs that require longer coverage.

Key Features

• PCIe 5.0 NVMe Interface: PCIe Gen 5 doubles the per-lane bandwidth of Gen 4 — meaning the controller fabric feeding this drive is no longer the bottleneck. In multi-drive NVMe deployments backing real-time analytics or parallel video ingest, that headroom translates to sustained throughput rather than burst peaks that flatten under load.
• 197,931 / 1,060,146 IOPS 4K Random Read (Steady-State / Maximum): Steady-state reads at ~198K IOPS are the number to use when sizing a storage pool for a continuous-read workload like video retrieval or database query serving. The burst ceiling of 1.06 million IOPS is relevant for cache-tier applications — but do not design an architecture around peak figures unless your controller can actually sustain that queue depth.
• 359,542 / 363,570 IOPS 4K Random Write (Steady-State / Maximum): The write IOPS gap between steady-state and max is unusually tight at under 1.1%, which indicates consistent write latency. For write-heavy logging or event-recording pipelines, flat write performance means predictable queue depth and fewer buffering stalls.
• 28,032 TBW Endurance at 1 DWPD: At 1 Drive Write Per Day, total endurance is rated to 28,032 TB written over the drive's lifetime. For a surveillance recording server writing, say, 2–3 TB per day per drive, that rating implies roughly 25+ years of write life at 1 DWPD — effectively not the limiting factor in your refresh cycle.
• EDSFF E3.S Form Factor: E3.S is purpose-designed for high-density rack storage — thinner than a 2.5-inch drive, with a longer connector life cycle and better thermals for tightly packed drive bays. If your HPE server supports E3.S bays, this format allows more drives per unit of rack space than traditional form factors.
• Hot-Swap Support: Hot-swap capability means you can replace a failed or flagged drive without taking the system offline — critical for 24/7 surveillance storage nodes or AI compute clusters that cannot tolerate scheduled maintenance windows.
• 24.6W Power Consumption: At 24.6 watts, this drive runs warmer than a 2.5-inch SATA SSD but delivers substantially higher IOPS per watt than a comparable spinning disk. Verify your server's per-bay power budget and airflow path before populating multiple E3.S bays at full density — thermal management at scale matters with this drive class.
• Bundled HPE E3.S Thin Carrier: The included carrier eliminates the risk of sourcing an incompatible adapter separately and confirms the drive was spec'd and packaged for HPE platform integration from the start.

Integration and Compatibility

The P57807-B21 targets HPE server platforms with EDSFF E3.S compatible drive bays and PCIe 5.0 capable storage controllers. Confirm your specific server model and firmware version support E3.S hot-swap backplanes before ordering — not all HPE Gen10/Gen11 platforms include E3.S bays without a specific riser or backplane option. For server storage deployments requiring maximum sequential read throughput, this drive pairs naturally with HPE's NVMe-oF capable storage controllers. If you are building out a network video recorder or surveillance storage backend that must handle dozens of concurrent 4K streams, the read IOPS profile here is well-suited to parallel retrieval workloads. For enterprise buyers evaluating the broader HPE storage and server line, the PM1743 series sits at the high-performance end of HPE's read-intensive SSD portfolio. Organizations managing large-scale video surveillance infrastructure should also evaluate compatible PoE switches and edge recording devices that feed data into this storage tier. Buyers comparing NVMe SSD options should review a storage selection guide to match drive endurance class and interface generation to actual workload write patterns before committing to a capacity tier.

Frequently Asked Questions

Q: What form factor is the HPE P57807-B21 and which server bays does it fit?

A: The P57807-B21 uses the EDSFF E3.S form factor. It requires a compatible E3.S hot-swap bay in your HPE server. Verify your specific server model's backplane and controller support before ordering — not all HPE Gen10 or Gen11 platforms include E3.S bays by default.

Q: What warranty applies to the P57807-B21?

A: This unit is sold as refurbished with a 90-day Server Supply warranty. No manufacturer warranty applies. If your deployment requires a longer coverage period, factor in extended service agreements separately before purchasing.

Q: What is the endurance rating of the P57807-B21?

A: The drive is rated at 1 Drive Write Per Day (DWPD) with a total endurance of 28,032 TB written. For most surveillance and read-intensive enterprise workloads, 1 DWPD is appropriate — if your use case involves heavy sequential writes all day, evaluate a mixed-use or write-intensive class instead.

Q: Does the P57807-B21 support hot-swap?

A: Yes, the drive supports hot-swap operation, allowing replacement without powering down the server — provided the host system and backplane also support hot-swap for E3.S drives.

Q: What is the read IOPS performance of the P57807-B21?

A: Steady-state 4K random read performance is rated at 197,931 IOPS. Maximum (burst) 4K random read reaches 1,060,146 IOPS. Use the steady-state figure for workload sizing; the maximum figure is relevant only for cache-tier or burst-read scenarios where the queue depth can be fully exploited.

Q: What is included in the box with the P57807-B21?

A: The P57807-B21 ships bundled with the HPE E3.S Thin Carrier, which allows direct installation into compatible HPE server E3.S bays without a separate adapter.

Ted Perry

The P57807-B21 is one of those drives that looks impressive on paper and mostly delivers — 15.36TB in an E3.S sled with a PCIe 5.0 interface and a steady-state read ceiling of 197,931 IOPS puts it squarely in the high-density, read-intensive tier that surveillance storage architects have been waiting on. The endurance story at 28,032 TBW on a 1 DWPD rating is strong for the workload class it targets.

Technical Highlights:

• 1,060,146 IOPS Burst Read: That burst ceiling is real but context-dependent — you need a controller that can actually drive the queue depth required to sustain it. In most NVMe-oF or direct-attach configurations, you will land closer to the 198K steady-state figure under continuous multi-stream load, which is still more than sufficient for parallel 4K surveillance retrieval across dozens of channels.
• 28,032 TBW at 1 DWPD: For a surveillance node writing 2–3 TB per day across a multi-drive array, this endurance class is not the constraint. The 90-day refurbished warranty is the real risk variable to account for in total cost of ownership — not the NAND endurance.
• 24.6W Power per Drive: In a fully populated E3.S bay configuration, thermal density climbs fast. At 24.6W per drive, a 24-drive chassis draws nearly 590W in storage alone — confirm your server's airflow design and per-bay power budget before committing to full density.

Deployment Considerations:

• E3.S backplane compatibility is not universal across HPE Gen10/Gen11 — verify the specific server SKU's storage configuration options and that the backplane firmware supports PCIe 5.0 negotiation with the PM1743 controller before finalizing a purchase order.
• This is a refurbished unit with a 90-day warranty only. For production surveillance or AI inference deployments with uptime requirements, budget for either spare drives on the shelf or a service contract — the lack of manufacturer coverage is the primary risk, not the drive's performance profile.

Best fit: high-density NVMe storage nodes in HPE Gen11 platforms serving large-scale video surveillance archives, AI inference data pipelines, or database read pools — environments where E3.S density and PCIe 5.0 bandwidth matter and the refurbished condition can be managed with a spares strategy.
