HPE P58236-B21 480GB SATA Read Intensive Solid State Drive

Overview

The HPE P58236-B21 is a 480GB SATA 6Gbps 2.5-inch read-intensive solid state drive built for server environments where sequential and random read workloads dominate — think surveillance NVR storage tiers, log repositories, and read-heavy database secondaries. At 3.75W active draw and hot-plug support, it fits neatly into HPE ProLiant and Apollo platforms without requiring a maintenance window to swap or expand capacity.

Key Features

• 480GB SATA 6Gbps Interface: SATA 6Gbps provides a broadly compatible, cost-effective path into HPE server bays — no HBA or NVMe backplane required. For solid state drives in read-intensive roles, SATA delivers more than sufficient sequential bandwidth. If you need NVMe-class latency for transactional workloads, this is not that drive — but for surveillance replay, log reads, and analytics queries, 6Gbps is not the bottleneck.
• 73,183 Random Read IOPS (4KiB, Q=16): At queue depth 16, this drive sustains over 73K read IOPS — enough to handle concurrent stream playback from dozens of cameras or serve multiple analytical queries simultaneously without stalling. Peak burst reaches 79,702 IOPS at Q=128, which matters when NVR software bursts into deep backlogs during motion-event retrieval.
• 45,284 Random Write IOPS (4KiB, Q=16): Write performance peaks at 47,820 IOPS at Q=4, which aligns with the write pattern of surveillance and logging workloads — short, sequential writes rather than deep-queue random IO. The drive is tuned for read dominance; don't deploy it in write-heavy transactional roles where endurance will erode faster than the workload rating supports.
• Hot-Plug Capable: Hot-plug support means failed drives swap out without powering down the server — critical in always-on surveillance environments or co-located NVR racks where taking a system offline costs recorded footage or triggers compliance gaps. Pair with a compatible network video recorder or HPE server with an appropriate drive bay cage for full hot-swap benefit.
• 3.75W Active Power Draw: Under 4W per drive makes high-density deployments practical — a 24-bay chassis running these SSDs draws roughly 90W for storage alone, well within typical server PSU headroom. Lower per-drive wattage also reduces cooling load in sealed rack enclosures common in remote surveillance installations.
• 1,324 TBW Lifetime Writes: At 1,324 terabytes written total, this drive is sized for workloads where reads dominate and writes are relatively modest. For a typical 16-camera NVR writing at ~2TB/day, that endurance budget spans years of continuous operation — but model your actual write rate before deploying in higher-density write environments.
• 2.5-Inch Small Form Factor: The 2.5-inch form factor slots into the vast majority of HPE Gen9/Gen10/Gen10 Plus server bays and HPE-compatible storage enclosures without a tray adapter. Consult HPE's server compatibility matrix for your specific chassis to confirm the drive bay configuration before ordering.

Integration and Compatibility

The P58236-B21 (often searched as P58236 B21) is an HPE-branded OEM drive designed for use in HPE ProLiant, Apollo, and Synergy platforms. Compatibility is validated against HPE's Smart Array and dynamic smart array controllers — use HPE's online configurator or the server's QuickSpecs to confirm support for your specific platform and firmware revision. For network infrastructure planning alongside storage expansion, verify that your NVR or server platform's backplane supports SATA 6Gbps hot-plug at the bay you intend to populate.

Frequently Asked Questions

Q: What server platforms is the HPE P58236-B21 compatible with?

A: The P58236-B21 is an HPE OEM SATA SSD designed for HPE ProLiant, Apollo, and Synergy server families. Verify compatibility for your specific server generation and chassis bay configuration using HPE's server QuickSpecs or the HPE SPOCK compatibility tool before deploying.

Q: Is the P58236-B21 hot-plug capable?

A: Yes. The P58236-B21 supports hot-plug operation, meaning you can insert or remove the drive while the server remains powered on — provided the chassis and controller support hot-plug on that bay. This is critical for surveillance and always-on storage environments where downtime is not acceptable.

Q: What is the endurance rating (TBW) for the P58236-B21?

A: The P58236-B21 is rated for 1,324 terabytes written (TBW) over its lifetime. For a read-intensive workload profile — such as surveillance recording with periodic playback — this endurance budget is well-matched. High-write transactional workloads will exhaust endurance faster and should use a mixed-use or write-intensive rated drive instead.

Q: What are the peak random read IOPS for this drive?

A: At queue depth 16 with 4KiB blocks, the P58236-B21 delivers 73,183 random read IOPS. At the maximum tested queue depth of 128, peak read IOPS reach 79,702 — relevant when NVR or analytics software bursts into deep read queues during event retrieval or motion search.

Q: What is the power consumption of the P58236-B21?

A: Active power draw is 3.75W. This low per-drive wattage makes it practical for high-density storage configurations without straining server PSU capacity or thermal headroom, particularly in sealed rack environments typical of remote surveillance deployments.

Q: Is the P58236-B21 suitable for write-heavy workloads like transactional databases?

A: No. This is a read-intensive drive rated and tuned for workloads where reads dominate. Random write IOPS peak at 47,820, which is adequate for surveillance-class write patterns but not optimal for high-concurrency transactional write workloads. For those use cases, select an HPE mixed-use or write-intensive SSD instead.

James Everett

The P58236-B21 lands in the right place for integrators speccing storage into HPE-based NVR or edge server builds — 73,183 random read IOPS at Q=16 is more than sufficient for multi-stream concurrent playback, and the 3.75W draw means you're not fighting the PSU budget when you're stacking eight or twelve of these in a 2U chassis. The read-intensive positioning is the defining characteristic here: endurance is rated at 1,324 TBW, which maps cleanly to write-light, read-heavy profiles.

Technical Highlights:

• 73,183 Read IOPS @ Q=16: Sustains concurrent read throughput across multiple NVR channels or analytics streams without queue starvation — peak bursts to 79,702 IOPS at Q=128 for deep event-retrieval operations.
• Hot-Plug Support: Drop-in drive replacement without a server shutdown — essential in live surveillance infrastructure where pulling a system offline means a gap in recorded coverage or a compliance flag.
• 3.75W Active Draw: Dense configurations (12–24 bays) stay within standard HPE redundant PSU budgets without thermal surprises; meaningful in sealed remote rack installs with limited cooling capacity.

Deployment Considerations:

• Confirm bay-level hot-plug support on your specific HPE chassis and controller firmware before relying on hot-swap capability — not all backplane configurations enable it even when the drive supports it.
• The 1,324 TBW endurance fits read-dominant workloads well, but if your deployment writes more than ~2–3TB/day per drive (high-density camera recording at high bitrate), model the endurance carefully — this drive is not sized for heavy write duty cycles.

Best fit: HPE ProLiant-based NVR deployments, edge AI inference servers with large model-read workloads, and log-tier storage in security operations centers where read latency and IOPS matter more than raw write throughput.
