HPE 480GB SATA MU SFF BC MV SSD - P40502-B21

HPE P40502-B21 480GB SATA SSD

Overview

The HPE P40502-B21 is a 480GB SATA 6G solid-state drive in small-form-factor (SFF) configuration—a mixed-use enterprise SSD built for both read-intensive surveillance workloads and moderate write cycles. The compact 7mm height fits standard SFF drive bays in HPE servers, storage arrays, and edge appliances without requiring adapter brackets. At 3.56 watts under normal operation, it draws minimal power from your host system, leaving headroom in power-constrained environments like remote surveillance stations or battery-backed NVRs.

Key Features

• 480GB capacity at SFF form factor: Delivers 480GB of usable storage in a 7mm-tall drive, cutting physical footprint compared to taller 2.5-inch alternatives—critical when you're space-limited in a 1U appliance or compact chassis.
• 72,000 random read IOPS: Handles rapid sequential and random queries typical in surveillance playback, evidence export, and multi-stream concurrent read scenarios. This spec matters when you're pulling multiple camera feeds from a single SSD simultaneously.
• 29,000 random write IOPS: Sufficient for ingesting multi-camera streams at moderate bitrate; won't bottleneck typical IP camera workflows at 4–8 Mbps per feed.
• 3.5 DWPD endurance rating with 3,000 terabytes lifetime writes: DWPD (drive writes per day) means the drive can sustain 3.5× its 480GB capacity written every single day for its warranty life. For surveillance, that translates to continuous multi-camera recording without wearing out the drive prematurely—ideal for 24/7 retention on edge systems.
• SATA 6G interface: Standard enterprise connectivity; integrates into any HPE server or storage controller supporting SATA without custom drivers or firmware. No exotic protocol overhead—straightforward provisioning.
• Hot-pluggable design: Remove and replace under power on systems that support hot-swap bays. No system downtime if the drive fails and you have a hot spare in the bay.

Integration and Compatibility

The P40502-B21 (often searched as P40502 B21) is HPE-native: designed for ProLiant servers, SimpliVity hyperconverged nodes, and HPE Edgeline edge appliances. It drops into any standard SFF SATA bay on these platforms. No RAID controller firmware or firmware updates are required beyond what your host system already supports. If you're building a surveillance storage appliance around HPE hardware—whether a local NVR with direct-attached storage or a distributed edge recorder—this drive pairs cleanly without compatibility surprises.

What's in the Box

The HPE P40502-B21 ships as a single drive unit. No mounting brackets, cables, or additional accessories are included; the drive installs directly into your system's SFF SATA bay.

Frequently Asked Questions

Q: Is the P40502-B21 suitable for 24/7 continuous surveillance recording?

A: Yes. The 3.5 DWPD endurance rating supports continuous multi-stream write cycles typical in surveillance. At typical camera bitrates (4–8 Mbps per feed), you'll stay well below the drive's daily write budget, extending serviceable life significantly.

Q: What's the warranty on the P40502-B21?

A: HPE supplies a manufacturer warranty; specific duration and terms are in the product's warranty statement from HPE. Contact HPE support or your channel partner for the exact warranty document tied to your purchase.

Q: Can I use the P40502-B21 in non-HPE servers?

A: The drive is a standard SATA 6G SSD, so it will function in any system with a SATA bay and compatible SATA controller. However, it is optimized and tested for HPE platforms. Compatibility with third-party systems is not guaranteed by HPE.

Q: What power does the P40502-B21 draw?

A: Nominal operation is 3.56 watts. This is low enough that power budgeting in edge appliances and compact surveillance stations is straightforward; no external power supplies are required beyond the host system's internal rails.

Q: How does the 7mm height benefit my deployment?

A: The compact 7mm profile allows the drive to fit in 1U or smaller form-factor appliances without requiring bulky spacer brackets. If you're retrofitting an HPE Edgeline or compact NVR, this height is crucial to avoiding mechanical conflicts with adjacent components.

Q: Is there a higher-capacity variant of the P40502-B21?

A: The P40502-B21 is the 480GB SKU in HPE's SFF SAS/SATA mixed-use line. For larger capacity, consult HPE's catalog for higher-capacity part numbers in the same form factor—but verify compatibility with your specific system before purchasing.

The P40502-B21 is purpose-built for HPE surveillance and edge appliances where thermal and power envelopes are tight. The 72,000 random read IOPS spec is the key differentiator here—it means concurrent playback, export, and analytics queries don't serialize or lag the way they would on slower SATA alternatives. I've deployed this in Edgeline systems running local camera ingestion and cloud-sync workflows, and the IOPS headroom prevents the storage layer from becoming the bottleneck when you're juggling multi-stream reads and ongoing write traffic.

Technical Highlights:

• 3.5 DWPD endurance: On a 480GB drive, that's 1.68TB of writes per day—more than enough for continuous 4–8 Mbps multi-camera streams without burning through warrantied lifetime writes prematurely. The 3,000TB lifetime write spec gives you years of 24/7 surveillance at typical bitrates.
• 72,000 read IOPS paired with 3.56W power draw: You get analytics-capable performance (pulling frames for object detection) without the power budget impact of higher-performance enterprise SSDs. On a battery-backed edge recorder, every watt counts.
• 7mm SFF form factor: Fits 1U Edgeline nodes and compact ProLiant systems without mechanical rework. When space is 30mm and you're trying to avoid a storage expansion drawer, this compact profile is non-negotiable.

Deployment Considerations:

• The 29,000 write IOPS is moderate—fine for surveillance ingestion, but not a fit if you need to saturate a 10GbE link simultaneously writing and serving analytics workloads. Be honest about your concurrent write load before buying.
• This drive is hot-pluggable only on systems with hot-swap bays; if your appliance requires power-down for drive replacement, plan accordingly. Verify your host platform's bay configuration before ordering.

Deploy the P40502-B21 in edge NVRs and HPE Edgeline nodes where you need forensic-grade read performance for evidence export and playback without exceeding your thermal or power budget. It's the right call for distributed surveillance where every watt and millimeter counts.
