HPE 6.4TB NVME MU E3S EC1 PS1030 SSD - P70401-B21

HPE P70401-B21 6.4TB NVMe Gen5 E3.S SSD

Overview

The HPE P70401-B21 is a 6.4TB NVMe Gen5 SSD in the E3.S form factor, engineered for enterprise-class storage expansion in HPE ProLiant servers and storage arrays. This drive delivers the speed and capacity needed for high-throughput database workloads, real-time analytics, and surveillance recording systems that demand sustained sequential and random I/O performance without throttling.

Key Features

• 6.4TB capacity: Stores 6.4 terabytes of raw data — for surveillance systems, that translates to roughly 400–600 hours of 4K video or 1,200–1,800 hours of 1080p footage depending on bitrate and codec. A single drive eliminates the need to stripe multiple smaller SSDs for mid-size recorder arrays.
• NVMe Gen5 interface: PCIe Gen5 protocol delivers up to 14,000 MB/s theoretical bandwidth — roughly 7–10× faster than SATA drives. Critical when you're ingesting streams from 16+ cameras simultaneously into a single storage tier; bottlenecks move from the drive into your application layer where they're easier to debug.
• E3.S form factor: Designed for HPE ProLiant Gen11 servers and newer, as well as HPE enterprise storage arrays. Fits in standard 2.5-inch hot-swap bays without adapter cards — plug-and-play replacement without downtime on redundant systems.
• Enterprise-grade reliability: Built to HPE specifications for 24/7 continuous operation in data centers and always-on surveillance architectures. Rated for sustained workloads that consumer or mid-range drives cannot tolerate without throttling or failure.
• Backward compatibility: Works in any HPE ProLiant system with NVMe Gen5 support. Verify your server's BIOS generation and storage controller firmware before deploying — not all HPE legacy systems recognize Gen5 drives without firmware updates.
• Hot-swap capability: Replacement without server shutdown on redundant RAID arrays — essential for 24/7 surveillance or mission-critical recording systems where downtime is measured in lost incident footage.

Integration & Compatibility

The P70401-B21 integrates into any HPE ProLiant or storage system with NVMe Gen5 slots. Confirm your server supports Gen5 NVMe drives; Gen10 and Gen11 systems with the correct storage controller typically support this drive, but Gen9 and older systems will not recognize it without significant hardware upgrade. Firmware updates on your storage controller may be required to unlock full performance. For surveillance or NVR applications, pair this drive with an HPE ProLiant configured with RAID 6 or RAID 10 for redundancy — a single 6.4TB failure in a non-redundant configuration means total data loss.

What's in the Box

The P70401-B21 ships as a factory-new drive with no additional hardware. Installation requires a compatible HPE ProLiant server or storage array with an available NVMe Gen5 slot; standard M.2 mounting hardware is not required — the drive slides directly into the E3.S carrier slot.

Frequently Asked Questions

Q: Is the P70401-B21 compatible with my HPE ProLiant Gen10 server?

A: Compatibility depends on the specific Gen10 controller and BIOS revision. Some Gen10 servers with NVMe-capable storage controllers support Gen5 drives, but many do not without a firmware update. Check your server's storage controller documentation or contact HPE support with your server serial number before purchasing.

Q: What is the warranty on the P70401-B21?

A: Warranty terms are provided by HPE at the time of purchase or through your reseller. Consult the paperwork or product documentation from your sourcing channel for exact coverage duration and terms.

Q: Can I use the P70401-B21 as a boot drive?

A: Yes, the drive can serve as a boot device in compatible HPE systems. Ensure your BIOS is set to boot from NVMe and that the drive is installed in a slot configured for boot support — not all NVMe slots in every server are bootable.

Q: How does NVMe Gen5 compare to Gen4 for surveillance recording?

A: Gen5 drives reduce latency and allow higher concurrent write streams without performance degradation. For systems with 16+ cameras writing simultaneously, Gen5 provides headroom; for smaller installations (4–8 cameras), Gen4 typically suffices unless you also run heavy analytics or database queries on the same array.

Q: What RAID configuration should I use with the P70401-B21?

A: RAID 6 (two-parity) or RAID 10 (mirrored striping) are standard for surveillance systems. RAID 6 offers better capacity efficiency; RAID 10 offers better write performance. Single-drive configurations (no RAID) mean any failure equals total data loss — not recommended for critical surveillance.

Q: Is there a surveillance-specific version of this drive?

A: No — the P70401-B21 is an enterprise NVMe drive. Surveillance-specific drives (e.g., Seagate SkyHawk, WD Purple) are typically SATA and optimized for 24/7 streaming on budget systems. If you're deploying this HPE drive, you're already at the enterprise tier — optimize for redundancy, not for a surveillance-tuned firmware.

The P70401-B21 is purpose-built for enterprise surveillance arrays that demand consistent, high-throughput performance without the thermal throttling or write-stall behavior you'd see in consumer or mid-range enterprise drives. The 6.4TB capacity and Gen5 NVMe interface on the P70401-B21 eliminate a common bottleneck in large-scale deployments: you can ingest 16+ simultaneous camera streams (ranging from 4–20 Mbps each, depending on resolution and bitrate) without the storage layer becoming a constraint.

Technical Highlights:

• 6.4TB capacity in E3.S form factor: Single-drive replacement for multiple smaller SSDs; no striping complexity needed for mid-to-large NVRs. Stores 400–600 hours of 4K video or 1,200–1,800 hours of 1080p depending on codec and bitrate — meaningful for archive-tier storage on premises.
• NVMe Gen5 (PCIe Gen5) interface: Theoretical bandwidth of 14,000 MB/s keeps latency flat during sustained multi-stream writes. Consumer Gen4 drives start thermal throttling at 20–30% duty cycle; enterprise Gen5 drives maintain rated IOPS and throughput across 24/7 workloads.
• E3.S hot-swap slot: Drop-in replacement on redundant RAID arrays without downtime. Matters for 24/7 surveillance — if a drive starts failing, you swap it while the array stays live; no scheduled maintenance window required.

Deployment Considerations:

• Verify NVMe Gen5 support on your target HPE ProLiant before purchase. Gen10 and Gen11 systems with NVMe controllers typically support this drive, but Gen9 and earlier do not. A firmware update on your storage controller may unlock Gen5 support even on older servers — check HPE's driver portal with your specific server model and storage controller revision.
• Pair this drive with RAID 6 or RAID 10 for redundancy. A single 6.4TB failure in a non-redundant configuration erases months of surveillance footage. The cost of a second drive and the RAID overhead is negligible compared to the liability of a complete data loss.

Deploy the P70401-B21 in mid-to-large enterprise surveillance systems where you're already using HPE ProLiant servers as NVRs or hot-storage tiers. This drive is overkill for small branch offices or edge cameras, but it's the right fit for a central recording facility managing 30+ camera streams or for a high-speed video analytics tier that needs sustained random-read performance to support detective queries across months of footage.
