HPE 8TB 6G SATA 7.2K LFF 512E LP MDL HDD - 834028-B21

HPE 834028-B21 8TB 6G SATA 7.2K LFF Midline Hard Drive

Overview

The HPE 834028-B21 is an 8TB Large Form Factor (LFF) SATA midline hard drive built for high-capacity, cost-sensitive server storage workloads — bulk data repositories, backup targets, archival tiers, and surveillance video retention where sequential write endurance and raw capacity matter more than peak IOPS. At 7,200 RPM over a 6Gb/s SATA interface with 512e Advanced Format sector emulation, it slots into HPE ProLiant Gen8 and later servers that accept LFF hot-plug or non-hot-plug drive bays. If you're sizing storage for a multi-camera NVR deployment or a secondary data tier in a rack environment, the 834028-B21 (often searched as 834028 B21) is the native HPE option that carries factory firmware validation and ships as a Low Profile (LP) carrier-equipped midline unit.

Key Features

• 8TB Raw Capacity: Eight terabytes per spindle keeps cost-per-GB low on bulk storage builds. A four-drive LFF bay fills to 32TB usable before RAID overhead — practical for 30- to 90-day video retention on mid-sized camera deployments without reaching for an all-flash tier.
• 6Gb/s SATA Interface: SATA III throughput is more than sufficient for sequential surveillance and archival workloads — sustained read/write speeds on midline drives are bandwidth-bound by the spindle, not the interface. You won't saturate 6Gb/s at 7.2K RPM, but the headroom ensures the controller is never the bottleneck.
• 7,200 RPM Spindle Speed: The 7.2K class sits between 5,400 RPM nearline (lower sequential throughput) and 10K/15K SAS (higher cost, higher power). For continuous write workloads like NVR recording or log aggregation, 7,200 RPM delivers workable sequential throughput without the premium of enterprise SAS.
• 512e (Advanced Format) Sector Emulation: Physical 4K sectors with 512-byte emulation means the drive communicates in 512-byte logical sectors — preserving compatibility with legacy OS and firmware stacks — while the underlying 4K physical format improves error correction density. Verify your NVR or server OS supports 512e if you're running an older stack; most ProLiant-era firmware handles it transparently.
• LFF (3.5-inch) Form Factor: Large Form Factor bays remain standard in tower servers, 4U rack units, and external storage enclosures. LFF midline drives remain the dominant bulk-storage choice in HPE ProLiant ML and DL platforms with large-bay configurations — no adapter bracket required in native LFF cages.
• Low Profile (LP) Carrier: Ships with the HPE Low Profile drive carrier rather than the Standard Carrier. Match this to your chassis carrier spec before ordering — LP and Standard carriers are not interchangeable in HPE hot-plug backplanes. Most Gen9/Gen10 LFF hot-plug chassis use the LP carrier, but confirm your system's part number against HPE's QuickSpecs for your server model.
• Midline (MDL) Endurance Rating: Midline HDDs are rated for lighter duty cycles than enterprise SAS nearline drives — appropriate for write-once/read-rarely archival, backup, and surveillance tiers, not transactional databases or high-random-IO workloads. Matching the drive class to the workload extends service life and keeps acquisition cost in line with the application.
• 1-Year Limited Warranty: HPE's 1-year limited warranty covers manufacturing defects. For extended coverage in production environments, HPE Care Pack options can extend this — evaluate total cost of ownership against the drive's workload profile before committing to large-quantity installations without coverage extension.

Integration & Compatibility

The 834028-B21 is designed for HPE ProLiant servers with 6G SATA LFF drive bays — including select Gen8, Gen9, and Gen10 DL, ML, and SL platforms. Always cross-reference against the HPE SPOCK (Single Point of Connectivity Knowledge) database for your specific server model and firmware revision to confirm supported drive configurations. The LP carrier is the standard for Gen9/Gen10 hot-plug LFF backplanes; if you're populating a Gen8 chassis, verify carrier compatibility before deploying at scale. For network video recorders and surveillance storage servers, this drive pairs naturally with HPE's ProLiant storage-optimized platforms — the capacity tier aligns with multi-stream continuous recording. See the full HPE server and storage catalog for compatible platforms. If you're building out a PoE-powered camera infrastructure alongside the storage layer, review our PoE switch selection to right-size the network feed. For storage planning guidance, the storage and retention planning guide helps correlate camera count, resolution, and retention days to raw capacity requirements.

Frequently Asked Questions

Q: What servers is the HPE 834028-B21 compatible with?

A: The 834028-B21 is designed for HPE ProLiant servers with 6G SATA LFF drive bays, including select Gen8, Gen9, and Gen10 DL, ML, and SL platforms. Always verify compatibility against HPE's SPOCK database for your specific server model and firmware revision before deploying.

Q: What is the difference between the LP (Low Profile) carrier and the Standard carrier?

A: The Low Profile carrier is a specific HPE drive tray form factor used in most Gen9 and Gen10 LFF hot-plug backplanes. It is not interchangeable with the HPE Standard Carrier. Confirm your chassis carrier spec — check your server's QuickSpecs or existing installed drives — before ordering to avoid a mismatch.

Q: What does 512e mean on this drive, and does it affect compatibility?

A: 512e (512-byte emulation) means the drive uses 4K physical sectors internally but presents 512-byte logical sectors to the host. Most modern server OS versions and HPE firmware handle 512e transparently. If you're running a legacy OS or older NVR appliance firmware, verify 512e support before deploying — some older stacks require a firmware update.

Q: Is the 834028-B21 suitable for surveillance or NVR recording workloads?

A: Yes. The midline (MDL) classification and 7,200 RPM spindle speed are well-suited to sequential-write surveillance workloads. At 8TB per drive, it provides practical capacity for multi-camera continuous recording. It is not rated for high-random-IO transactional workloads — match the drive class to the application for reliable service life.

Q: What warranty does the 834028-B21 carry?

A: The 834028-B21 carries a 1-year limited warranty from HPE. Extended coverage is available through HPE Care Pack options if your deployment requires longer hardware support terms.

Q: What is the physical size and weight of the 834028-B21?

A: The drive measures 2.61 x 10.55 x 15.66 cm and weighs 1.36 kg (approximately 3.0 lbs). These are standard LFF 3.5-inch drive dimensions — plan rack weight accordingly when populating high-density storage shelves at full capacity.

The HPE 834028-B21 is a straightforward capacity play — 8TB on a 7,200 RPM SATA midline spindle in an LFF form factor. Where I see this unit deployed most is in ProLiant-based NVR builds and backup-target configurations where you need bulk sequential storage at the lowest reasonable cost per terabyte, and where the HPE smart array controller's native drive validation matters for support continuity. It's not a drive you choose for IOPS; you choose it because your recording or archival workload is bandwidth-bound and sequential, and 8TB per bay keeps the drive count manageable.

Technical Highlights:

• 8TB LFF Capacity: At LFF density, four bays gives you 32TB raw — enough for 30+ days of retention on a 16-camera HD deployment at typical compression settings, without moving to a multi-shelf expansion unit.
• 512e Advanced Format: The 4K physical / 512-byte emulated sector layout improves on-disk ECC density compared to legacy 512n drives of the same capacity class. On supported HPE ProLiant platforms, the controller handles the 512e translation transparently — no manual alignment steps needed in most ProLiant RAID configurations.
• 1.36 kg per Drive: At 1.36 kg each, fully populated LFF storage shelves add up fast — a 24-bay 2U shelf fully loaded with these drives runs roughly 33 kg of drive weight alone. Factor this into rack weight budgets and shelf rail load ratings before committing to dense configurations.

Deployment Considerations:

• Confirm the LP (Low Profile) carrier format matches your chassis before ordering at volume — Gen8 platforms often use the Standard Carrier, and swapping carriers post-delivery adds handling overhead. Check existing installed drives or HPE QuickSpecs for your exact server model.
• The 1-year limited warranty is shorter than the 3- or 5-year coverage on HPE enterprise SAS drives. For deployments where drive replacement labor is expensive (remote sites, hardened enclosures), evaluate whether a Care Pack extension is worth the incremental cost at the time of purchase — retrofitting coverage later costs more.

The 834028-B21 is the right drive for a ProLiant-based surveillance storage server or backup appliance where you're filling LFF bays with capacity-optimized midline HDDs — not a transactional database tier, not a primary VM datastore, but a solid sequential-write workhorse for the workloads it was sized and validated for.
