Lenovo 4XB7A80526 ST50 3.5 2TB 7.2K Non-hs SATA HDD REP

Lenovo 4XB7A80526 ST50 3.5" 2TB 7.2K SATA Non-Hot-Swap Server Hard Drive

Overview

The Lenovo 4XB7A80526 is a 2TB, 7,200 RPM SATA hard drive built specifically for the Lenovo ThinkSystem ST50 tower server. At 3.5 inches and running a 6 Gb/s SATA interface, it delivers the sequential throughput and capacity headroom that small-to-midsize workloads — file serving, surveillance recording, light virtualization — actually need, without the cost premium of SAS or the endurance overhead of enterprise SAS drives when your workload doesn't demand it. This is a non-hot-swap unit, which matters for how you plan maintenance windows.

Key Features

• 2TB Capacity at a Practical Price Point: Two terabytes gives a single ST50 node enough runway for months of surveillance footage at standard bitrates, or a substantial file-share repository without immediately needing expansion. If your retention policy calls for 30–90 days of multi-camera footage, this is a realistic starting point — though high-channel or high-resolution deployments will want to populate additional bays or upgrade to higher-capacity options.
• 7,200 RPM Spindle Speed: At 7.2K RPM this drive sustains the sequential read/write throughput that surveillance recording and bulk file transfers demand. It won't match the random IOPS of an SSD, but for write-heavy, sequential workloads like continuous camera ingestion, the spindle speed is the correct tradeoff — you get far more capacity per dollar than NAND at this tier.
• SATA 6 Gb/s Interface: The 6 Gb/s SATA III interface is native to the ST50's onboard controller, so no HBA or additional adapter is required. Real-world throughput sits well within what this interface supports, meaning the drive's mechanical speed — not the bus — is the actual bottleneck, as expected.
• 3.5" Form Factor — Maximizes Bay Capacity: The 3.5-inch form factor fills the ST50's large-format bays, delivering higher areal density per slot compared to 2.5-inch options. If you're building out storage density in a tower footprint, 3.5-inch drives are the correct choice.
• Non-Hot-Swap Configuration: This is a non-hot-swap (non-HS) drive, meaning the server must be powered down for drive installation or replacement. For environments where planned maintenance windows are acceptable — branch offices, small business server rooms, low-criticality surveillance archives — this is a workable constraint. If you need live swap capability for zero-downtime operations, you'll want to spec a hot-swap backplane and a compatible HS drive variant instead.
• Lenovo Server-Validated Hardware: The 4XB7A80526 is a Lenovo-qualified option for the ST50 platform, sourced through distribution channels that carry server-line components. Using platform-validated drives avoids the firmware and compatibility edge cases that can occur with generic retail drives in enterprise server environments — especially relevant when the ST50's storage controller enforces drive qualification lists.
• Single-Pack Quantity: Sold as a single unit (1 pc per pack), so you can buy exactly the number of drives your bay count and capacity target require, without being forced into multi-pack minimums.

Integration & Compatibility

The 4XB7A80526 is designed as a component for the Lenovo ThinkSystem ST50 server platform. The SATA 6 Gb/s interface connects directly to the ST50's onboard Intel storage controller — no additional HBA required. The 3.5-inch, non-hot-swap format requires standard large-bay drive bays; verify your ST50 chassis configuration (non-HS vs. HS backplane) before ordering. This drive is not rated or positioned for NAS enclosures, external USB enclosures, or consumer desktop systems — it is server-class hardware intended for workstation and tower server deployment.

For storage drives used in surveillance and security applications, pairing this unit with a network video recorder or a Lenovo ST50 configured as a dedicated recording server is a common deployment. If your retention requirements exceed what a single 2TB drive provides, consult your surveillance storage planning resources to calculate the correct drive count and capacity before committing to a configuration. For server accessories and rack infrastructure, the broader Lenovo server line offers compatible components.

Frequently Asked Questions

Q: Is the Lenovo 4XB7A80526 a hot-swap drive?

A: No. The 4XB7A80526 is a non-hot-swap (non-HS) drive. The server must be powered down before installing or removing this drive. If your deployment requires live drive replacement without downtime, you will need a hot-swap backplane configuration and a compatible hot-swap drive variant.

Q: What server is the 4XB7A80526 designed for?

A: The 4XB7A80526 is a Lenovo-qualified drive for the ThinkSystem ST50 tower server platform. It is intended for use as a server or workstation component, not for consumer desktop systems or NAS enclosures.

Q: What interface does the 4XB7A80526 use?

A: It uses a SATA 6 Gb/s (SATA III) interface, which is native to the ST50's onboard storage controller. No additional HBA or adapter is required for standard ST50 configurations.

Q: How much does the 4XB7A80526 weigh, and what are its dimensions?

A: The drive weighs 2.10 lb. Physical dimensions are 8.40 x 10.40 x 3.90 inches (L x W x H), consistent with a standard 3.5-inch hard drive in a server tray/carrier assembly.

Q: Can I use the 4XB7A80526 for surveillance video storage?

A: Yes, a 2TB 7,200 RPM SATA drive is well-suited for sequential write workloads like continuous surveillance recording. Actual retention duration depends on camera count, resolution, bitrate, and compression settings. For multi-camera or high-resolution deployments, calculate your storage requirements before assuming 2TB will meet your retention policy.

Q: Is this drive sold in a multi-pack or as a single unit?

A: The 4XB7A80526 is sold as a single unit (1 drive per pack), allowing you to purchase exactly the quantity needed for your bay configuration.

James Everett

The 4XB7A80526 is a straightforward spec: 2TB, 7,200 RPM, SATA 6 Gb/s, 3.5-inch non-hot-swap, Lenovo-validated for the ST50. What matters in practice is understanding where the non-hot-swap designation creates operational constraints — and where it doesn't.

Technical Highlights:

• 7,200 RPM / SATA 6 Gb/s: Sequential write throughput at this spindle speed is adequate for continuous multi-camera recording at standard bitrates. The SATA III bus won't be the bottleneck — the drive's mechanical speed is, which is expected and acceptable for this workload class.
• 2TB Capacity: At typical H.264/H.265 surveillance bitrates (2–8 Mbps per channel), 2TB supports roughly 2–9 days of single-camera continuous recording, or proportionally less across multiple channels. Size your drive count accordingly before deployment.
• 2.10 lb / 8.40 x 10.40 x 3.90 in: Standard 3.5-inch drive dimensions in a server tray — fits the ST50's non-HS bays without modification. Weight is typical for a drive at this capacity class.

Deployment Considerations:

• Non-hot-swap means a maintenance window is required for any drive swap. Plan your ST50 deployment with RAID or backup power in place if uptime is a concern — a failed non-HS drive in a single-drive config takes the system offline for replacement.
• Verify the ST50 chassis is configured for non-hot-swap bays before ordering. The ST50 ships in both HS and non-HS backplane variants; installing a non-HS drive into an HS backplane is not supported.

This drive is the right call for a Lenovo ST50 deployed as a dedicated surveillance recording node in a branch office or small facility where planned maintenance windows are feasible and budget efficiency on storage is a priority over zero-downtime swap capability.
