Lenovo 4XB7A76721 ST50 3.5 1TB Client 7.2K Non-hs SATA HD

Lenovo 4XB7A76721 ST50 3.5-Inch 1TB 7.2K Non-Hot-Swap SATA Hard Drive

Overview

The Lenovo 4XB7A76721 is a 1TB, 7,200 RPM, 3.5-inch SATA hard drive qualified for the Lenovo ThinkSystem ST50 tower server. It ships as a client-class non-hot-swap unit — meaning the server must be powered down for a drive swap — which fits deployments where the ST50 is used as a entry-level server in branch offices, small workgroups, or light NVR storage builds where planned maintenance windows are the norm and hot-swap redundancy isn't a budget priority.

At 1TB on a Lenovo server storage platform, this drive covers basic operating system, application, and moderate data workloads. For environments scaling beyond 1TB or requiring RAID redundancy across multiple drives, additional units of the 4XB7A76721 can be configured in the ST50's drive bays.

Key Features

• 1TB SATA Capacity: Enough headroom for OS, applications, and moderate local data storage on a branch or small-office ST50 — without paying for enterprise-class capacity you won't use.
• 7,200 RPM Spindle Speed: Faster than 5,400 RPM desktop-class drives; delivers noticeably snappier sequential read/write for server workloads like local file serving or light database access.
• 3.5-Inch Form Factor: Standard LFF (large form factor) bay compatibility — fits the ST50's native drive bays without adapters or conversion sleds.
• SATA Interface: Pairs directly with the ST50's onboard SATA ports; no separate HBA required for basic configurations, keeping the bill of materials clean.
• Non-Hot-Swap Design: Trade-off to understand upfront: drive replacement requires a planned shutdown. Appropriate for ST50 deployments where availability SLAs permit maintenance windows. If continuous uptime is critical, evaluate hot-swap-capable configurations instead.
• Lenovo-Qualified Component: Factory-new drive validated for the ST50 platform — reduces compatibility risk vs. sourcing generic drives that may not be on Lenovo's compatibility list.

Integration and Compatibility

The 4XB7A76721 is qualified specifically for the Lenovo ThinkSystem ST50 server. Before ordering, confirm your ST50's bay count and current drive population. The ST50 supports a limited number of 3.5-inch SATA storage drives; plan your RAID level and drive count together to avoid a mid-build shortfall. SATA interface is standard and broadly compatible, but drive firmware and platform validation are specific to the ST50 — using this drive in other server platforms is outside its verified qualification scope.

Frequently Asked Questions

Q: Is the 4XB7A76721 a hot-swap drive?

A: No. The 4XB7A76721 is a non-hot-swap drive. The ST50 server must be powered down before removing or installing this drive.

Q: What server is this drive qualified for?

A: This drive is qualified for the Lenovo ThinkSystem ST50 tower server. Compatibility with other Lenovo or third-party platforms is not verified by this listing.

Q: What is the spindle speed of the 4XB7A76721?

A: The drive spins at 7,200 RPM, which is standard for client-class 3.5-inch SATA hard drives used in entry-level server configurations.

Q: What is the form factor and interface?

A: The 4XB7A76721 uses a 3.5-inch large form factor with a SATA interface, fitting the ST50's native drive bays without additional adapters.

Q: Can I use multiple units of this drive in a RAID array?

A: Yes. Multiple units can be deployed in the ST50's available bays for RAID configurations. Confirm available bay count and your ST50's RAID controller support before ordering additional drives.

Eden Phillips

The 4XB7A76721 is a straightforward component pick for ST50 builds where the priority is platform-validated storage at 1TB capacity — the non-hot-swap design is the most important operational constraint to communicate to the end customer before the order goes in.

Technical Highlights:

• 7,200 RPM SATA: Faster than 5,400 RPM alternatives; meaningful for light server I/O workloads like local file serving or application data on an ST50 branch deployment.
• 3.5-Inch Non-Hot-Swap: LFF bay fit is clean — no sled adapters. But the non-hot-swap designation means any drive failure requires a planned outage to replace, not a live swap.
• 1TB Capacity: Adequate for single-function ST50 roles (file server, local backup target, light NVR) — if the workload is growing, price out 2TB or 4TB qualified options before committing to this capacity tier.

Deployment Considerations:

• Confirm the ST50's available 3.5-inch bay count before ordering multiples for RAID — the ST50 has a limited bay configuration and bay availability varies by chassis build.
• Non-hot-swap is a hard operational constraint: if the deployment requires any-time drive replacement without downtime, this is the wrong drive class regardless of cost savings.

Best fit for ST50 deployments in small offices or branch locations where a maintenance window for drive service is acceptable and 1TB covers the anticipated workload — not the right pick for high-availability or continuous-uptime requirements.
