Lenovo 4XB7A80527 3.5" 1TB 7200RPM SATA Server Hard Drive

Overview

The Lenovo 4XB7A80527 is a 1TB, 7200RPM, 3.5-inch SATA hard drive designed as a replacement or expansion storage option for the Lenovo ThinkSystem ST50 server. If you're running a small workgroup server and need straightforward bulk capacity without the cost premium of SAS or SSD, this drive slots directly into the ST50's storage bays via a standard SATA interface — no adapter, no compatibility guesswork. At 1.90 lb and measuring 10.20 × 7.70 × 3.80 inches, it ships as a bare drive (no hot-swap tray included, as indicated by the NON-HS designation), so factor in whether your chassis configuration requires a compatible carrier.

Key Features

• 1TB Capacity: Sufficient bulk storage for operating system volumes, application data, and moderate file shares on a small server. For workloads that don't demand the density of multi-TB drives, 1TB keeps cost-per-bay in check without overprovisioning.
• 7200 RPM Spindle Speed: The 7200RPM rotation rate delivers meaningfully faster sequential read/write throughput versus 5400RPM nearline drives — relevant if this drive is serving an active OS volume or a frequently accessed data store rather than cold archive duty.
• SATA 6Gb/s Interface: The 6 Gbit/s SATA III interface is the current-generation standard for rotating hard drives, ensuring the drive doesn't become a bottleneck at the interface level. Compatible with any SATA III controller — no proprietary cabling or backplane required.
• 3.5-Inch Form Factor: Standard 3.5-inch drives are the baseline for tower and rack servers, offering higher areal density per dollar than 2.5-inch alternatives. Confirmed fit for the Lenovo ST50 chassis without modification.
• NON-HS (No Hot-Swap Tray): The drive ships without a hot-swap carrier or sled. In a non-redundant single-drive configuration or a build where you supply your own tray, this is a non-issue. If your ST50 is configured with hot-swap bays and you need a tray-ready assembly, verify whether you need to source a compatible carrier separately.
• Server/Workstation-Rated Component: Classified as a server and workstation storage component (UNSPSC 43201803), this drive is specified for continuous-duty environments — not a desktop drive repurposed for server use. That distinction matters for uptime in always-on deployments.
• Low System Weight Impact: At 1.90 lb, adding this drive has negligible effect on chassis weight balance — useful context when fully populating a tower server's drive bays.

Integration and Compatibility

The 4XB7A80527 is validated as a replacement component for the Lenovo server and storage line, specifically targeting the ST50 platform. The SATA 6Gb/s interface is backward-compatible with SATA II (3Gb/s) controllers, though throughput will be capped at the controller's rated speed. For environments running network-attached storage or small business file servers, a single 1TB drive like this is well-suited to OS-plus-data configurations where capacity requirements are moderate. If your deployment demands higher capacity per spindle or SAS-grade reliability tiers, consider stepping up within the server hard drive category to a higher-density option. For builds requiring redundancy, pair this drive with a matching unit in a RAID 1 mirror — the ST50 supports onboard RAID configurations that can protect against single-drive failure. If your storage architecture is growing toward video recording workloads or data-intensive applications, capacity planning at the drive level is worth doing before populating all bays.

Frequently Asked Questions

Q: What server is the Lenovo 4XB7A80527 designed for?

A: The 4XB7A80527 is specified as a replacement component for the Lenovo ThinkSystem ST50 server. It uses a standard SATA interface and 3.5-inch form factor compatible with that platform's storage bays.

Q: Does the 4XB7A80527 include a hot-swap tray or carrier?

A: No. The NON-HS designation in the product name indicates this drive ships as a bare drive without a hot-swap sled or carrier. If your ST50 is configured with hot-swap bays, you may need to source a compatible tray separately.

Q: What interface does the 4XB7A80527 use, and is it backward-compatible?

A: The drive uses a SATA 6Gb/s (SATA III) interface. It is backward-compatible with SATA II (3Gb/s) controllers, though maximum throughput will be limited to the controller's rated speed in that configuration.

Q: Is this drive suitable for 24/7 server operation?

A: The 4XB7A80527 is classified as a server and workstation storage component (UNSPSC 43201803), indicating it is specified for continuous-duty, always-on environments — as distinct from a consumer desktop drive.

Q: What is the spindle speed and how does it affect performance?

A: The drive spins at 7200 RPM, which provides better sequential throughput than 5400 RPM nearline drives. This makes it a better fit for active OS volumes or frequently accessed data stores than for pure cold-archive use cases.

James Everett

When I look at the 4XB7A80527, the detail that shapes the deployment decision most is the NON-HS designation combined with the 7200RPM spindle — this drive is built for active workloads in a fixed-bay configuration, not a hot-swap shelf you're pulling drives from under power. If you're provisioning an ST50 for a small branch office server handling file shares and light application data, this is a direct-fit replacement that won't require you to re-qualify anything.

Technical Highlights:

• SATA 6Gb/s Interface: Interfaces at the current-generation SATA III standard, meaning no interface-level bottleneck on a modern ST50 controller — throughput ceiling is the drive's mechanical performance, not the bus.
• 7200RPM Spindle: Faster rotation versus 5400RPM nearline alternatives translates to lower rotational latency and better sequential throughput — the right call for an OS volume or active application data store where seek times matter.
• 1.90 lb / 3.5-inch Form Factor: Standard tower-server sizing at a practical weight; no special mounting hardware needed beyond what ships with the ST50 chassis bays.

Deployment Considerations:

• The NON-HS designation means no carrier is included — if your ST50 bay configuration requires a tray, source the correct Lenovo-compatible sled before installing; a bare drive dropped into a hot-swap bay without a carrier won't seat or secure properly.
• At 1TB, this drive is appropriate for OS-plus-data on a lightly loaded server, but if your workload is growing toward multi-TB video retention or dense file storage, plan your capacity now — adding drives later is straightforward, but migrating a full OS volume mid-deployment is disruptive.

The 4XB7A80527 is the right specification for an ST50 running a small business file server, a workgroup application host, or a branch-office backup target where 1TB of reliable 7200RPM spinning storage covers the workload without overbuilding the budget.
