Lenovo 4XB7A80542 ST50 3.5 S4500 960GB Nonhs SATA SSD V2

Lenovo 4XB7A80542 ST50 3.5" S4500 960GB Non-Hot-Swap SATA SSD V2

The Lenovo 4XB7A80542 is a 960GB S4500-series 3.5-inch SATA solid-state drive qualified for the Lenovo ThinkSystem ST50 server platform. Sourced as a factory-new, genuine Lenovo option part, it installs into the ST50's non-hot-swap drive bay and connects via the server's onboard SATA interface — no additional HBA or cabling adapter required for supported configurations. For integrators building entry-level server infrastructure or expanding storage in an existing ST50, this drive is the correct Lenovo-qualified path rather than a third-party substitute that may trigger firmware compatibility warnings.

Key Features

• 960GB SATA SSD Capacity: Provides solid-state storage density suitable for OS volumes, application data, or lightweight workloads on the ST50 — SSD means no moving parts and lower acoustic output versus spinning disk, relevant in office-adjacent or light industrial deployments.
• S4500 Enterprise Drive Series: The S4500 designation places this in Lenovo's mainstream enterprise SSD tier, matched to steady mixed-read/write workloads rather than write-intensive database roles — appropriate for general server storage rather than high-endurance applications.
• 3.5-Inch Non-Hot-Swap Form Factor: Designed for the ST50's fixed drive bays. Non-hot-swap means the server must be powered down for installation or removal — plan maintenance windows accordingly. The 3.5-inch chassis fit ensures correct seating without adapters in the ST50's native bay.
• SATA Interface: Connects directly to the ST50 motherboard's native SATA ports. No PCIe slot consumption, no NVMe driver dependency — straightforward deployment for standard server OS installations.
• Genuine Lenovo Option Part: Sourced as a factory-new Lenovo-qualified component. Using a Lenovo option part avoids compatibility flags in the ST50's UEFI/XClarity tooling that can appear with non-validated third-party drives.

Compatibility Note

The 4XB7A80542 is validated for the ThinkSystem ST50 server family. Before ordering, confirm your ST50 generation and current drive bay population against Lenovo's ServerProven compatibility list for this part number. SATA port availability and backplane configuration vary by ST50 build — verify open non-hot-swap bays in your specific chassis.

Frequently Asked Questions

Q: Is the 4XB7A80542 a hot-swap drive?

A: No. The 4XB7A80542 is a non-hot-swap drive. The server must be powered down before installing or removing this drive.

Q: What server platform is the 4XB7A80542 validated for?

A: This drive is qualified for the Lenovo ThinkSystem ST50 server. Verify compatibility with your specific ST50 generation via Lenovo's ServerProven tool before installation.

Q: What interface does the 4XB7A80542 use?

A: SATA. It connects to the ST50's onboard SATA ports — no additional controller card is required in a standard ST50 configuration.

Q: Is this a new drive or a refurbished unit?

A: The 4XB7A80542 is sourced as a factory-new, genuine Lenovo option part — not refurbished or grey-market.

James Everett

The 4XB7A80542 fills a specific gap: when you need to expand storage in a ThinkSystem ST50 without sourcing an unvalidated third-party drive and risking UEFI compatibility warnings during POST. The SATA interface and 3.5-inch non-hot-swap form factor are straightforward — this is not a complex deployment, but it is a qualified one.

Technical Highlights:

• 960GB Capacity via SATA: Adequate for OS-plus-application volumes on an entry server; SATA avoids any NVMe driver or PCIe slot dependency in the ST50 platform.
• S4500 Enterprise Tier: Positioned for mixed steady-state workloads — not write-intensive, not the right pick for a high-transaction database role, but correct for general server storage in the ST50's target use case.
• Non-Hot-Swap Design: The 3.5-inch fixed-bay form factor means zero complexity in bay fit, but plan a maintenance window — you cannot swap this under power.

Deployment Considerations:

• Confirm open non-hot-swap 3.5-inch bays in your specific ST50 chassis before ordering — bay count and backplane type vary by ST50 configuration and existing drive population.
• Evidence for this SKU is limited to distribution feed attributes; validate read/write endurance specs against Lenovo's published S4500 datasheet if your workload is write-heavy before committing to this drive tier.

The right fit for an ST50 running a small-site file server, lightweight virtualization host, or surveillance NVR OS volume — where Lenovo platform validation matters more than raw performance headroom.
