Lenovo 4XB7A80539 ST50 3.5 S4500 240GB Nonhs SATA SSD V2

Lenovo 4XB7A80539 240GB SATA SSD for ThinkSystem ST50

Overview

The Lenovo 4XB7A80539 is a 240GB S4500 SATA solid-state drive in a 3.5-inch non-hot-swap form factor, configured for the ThinkSystem ST50 server platform. If you are provisioning an ST50 for a light-workload role — a DNS/DHCP node, a small branch file server, a VMS appliance in a single-camera deployment, or a dedicated domain controller — this drive slots directly into the ST50's fixed storage bay without requiring a hot-swap backplane or additional carriers.

The SATA interface keeps compatibility straightforward: the ST50 does not carry a SAS backplane, so SATA is the correct interface family for this platform. The 240GB capacity is adequate for an OS volume with room for application binaries and local logs, but is not sized for bulk video retention or large database workloads — plan accordingly when specifying storage architecture.

Key Features

• 240GB S4500-Class SSD: solid-state media means no moving parts and measurably lower vibration sensitivity compared to spinning disks — useful in environments where multiple drives are co-located in a small chassis and rotational vibration coupling is a concern.
• 3.5-Inch Non-Hot-Swap Form Factor: the non-hot-swap designation means drive replacement requires a planned maintenance window with the server powered down. Factor this into your SLA before specifying for uptime-sensitive roles.
• SATA Interface: native to the ST50 platform; no HBA, no SAS expander, no cabling adapters required — simplifies installation and keeps the BOM clean.
• ST50 Platform Fit: Lenovo validates drive compatibility at the platform level; using a platform-matched part avoids firmware-level compatibility issues that can surface with generic aftermarket drives in server-class systems.

Integration and Compatibility

The 4XB7A80539 is designed for the ThinkSystem ST50, Lenovo's entry-level tower server. Confirm your ST50's generation and bay configuration against Lenovo's current compatibility matrix before ordering — ST50 V2 and original ST50 may differ in supported drive lists. This drive is not interchangeable with SAS backplane systems or hot-swap configurations without the appropriate carrier bracket.

Frequently Asked Questions

Q: Is the 4XB7A80539 a hot-swap drive?

A: No. The 4XB7A80539 is a non-hot-swap (Nonhs) drive. The server must be powered down before installing or replacing this drive.

Q: What server platform is this drive designed for?

A: This drive is configured for the Lenovo ThinkSystem ST50 server platform.

Q: What interface does the 4XB7A80539 use?

A: SATA. It is not a SAS drive and will not fit a SAS-only backplane without an adapter.

Q: Is 240GB sufficient for a VMS operating system volume?

A: For OS and application use, 240GB is generally adequate. It is not sized for local video retention — a dedicated, higher-capacity storage volume or NAS/NVR should handle recording storage separately.

Q: Can this drive be used in other Lenovo server platforms besides the ST50?

A: Lenovo qualifies drives at the platform level. Cross-platform compatibility should be verified against Lenovo's official compatibility matrix for each target system before ordering.

Karl Wilson

The 4XB7A80539 is a platform-specific part — Lenovo's S4500-class 240GB SATA SSD in a 3.5-inch non-hot-swap form factor, validated for the ThinkSystem ST50. I specify this drive when a customer needs a clean, no-surprises OS volume in an ST50 and wants to stay within Lenovo's qualified parts list rather than introduce a generic aftermarket drive into a server that will run unattended.

Technical Highlights:

• Non-Hot-Swap Designation: the Nonhs rating is a hard operational constraint — any maintenance window that involves this drive requires a full server shutdown. If your SLA cannot tolerate that, the ST50 platform itself may need re-evaluation, not just the drive.
• 240GB SATA SSD: correctly sized for an OS/application volume; not a data storage drive. Customers who expect to store video recordings or large datasets locally on this drive will run out of space quickly and should plan a separate storage tier.
• Platform Qualification: Lenovo validates drives at the system level. Using the 4XB7A80539 as the ST50-qualified part eliminates the risk of firmware-level incompatibilities that occasionally surface when generic SATA SSDs are installed in server platforms with active storage controller management.

Deployment Considerations:

• Confirm ST50 generation before ordering — the V2 revision has an updated compatibility list and the validated drive set may differ from the original ST50.
• The evidence does not document DWPD, MTBF, or read/write throughput for this SKU from the available source; verify those figures against Lenovo's current datasheet if endurance rating matters for your workload.

Best fit: a ThinkSystem ST50 deployed as a lightweight VMS appliance, branch domain controller, or small office file server where the OS volume needs to be a Lenovo-qualified part and planned maintenance windows are acceptable.
