Cisco SSD-240G — 240GB USB 3.0 Solid-State Drive for Catalyst Switches
What it is
SSD-240G is a Cisco 240GB USB 3.0 solid-state drive designed to provide local storage for compatible Cisco Catalyst switches.
It can be used for application hosting, packet captures, logs, trace files, and other local storage needs, giving the switch significantly more onboard storage than its standard internal flash.
Why buyers pick SSD-240G (plain English)
Adds 240GB of local storage: Gives supported Catalyst switches a large amount of additional storage for applications, diagnostic data, and operational files.
Built for application hosting: The 240GB model is particularly useful when running applications or containers directly on the switch.
USB 3.0 connectivity: Installs directly into the switch's supported USB 3.0 SSD interface without requiring a separate external enclosure.
Field replaceable: Designed as a FRU (Field Replaceable Unit), so it can be removed or replaced onsite.
Useful for troubleshooting: Provides space for packet captures, trace logs, crash information, and other diagnostic files without consuming the switch's main flash storage.

Where it fits (and when to choose something else)
Perfect for:
- Catalyst switches running local applications
- Cisco IOx deployments
- Storing large packet captures
- Keeping diagnostic and trace files locally
- Edge-computing applications
- Customers needing more storage than standard switch flash provides
Choose something else if:
- You need less capacity → consider SSD-120G
- Your switch requires the newer C9K-F1-SSD storage format → use the appropriate Catalyst 9000 SSD
- You need 480GB or 960GB → choose a higher-capacity supported Cisco SSD
- You only need to transfer IOS XE images occasionally → a standard supported USB flash device may be sufficient
- Your switch does not have a compatible USB 3.0 SSD interface → verify platform compatibility before ordering
TL;DR
SSD-240G is a Cisco 240GB USB 3.0 solid-state drive designed for compatible Catalyst switches, providing additional local storage for application hosting, packet captures, logs, diagnostics, and edge applications.
