Expansion board Argon40 Argon One M.2 NVMe for Raspberry Pi 4B — M.2 NVMe SSD support

The Argon40 Argon One M.2 NVMe expansion board for Raspberry Pi 4B provides a compact interface to add an M.2 NVMe SSD to a Raspberry Pi 4B system. Designed to integrate with Argon One enclosures or compatible setups, the board enables higher sequential read and write performance compared with microSD storage and supports use as primary system storage or additional data storage for projects that require faster I/O.

Advantages

This expansion board delivers NVMe SSD support via a dedicated M.2 slot, enabling faster boot times, improved application responsiveness and higher sustained data transfer rates compared to microSD cards. Its design is compatible with Argon One cases and similar mounting arrangements, allowing neat installation and efficient use of the Raspberry Pi 4B form factor. The board reduces reliance on lower-performance removable media and helps extend the Raspberry Pi’s usability for server, media and database tasks.

Suitable for

• Using an NVMe SSD as the primary boot drive for Raspberry Pi 4B
• File servers, NAS or network storage appliances based on Raspberry Pi
• Media center builds requiring reliable, high-throughput storage
• Single-board computer projects needing faster random and sequential I/O

Key specifications

• M.2 slot supporting NVMe SSDs (form factor compatibility dependent on board design)
• Compact board dimensions suitable for Argon One chassis integration
• Power and data routing optimized for single-board computer operation

How to use

Install an M.2 NVMe SSD of a compatible form factor into the board’s M.2 slot and secure it according to the board’s mounting points. Mount the expansion board inside an Argon One enclosure or a compatible case, connect it to the Raspberry Pi 4B’s NVMe-capable interface, and apply power. Configure the Raspberry Pi firmware and operating system to recognize and boot from NVMe if intended as the primary system drive; otherwise format and mount the drive for data storage. Follow standard precautions for handling SSDs and working inside compact enclosures.

Usage recommendations

Use a high-quality NVMe SSD from a reputable manufacturer, ensure adequate thermal management when operating under sustained load, and update Raspberry Pi firmware to the latest version for best compatibility when booting from NVMe storage.
