With the introduction of PCIe connections on the Raspberry Pi 5, we are seeing the launch of new products that use this interface for fast NVMe storage. I previously documented my Home Assistant migration from SD-card to SSD on my Raspberry Pi 4 using an Argon ONE M.2 SSD case.| Martin Rowan
PCIe connected NVMe storage is available with the Pimoroni NVMe base for Raspberry Pi5. Faster than USB connected NVMe, but still some compatibility issues.| Martin Rowan
The Argon ONE NVMe expansion board should provide high speed storage to your Raspberry Pi 4, however its performance is lower than expected| Martin Rowan
