Installing an NVMe SSD
The RV2 features an M.2 Key-B socket that provides the flexibility to install either an NVMe SSD for enhanced storage or a 4G/5G modem card for fast internet connectivity. In our setup, we selected a KingSpec PCIe Gen 3×2 NVMe SSD with a generous 1TB capacity, which was successfully identified by the Immortal OpenWRT snapshot we tested on this device. If you aim to enhance the cooling of the card, consider adding a large heatsink, however, it’s important to note that this is not essential.
