Features: The X1005 NVMe Double Solid Disk Adapter Board is to provide a seamlessly, fast speed storage solution for RPi 5. Easy to connect two different lengths of M.2 Solid Disks (including the 2280, 2260, 2242 and 2230) to your RPi 5. With its PCIe 2.0 interfaces, you can experience data transfer rates of up to 5Gbps, allowing you to easily transfer large amounts of data very fast. The X1005 is mounted on the back of the RPi 5 and not require GPIO passthrough. This means you can use your favourite adapter and still take advantage of the NVMe expansion board. In addition, it integrates perfectly with the official for RPi passive cooling and not interfere with heat dissipation. Mounting holes and brackets provide additional protections for your solid disc drive while effectively dissipating heat.
