3. Memory and storage

For better or for worse, the memory of this device is soldered to the motherboard. The maximum supported capacity is 16GB of LPDDR5 RAM, working at 4800MHz. Storage-wise, you get one M.2 PCIe x4 slot with support of Gen 4 SSDs. To access it, you need to remove its metal bracket by undoing two Phillips-head screws.
