This UCG-Fiber (30W) Cloud Gateway Fibre device is also available with a pre-installed NVME SSD with a capacity of 1TB (UCG-Fiber-1TB (30W)) and 2TB (UCG-Fiber-1TB (30W)). With the matching M.2 SSD sled UACC SSD tray, you can retrofit a suitable NVMW SSD yourself. Unfortunately, I cannot find this article (M.2 SSD tray, UACC SSD tray) in the shop. Please add it to the shop and mention this fact in the article & specification description.
