@jdrumsr According to the XPS 8930 Setup and Specifications the limit for PCIe/NVMe SSD is up to 1TB, but according to this post that may be an error, and that Dell actually sells the XPS 8930 with a 2TB M.2 PCIe NVMe SSD.

Hi, @Vic384 ,

Maybe the apparent disparity is simply down to the fact that Dell usually do NOT update their Documentation following initial Launch of a Product Range.

Hence the Specifications Document would ONLY include the Information that had been Validated at the time of initial Release - however, it is always possible that Dell have subsequently Validated other options/specs??
