Detailed description：I want to upgrade the storage of my asus x509ua-ht731t. Originally it only has 1Tb HDD but I want to add M.2 Nvme SSD to make it a double storage. I just want to ask for help if it really has slot for M.2 SSD? Cause based on my research, X509 models has M.2 slot but just to make it sure. Thank you in advance.
