Hello everyone, I might need some help on upgrading the Razer Blade 15 SSD that I bought, didn't get it yet, and it's the first laptop I ever purchased. I wonder did the Blade 15 comes with just one SSD installed? I saw the specs on the page said it has 4 slot for upgrades the SSD, so can I just open the back of the Blade, and then install the SSD 980 NVMe M.2(the one I can afford) in the empty slot after I received the laptop(before turn it on)? Or I still have to do the Windows recovery things(what I know on the research)? Help please.
