A:Answer I have the 7573 Special Edition, it came with a 512Gb M.2 SSD. I wanted, and still want more memory, I bought a 2.5 inch SSD thinking there would be room where the HHD is supposed to go. They have a bigger battery in this now so it takes up part of the room where the HHD should go. I am not a tech, but I suspect the only way to add a 2.5 inch SSD is to buy a smaller battery then you would have to buy a bus connector. I think the only way to increase the memory would be to replace the M.2 SSD that is in it. That would mean you would have to clone your boot info to the new SSD. On mine I did notice that the 16Gb RAM was one stick so to increase to 32Gb all you have to do in buy one more 16Gb stick. So that is kind of nice, I thought it would be 2-8's
If you know any different on the SSD I would appreciate knowing it too. ^_^
