I don't see any problem, theoretically you could install a 4TB SSD. BUT: We have not designed the hardware, a small residual risk remains, e.g. that the installed controller chipset can only address 1000G or 1TB. (for whatever reason)

As far as I know, it does not matter how large the memory of the ssd is. Many manufacturers recommend how much each person needs for the product to run optimally.
