I mena I was nder impression that extending SSD size is easy and cheap in more then 1 way:
You can get SD Card up to 256 GB
You can put an USB stick & since EVE V has so many USB porst you wouldn’t even notice that 1 is missing. An they crete these hings now so that they don’t stick to much so it can be there permanently.
You can get external SSD and connect it over USB.
You can get cloud storage (slowest option)
And I think that all of these aproaches are much cheaper then going from M3 to i5.
All are great options if you need more space for images, video, music and so on.
But I am not sure if it is OK to install a game on SD Card and then run it from there.
I would assume loading times might be slower but once the game is loaded into memory you shouldn’t notice much difference.
In conclusion I would say that extending SSD as statted above should be OK for most users and most scenarios for which Eve V is designed.
