I'm planning to buy a bigger SSD but soon a question came up to my mind: would my performance fall down after moving the OS on the bigger SSD (like it happens from HDD > SSD without clean install)? In my opinion the answer is 'no' because we're talking about the same type of device, but I wanted to know what do you think about it
EDIT My question is slightly different. My concern is that migrating the OS on a new SSD might affect performances, but sure the new one is better than mine (it's a 850 EVO 500GB vs 840 EVO 120GB)
