Ssd buying guide

Hii guys so i recently just got my new loq 15ahp10 and i want to buy another ssd so that i can download some games to play. Any recommendation or tips buying a new ssd?
My budget is around rm500\~800 for 1tb storage
Just to add on, i am new to these stuffs and i watched many videos about ssd and i am not sure about the dram and stuffs like that
