I'm looking to buy an external ssd for my pc (~$30). There's 2 that caught my attention: Kioxia Exceria 480gb and a used 850evo 500gb (other samsung sata ssds are no longer available). I'm just using it to store random stuff and maybe install some games on it. The Kioxia doesn't seem to have DRAM and I'm not sure if that's bad for the ssd's longevity. Which one should I get?
