I am looking for a good PS4 Pro external SSD (at least 500gb). I am unfortunately on a budget and would prefer $110 or less, preferably less. What is the difference between the Adata SD600 and SD700? I saw both for 512gb, the sd600 for $88 and the sd700 for $105. Are there any comparable external SSDs for PS4 Pro that I can get for less than $110?
