Currently been looking at Samsung Evo because quality and they are the top contenders for speed in IOPS and 4k read / write but kinda expensive for 500gb been trying to get one for max of 140$
Whether a gamer or not, you should always buy the largest capacity you can afford, especially if it's an SSD as they are still relatively poor value for money per MB compared to HDDs.
i was thinking of going with a hdd black and as for the sandisk ultra i was gonna get samsung one from jet.com but they have no warranties that i can find other then a return policy which doesn't help if it breaks down in 5 months or later
