Hey there, I am about to buy a new laptop for a college program, going back to school. The laptop I want is a Dell XPS 15. The program is saying I need a 1TB hd. If I get a laptop with a small SSD and a large HD, it will take up battery room, which I don't want. My question is, Is a 1TB SSD safe and reliable? I've heard and read mixed things about large ssd's. I am ok spending the money on a big SSD if it means I dont have to use an external HD. Thanks!
