Samsung’s adorably tiny portable SSDs leave flash drives and external hard drives in the dust, and the 500GB and 250GB models are cheaper than ever today. It’s still a lot more expensive than a portable hard drive, but in addition to the speed and size advantages, it should be more durable as well, due to a lack of moving parts.
