I am still in high school but my curiosity is not stopping me from posting in this forum.
How is data stored in SSD? How does it differ from the old HDD? I heard that atoms are used to store data. How?
Binary consists of 0 and 1. How does someone use an atom to represent 0 and 1?
Does positive ions represent 1 and negative ions represent 0?

As with all questions of this sort, you will get better answers if you first do your own research, then ask us for help with the specific parts that weren't clear to you. If you google for "solid state drive" you will get a bunch of hits including a wikipedia page. Read that, then come back with more specific questions.
