Why do we still use hard drives and SSDs for computers, when SD cards can hold like a TB of data in a tiny package?

Question

I’m kinda curious as to why everything hasn’t just shifted over to these tiny, affordable little guys. They can have so much on them!

Answer 1

Imagine you had a book that had 1000s of pages. You can read 250 words a minute but your friend can read 10,000 words a minute. You would definitely say your friend is a better reader even if the book he is reading from has bigger pages. SSDs just have much better performance and longevity.
