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

Read/write speed, mostly.

There’s a better alternative called M.2 (NVMe SSD) which is similar to an SD card in function, but can read/write data muuuuuuuuuch faster than SD cards. like up to 15 times faster, theoretically, but still at least 5-10x in practice right now.
