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

[This SD Card has a read/write speed of 160/90 mb/s](https://www.amazon.com/SanDisk-Extreme-microSDXC-Memory-Adapter/dp/B07P9W5HJV)

The absolute cheapest SSDs you can find on the market have a read/write of 1000 mb/s, with most gaming SSDs boasting 5000 or even 7000 mb/s

They’re dreadfully slow and really only useful for low end systems like the Switch or Steam Deck
