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!

Same question could be asked about SSDs—why do we use SSDs when HDDs hold more information for a fraction of the cost?
Not everything is about storage and size. SSDs are much faster than HDDs, but more expensive. Same w SD cards—they can have more space, sure, but they’re a lot slower than HDDs and SSDs. Additionally, SD cards have worse longevity than HDDs/SSDs, meaning that they’ll start to break down after fewer reads/writes than other drives.
With anything, there’s tradeoffs. Storage media is always a tradeoff between speed, cost, and capacity. SD cards are slow, cheap, and big. SSDs are fast, expensive, and small. HDDs are medium speed, cheap, and big. Servers use HDDs because you can get a lot of reliable storage for the price at minimal cost. Modern home computers use SSDs because they’re fast and the cost isn’t a super big deal since you don’t need massive amounts of storage. SD cards are used for cameras and other similar storage because they’re cheap, large, and have a small footprint, and the speed/reliability is a low concern (since you’re just going to transfer them to a computer quickly anyway).
