Why are there 1TB micro SD cards that are the size fingernail and most 1TB hard drives are bigger than my hand?
In: Technology
It’s not about getting data as dense as possible. It’s about cost. Hard drives are much cheaper than solid state storage per unit of storage. The best deals are around $15 per TB while a 1 TB microsd card is several hundred dollars.
You can get those massive densities with a hard drive like physical size. There are solid state drives that are tens of terabytes but they cost thousands to tens of thousands of dollars each.
