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.
It’s just a form factor. Computer cases have 2.5 and 3.5 inch form factors for hard drives, and they are made to fit that size. If you look at a NVMe drive, it looks like a tiny stick of memory, yet that can be a couple of terabytes as well. Once again, even that is a set form factor size.
They getting smaller though – an 1TB m.2 nvme drive can get 5,000 MB/s and it’s a stick of Ram size wise basically
As cards are unreliable as fuck. I have yet to have one that didn’t fail and delete all of my data. They are definitely not meant for continual usage
Drives are standardized so they will work in any computer, the size doesn’t have much to do with the capacity. The size and mounting has been the same for a long time, from when 80gb was a pretty big drive and now there’s 10+tb drives that are exactly the same size.
