I no longer have card slots built into my computer or connected to a printer, but a USB adapter replaces most of that hardware. And it's not limited to a few gigabytes like it used to be. I've used it to transfer from my phone's 64GB external card and it's much faster than a regular wired USB connection. I haven't used it from a phone to external storage, but note that it fits Samsung exactly as it leaves the microSD side against the port's flip cover.
