You would buy an SD card with static and dynamic wear leveling.

A quick format is good enough. It writes and puts a FAT or $MFT on the partition.

The slow format does the same, except it includes a read-verify of the surface.

To "erase" a storage device, diskpart "clean all" will write the entire
surface with zeros. Or dd.exe can write the surface with zeros.

It's hard to get good info about SD, like the wear leveling scheme.
If it has both static and dynamic wear leveling, it could last longer
because then you can't really burn a hole in it as easily.

The difference to a USB flash stick, could be the binning of the flash.
Maybe the flash is a bit better. USB sticks could be pretty low quality.
Like purchasing a 16GB USB key, could be a 32GB chip with half of it
pinned off because it didn't pass.

SD has limits on both write speed and read speed. The physical interface
is pretty "thin", and that's why it can't read faster than it does.
There is a promise that coming SD cards will have one lane PCI Express
interfaces, which should make then read better. But when that is done,
the writing won't be faster. Just as the worse USB3 flash sticks might be
100MB/sec read and 10MB/sec write. My Rally2 can write at about 16MB/sec,
but it doesn't read in a big hurry. Whereas USB3 sticks can have larger
differences between read and write. And some USB, have "uneven" behavior.
I've got a stick here now, it stalls for a while, it does a tiny bit of
writes, then stalls some more. My SD doesn't do that.
