I was getting frustrating at using the ''wrong'' MicroSD cards in write-intensive operations like a Raspberry Pi, so I set out to test the assortment of 32GB and 64GB MicroSD cards I have.

====== Testing setup: ======

* SABRENT USB 3.1 MicroSD reader
* Dedicated (not-shared) USB 3.1 port on my desktop PC
* f3read / f3write from the [https://fight-flash-fraud.readthedocs.io/en/latest/introduction.html Fight Flash Fraud] project.

Results from the assortment of MicroSD cards I have are in the table below. All tests were done on blank cards, on an idle machine.

Speeds are in MB/s, and the average speed after writing/reading at least 5GB.
