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 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.
