microSD card performance comparison

Then they end up with a fake card with less capacity/performance/reliability but it's hard to convince them that they bought crap. That's the reason why we added to our user documentation two links how to check for bad cards, two links how to choose a better one (already containing your link from above) and in the meantime an own utility to check SD cards even if they're already in use.

Seriously though, if you don't want to use it, don't use it!

I don't know why everyone is going on about fake SD cards.  Do you think my cards are fake?  I purchased the cards at Amazon and would expect any reputable dealer to not be selling fake cards.

On your other points, not everyone is using armbian or has access to that tool to check for bad cards.  I tried installing your tool, but it's not trivial on arch linux with aarch64 (especially for a novice like myself).

However, this spreadsheet isn't really meant as a test for bad cards.  This is meant to benchmark a variety of cards to help people select a card for best performance.  And I also have no problem with adding performance numbers from armbianmonitor.

The SD cards I tested are not in the table of benchmarked cards linked above.  We also might expect performance to be slightly different from the Raspberry Pi 2, which is what was used in the benchmark I linked.  

I think all these reasons taken together justify creating a new table of benchmarked cards.  But, as I said, if you don't want to use it, no one is forcing you to.
