Speed testing cheap Banggood Micro SD Cards

At the makerspace we always seem to have a shortage of Micro SD cards for Raspberry Pi’s so I decided to buy some cheap ones from Banggood and test them in the hope that I stumble across one that isn’t terrible speed-wise.

For testing I used Blackmagicdesign Disk Speed Test.

Here’s the results for my 3 recent purchases:
