I've actually already got two Espruino boards in my loft that I use for tests/benchmarking. In this case the SD code actually worked, for reading directories, and reading/writing files. AFAIK it was just appending them that was a problem - so hardly surprising it didn't pass the test.
Benchmark code is here
Perhaps we could come up with some simple design that we could share - like one board on top of the other, or perhaps even just one board with certain IO lines shorted. You just need to connect up Reset/BOOT0 pins so that one device can be reliably be put into bootloader mode.
Then, we could all come up with a whole bunch of different tests to run.
PS. the build with it fixes is here
