Raspberry Pi tools
If I make more tools then I will add them here, but currently this is just one tool called rpi-sdinfo.
A script to (a) test the performance and integrity of SD cards, (b) try and spot genuine/fake SD cards. I wrote the original in bash but then I started to re-write it in python. Neither are completely finished for a v1.0 but its a solid start. If it was useful then I would probably build a public web service where everyone could share their results to build up a database of SD card identifiers, performance, and failure rates.
