SSD Failure Testing - An Automated Testing Solution
Details
This post recaps a project I worked on while at Plus One Robotics.
We had some SSD failures and wanted to get to the root cause, so one test conducted involved testing the effects of sudden power cutoffs.
System Overview
I was really into state charts at the time since we were doing some related documentation for other projects. It's really helpful to be able to visualize dataflow and gives you a sens of direction when you get lost in the software sauce.
Here's the one I designed for this system:
To test I designed a Rust based power toggling system of the Rasberry Pi 3 (image below).
At the time we were doing separate documentation in Autocad Electrical which I found to be unintuitive and painful to work with. So I made the above design in Kicad.
The SSDs were placed in an IPC running Ubuntu with a service that did file system corruption testing on a mock file directory.
