Sorry I can't provide links. But I work for a large tech company, currently qualifying SSDs for a new project. We ran into serious bugs with drives from a particular well-known SSD manufacturer (certain workloads cause drives to become unresponsive until power is cycled) and were able to demand detailed root cause analysis. In at least two cases they uncovered new bugs in code that had been inserted purely to improve the numbers for 4k random writes on certain benchmarks. These are consumer drives, not enterprise, and are current production.
