My SSD is probably pretty fast, but maybe a faster one would let me compile a kernel even quicker by reducing the time spent waiting for I/O to complete. First though, I need to determine its latency, and the benchmark tool available to me, dd, measures throughput not latency. We need to go deeper.

I wrote some rust code. I used unsafe. It was unsafe. After months of contemplating this unfortunate result, I’ve found someone else to blame.
