If you want to know more about how to calculate a good redo log size, check out this blog post: MySQL 8.0 The answer does not consider the queue or latency of the sample, which could indicate a disk with issues. Also, the redo log capacity is not the same as the redo log buffer, so it mixes different technologies and concepts.
