There is no such thing as "raid caching". There is something

I'm not trying to start a debate, but I don't follow this logic
What if the system tries to read back some write cached data?
If it delays the commit then it delays readback, unless it
allows read from the cache, in which case it speeds up reads.
Either way it greatly affects reads.
