Are these benchmark numbers normal?

. I just can't seem to find out why the 4K reads are slow.

Your drive is unusually fast because of RAPID. Other than that the 4K low queue depth looks fine to me.

Maybe I'm not understanding something here but I would assume that reading would almost always be way faster than writing since well... you're not changing anything, you're just reading data.

No. Writing is faster because of RAPID. You are not actually writing to the SSD but the software cache. Writes are delayed and combined before they go to the SSD so you get a higher #s for that. Even without the cache writes are sometimes faster because of caching on the SSD itself.
