A LRU write will be destaged to disk.
A WP Write will only be to cache, there is no disk operation for this type of write.
Also the LRU write requires the FA to allocate a cache slot and make it WP, the WP write does not.

What about these terms referring to an SRDF director?

I would assume the same. LRU will be destaged to disk, WP write will only go to cache.
