Write cache vs. write cache with deferred writes?

Is the difference between having an L2 write cache and a L2 write cache with deferred writes at all similar to a write through vs. write back cache?
What are the risks associated with having primocache setup with an L2 write cache as opposed to just a plain L2 read cache?

SSD write cycles are limited. Use L2 to cache write-data will greatly increase write wear on the L2 device. So by default, L2 is set to cache read-data only.
