Depending on which 256K you lose, you might as well lose your entire database.
Let's be nice and assume that you only lose one 8K block because of the SSD write cache; that's not so bad, right? Guess what--you could easily be the next lucky person who discovers the block corrupted is actually in the middle of the pg_class system catalog, where the list of tables in the database is at! Enjoy getting your data back again with that piece missing. It's really a fun time, I'll tell you that.
