Redis is persistent, replicated storage, isn't it? No matter what buzzwords they use on their site, Memcached is a volatile cache, it should never be used to store otherwise irretrievable information. I know, people use it for stuff like session storage, but that's really not a good use case for it. I don't want to attack Redis, so there is no need to defend it. Maybe memcached-like behavior is one of its many features, but I personally like Memcached exactly because of its simplicity.
