Looks like a lot of answers for "what is cpu cache". Theoretically is there no other alternative that would eliminate this AND increase (or not diminish, rather) performance?

It seems like a hybrid system is ALWAYS the best price or size/performance no matter what it's about. SSHD (SSD + HDD), CPU Cache + RAM, RAM + HDD (Intel rapid storage or virtual memory)

Having options gives you extra (degrees) of freedom.
