The talk will present a quantitative comparison of digital/electronic and biological storage systems. Two biological storage systems will be included: DNA and brain memory. First we will show some opinions on brain-computer relationship from the past (including views of Turing, von Neumann, Schrödinger). In the main part of the talk, we will discuss different storage aspects, mostly quantitative, such as: organization, functionality, data density, capacity, power consumption, redundancy, integrity, access time and data transfer rate. Numerous analogies between biological and electronic storage systems will be pointed out. Finally, we will try to answer some general questions: Are there any common features of diverse storage systems? Does computer storage match brain capabilities? Is there a joint future of diverse storage systems?
