I am not sure, but after looking at their sites they probably mean images. So, a synapse in a let's say high resolution jpeg will need much more memory than my abstract definition of a synapse.

i'm wondering if the massive amounts of Petabytes can be compressed in some efficient way. probably.

Well, of course. I would suggest paq8l ;)

I think you can store very efficiently. A neuron or synapse has a huge error rate. So, saving parameters of the synapse as 4 byte floating point number could be overkill. Connection information could be also reduced significantly by an intelligent sorting. E. g. you don't have to store the source index and neurons connect probably more to their neighbors then to neurons far away. Therefore I am wondering, what must be saved in 24 byte. Well, we will know, when we try it some day. At the moment it's just speculation.
