How long would it take the super-ist super-computer to generate & save 1/10 of all possible addresses? .0686 btc bounty!

My short answer would be that if hard drives could each hold a million terabytes, it would still take a batch of hard drives greater than the weight of the entire earth to save all of those addresses.

According to my back of the envelope calculation, that would be 304479.5 earth masses (~ 1 solar mass). (Assuming 1 exabyte per 500 gr. hard drive, each address is 25 bytes.)
