Yeah I know, but I'm saying it won't take long to develop those hardware, because big companies are also searching for this, google and facebook have loads of petabytes of data going into their system everyday. What do you think they prefer? installing lots of drives, or installing a big one everyday?
I hope they continue developing as fast as possible

I actually happen to know Google prefers multiple drives. You can keep better backups, and one disk failing doesn't break the system entirely, or even close to significantly.
