They’ve played 36 times, more than any other two players around. Nadal holds the 21-15 edge, yet it isn’t that simple. He’s won five of their last six meetings after dropping seven straight to Djokovic. There’s a lot of physiology and psychology involved.

"The game's been changing year by year the last 10 years, and slowly they're weeding out the super-heavyweights and guys who are in the league just for that reason. The guys who are in the league now can play the game, skating and stuff. It's changing, slowly, it's slowly evaporating. It's sad to see, but it could happen down the road."

Hard drives with mechanical disks can’t move data as fast as customers want. Solid-state flash does not have the encumbrance of all those moving parts, which enables data to move at a scale far faster than with hard disks.
