LeBron James, meanwhile, had 23 points, seven rebounds and eight assists in 41 minutes as his incredible playoff run came to a quiet end.
Unfortunately, Hood was the only reserve to make a real dent in Game 3.
Golden State claimed the sixth crown in club history, matching the Chicago Bulls for third on the all-time list.
"This was the hardest one we've had by far", Warriors coach Steve Kerr said.
Overcoming obstacles all season long, the Warriors were not going to be denied and won the fourth straight finals matchup against Cleveland easily.
"We used the experience past year to our advantage", Curry said.
Durant did in the Cavaliers in similar fashion in Game 3 one season ago and he was even more deadly this time around. He played through blurry vision, a twisted ankle and a busted hand suffered in the aftermath of Game 1, a self-inflicted injury that wasn't revealed until the series was over.
"For me, tonight will be tough", James said. That boiled over on May 13, 2010, when James ripped his jersey off after a series-clinching loss to Boston in the conference semifinals. James still shot 49% from the field over the last three games, but just 27% on three-point attempts with fewer than four attempts per game.

Non-US G7 members say they will be firm as they confront Mr Trump but do not want a rupture that could cause a major trade war. President Donald Trump told reporters on Friday that he thought Russian Federation should be reinstated as a member of the G8.
"We had more talent than they did, and talent wins in this league", Kerr said. "Getting up every day, going to work with these guys, it's incredible".
Think the Trail Blazers still regret drafting Greg Oden No. 1 in the 2007 draft instead of Durant, who went No. 2? Then, in the last minute, game Durant's big shot, and the Cavs just didn't have enough gas in their tank to stop the Warriors. The new guys who had a chance to play in the playoffs for the first time, the new guys who had a chance to experience The Finals, which you dream of doing when you're a kid.
"It's a journey that's better than the destination". With his 43-point performance in Game 3, Durant joined Jordan and Shaquille O'Neal as the only players to score at least 25 points in their first 13 finals games.
Seems like a reasonable bet that James, long thought to be the real GM in Cleveland, didn't sign off on that particular trade.
Golden boys: Kevin Durant, second from left, celebrates after the Warriors defeated the Cavaliers.
Lue removed James with 4:03 to go, replacing him with rookie Cedi Osman.
"When you play one of the best it brings the best out of you as well", Durant said of playing against James.
James had two MRIs during the series and wore a soft cast when he wasn't practicing or playing or in view of the media, sources said, so as not to give the Warriors a competitive advantage.
