Storm have made it seven in a row in fine style, recording their biggest win of the season with a 46-0 triumph over the Roosters.
The 46-point deficit was also Melbourne's biggest ever win over Sydney and the first time they had kept the Bondi-based club scoreless.
Suliasi Vunivalu continued his breathtaking start to life in the NRL, scoring a hat-trick to make it 11 tries in seven career games.
Cooper Cronk also added a double but it was Cameron Munster who put on an 80-minute clinic.
Sydney were simply unable to contain the young fullback who had a game-high 214 metres to go along with four line breaks, three try assists and a try of his own.
Melbourne were impressive across the board with nine players running for more than 100 metres.
Their work with the football was simply sublime, completing 37/39 sets on the back of 60% possession and just three errors.
Despite losing Blake Green (calf strain) prior to kick-off, Storm were on the front foot from the outset when Marika Koroibete turned a kick return on his own goal line into a 30m gain.
Melbourne then marched up to halfway before a string of passes saw Ryan Morgan break the line and pass to Vunivalu who capped off the brilliant 100m team play.
They edged further in front on 19th minutes and it was again the right edge that would play the decisive hand.
Morgan broke through again and with two defenders on him managed to offload to Vunivalu. The young winger then somehow found his way through the wall of bodies on the touchline to dive over and secure yet another double.
Cameron Smith then came up with a touchline conversion to savour as he slipped over whilst striking the ball yet still sent the ball straight through the middle of the uprights.
The Roosters should have hit the scoreboard in the 28th minute but Blake Ferguson fell over his own feet when he appeared certain to score.
In a first half that saw them complete 18 of 20 sets, the men in purple were in no mood for forgiveness and hit the scoreboard again just two minutes later.
Kevin Proctor was the beneficiary on this occasion from yet another swift move to the right. The Kiwi spun out of a tackle to fall over the line for his third try of the season and an 18-0 half-time lead.
Storm may have set up the win in the first half and it would not take long for them to seal it.
The long-sleeved, trend setter Cheyse Blair scored 10 minutes after the restart before some one-two magic between Storm's No.1 & No.7 would commence the purple party.
A Cronk inside pass sent Munster through and the dynamic fullback returned the favour to send Cronk under the posts for a 28-0 lead.
The champion halfback would make it three tries in eight minutes for Melbourne as he went over again for his 9th try of the season.
After coming up with two try assists, two line breaks and 180 metres to that point, Munster was finally rewarded with a try of his own on 64 minutes.
Vunivalu then added even more icing to the purple cake with five minutes to play to cap off a record-breaking night.
