Notts' 39-run win against Essex at Trent Bridge on Monday sees them return to the showpiece event at Edgbaston for the first time since 2010.
Read, who has won a Lord's one-day final and two County Championship titles with Notts, has been part their two previous Finals Day campaigns.
"Maybe this is our year," he said.
"We go to Finals Day full of confidence and hopefully pick up some silverware."
The only time Nottinghamshire have reached the final of the competition was in 2006 at Trent Bridge, with the Outlaws missing out on a maiden title when beaten by East Midlands rivals Leicestershire in the decider.
Samit Patel ensured Notts progressed on Monday with a superb spell of 4-20 as the visitors collapsed to 123 all out chasing what seemed a modest target of 163.
All-rounder Patel said victory brought a sense of "relief from everyone" as Notts had previously fallen at the quarter-final stage in four of the past five years.
Talking to BBC Radio Nottingham, the 31-year-old said: "We knew this was a big game for us.
"We will watch all the other quarter-finals and do as much homework as we can.
"It's good get Finals Day, but we'd like to go on and win it now."

American billionaire Michael Eisner will address fans on Thursday with details of his £5.67m offer for 100% of the promoted League Two club.
Shareholders and PST members will vote on the former Walt Disney chief executive's proposals later this month.
"I don't think that we should think this is our only chance," Brown said.
Eisner, 75, has presented the terms of his offer before a town hall-style meeting at Portsmouth's Guildhall on Thursday.
Among his proposals are a further £10m equity investment, as well as the removal of three PST members from the club's nine-strong board.
The PST own 48% of the club after helping bring it out of administration in 2013.
Rather than instructing shareholders to vote in favour of Eisner's deal, the PST and club presidents have told fans to make up their own minds.
"What people need to do is see if it's the right option and the right person," Brown told BBC Radio Solent.
"That's the difficulty for people as you're dealing with somebody you don't know.
"Thursday is a chance for some people to look him in the eye in a public forum and ask him some questions and we'll see what he has got to say then.
"It's a huge decision about the future of the club, one that will define the path in goes on in the next few years. The beauty is that it's the fans that are making it."
Nottinghamshire go to Finals Day confident of winning their first T20 Blast title, says long-serving wicketkeeper Chris Read.
