It takes even longer once you start stopping.
Believe me, you will want to stop.
There are scenic views everywhere. A stream here. A cliff there. Every turn and mile has something to see.
Realistically it will take you 4-7 hours to get there.
For most people its get there then turn around and drive back to their resort. I had plans on camping. Just beyond Hana itself you reenter Haleakala National Park and in addition to the Seven Scared Pools there is a campground. Here I set up camp along the coast and was able to enjoy the quiet side of Maui.

Take a look at the top image here, it is a view along the coast. If you look close you can see the road cut in the trees where a narrow two lane road is hugging the cliffs. Yes, that is the drive.

Once past Hana the road becomes even narrower, really just a lane and half wide with no stripe. When two cars go past each other you have to slow to a crawl and go very slow, each of you a time almost off the road. In some places off the road mean hanging on a cliff.
More than once I had to back up to let someone through.
All in all a beautiful drive and the payoff of getting to camp there made it so nice. A sure thumbs up on the drive and camping along the coast for a very different Hawaii experience.
