This is about the same speed as the Cirrus parachute. To be fair it still flys forward, so it’s not comparable. But impressive!
That was dubbed the "Falling Leaf" maneuver on the old Diamond forum. I also like demonstrating flying around with the Stall warning horn blaring at 42 KIAS, holding altitude, making gentle turns. Never fails to impress other pilots.

Actually a Cirrus descends under parachute at about 1700 fpm.

But with very little lateral speed though subject to winds, of course.

If I bought a new one I would consider putting it in DiamondShare. Does anyone have experience with that program?
Marco, I'm in the process of purchasing a DA40 NG with the Diamondshare program. Happy to discuss my (admittedly minimal) experience with the program. Feel free to PM me. If you can't find an NG near Boston, I know that Take Flight in Montgomery, NY, has a brand new DA40 NG available for training.

Here is a nice new video about the safety features of the DA62. As mentioned in the video many of these are valid for the DA40 as well:

Consider the case of 21 KT wind at the surface. In the Cirrus chute, you crunch uncontrollaby at 1700 fpm and 21 KT ground speed into whatever obstacle happens to be in your path. In the DA40 "Shaking Leaf" scenario, you steer into the wind and continue to fly the aircraft around any obstacles, touching down at that same 21 KT ground speed, but at less than half the vertical velocity of the Cirrus in chute.

All very true, however if I was in IMC over mountains or other difficult terrain, or water, a chute to pull is a very good option to have.

It will be interesting to see if Diamond will offer a chute on the DA50. Again, just my view that others may not agree with, but I think if the DA50 has a chute as standard or as an option, they have potential to take some serious share from Cirrus. The market has spoken, a chute on single engine aircraft makes sense to a lot of people - especially those people who buy new single engine aircraft - otherwise Cirrus would not be as successful as they are. Granted, Cirrus has a number of other benefits that have resonated with the market, yet the chute is a key differentiator and will continue to be so.

This has been tried a few times and has not turned out well in all but one that I'm aware of. The most extreme was this: https://aviation-safety.net/wikibase/wiki.php?id=44566

Totally agree.

(Yes, I know the two statements above appear to be in opposition of each other, but one is about the "truth" of parachutes and the situation, the other answer is about the power of marketing.)

I love how people cherry accidents :)
You pull the chute outside design envelop, you are now in a test plane.
