Wraith hyperdrive is likely faster than OTL Warp, not so sure about nuTrek though. If you look at the script or novelisation of First Contact it took the Ent-E around 3 days to get to Earth (there is a cut scene obviously). In nuTrek that do Earth to Vulcan in five minutes (change of a shirt) which is 12 light years away. Then reach Kronos is hours in nuTrek, or virtually instantly on the way back. In short nuTrek is hideously fast, and it is why Click This made mention of it resembling slipstream which can cross around 10k lyrs in an hour.

Hope that helps you gauge it's rough velocity?
