Asgard hyperdrives have routinely proven capable of crossing intergalactic distances in a matter of days, even hours, and are a necessity for the Tau'ri to continue their intergalactic endeavors.
[edit] Functions
The precise speed of a vessel equipped with an Asgard hyperdrive appears to be directly proportionate to the ship's available power: the Prometheus needed months to travel between the Milky Way and Pegasus galaxies (where the more advanced Daedalus made the trip in about four days with a ZPM tied into its power systems), and an Asgard O'Neill-class vessel traveled from the Ida galaxy to the Milky Way in only a few hours. Ordinarily, a Daedalus-class battlecruiser requires around 18 days to make the trip; the drive could be modified to allow the ship to travel faster, but at the risk of burning it out. Even without a ZPM or comparable power source backing them these are some of the fastest hyperdrives known to exist, surpassed only by a fully-powered stardrive. (SG1: "Prometheus", "Prometheus Unbound") (ATL: "The Siege, Part 2", "Critical Mass")
While in hyperspace the shields and weapons systems of a ship using an Asgard hyperdrive are offline, due to the fact that the full power of the vessel's generators is required. As a result, a ship using an Asgard hyperdrive can be destroyed if a nearby vessel in hyperspace self-destructs; however this occurrence is highly unlikely, as no other hyperdrive has been seen keeping equal pace with them. Asgard ships have the ability to tow other vessels in their hyperspace field, but this causes the total travel time of the journey to be lengthened exponentially (it is unknown if the hyperdrives equipped on Tau'ri vessels have the same capability). (ATL: "Unnatural Selection", "New Order, Part 1")
[edit] History
After having limited success with their own attempts at developing a working hyperdrive, the Tau'ri were first given Asgard hyperdrive technology as thanks for their help in fighting the Replicators. Asgard hyperdrives are now standard on all Tau'ri starships. However, Earth ships use considerably weaker power sources when compared to Asgard vessels, though shortly prior to their extinction the Asgard installed an advanced power core aboard the Odyssey. It is unclear whether this new power core actually improved the Odyssey's performance, as the ship was already using a ZPM at that point. (SG1: "Unending") (ATL: "Echoes")
