(Warhammer 40k) Is there any other way of FTL travel that does not involve either crossing the warp or the webway?

As far as the tech priests can tell, the Necrons' FTL system is based entirely on the material plane. This "inertialess drive" is necessary for them, because they are completely disconnected from the warp, and cannot use any FTL method that involves entering it. This drive basically eliminates the diminishing returns on acceleration that are normally experienced when one approaches the speed of light, so that they can simply accelerate past it. How exactly this is possible is not yet known for certain to the Adeptus Mechanicus, but is presumed to be heretical, and therefore of no interest to mankind, save as a target for condemnation.
