What geoprocessing tool is the fastest for copying feature datasets from SDE to fgdb?

I want to make a model in ModelBuilder that copies an entire featuredataset from my SDE database to a file geodatabase. I don't know what the fastest tool is. I tried "Copy element" but that is painstakingly slow compared to if you copy-pasting in ArcCatalog. Featureclass to Geodatabase, only copies the featureclasses in the dataset, and places them in the root of the fgdb. Featureclass to featureclass is a lot of drag and dropping, and I don't know about the speed.

I would love to know what the fastest tool for this job is.

do you mean with "Copy element" as arcpy.Copy_management(in_data, out_data)? – Aragon Nov 1 '12 at 8:38
@Aragon, Actually, Im not sure. But I'll convert the model to python and see. – Morten Nov 1 '12 at 8:42
@Aragon, Yes it was Copy_management(in_data, out_data) – Morten Nov 1 '12 at 8:56
@Aragon. The tool is much, much faster in python than in ModelBuilder... why??? – Morten Nov 1 '12 at 10:15
ModelBuilder is likely to have a layer or several of abstraction above the Python. Its the price you pay for a pretty interface unfortunately. – GIS-Jonathan Nov 1 '12 at 10:45
