File Type Efficiency

What would be the ideal file type to process with? I have the option of using Tiff, DNG, ARW.

Would DNG and ARW have better accuracy than tiff?
I feel Like DNG takes longer to process with, maybe because of the higher compression.
Is an uncompressed Tiff faster than the other file types?

Hi Steven
Best if you use RAW + DNG, and use TIF or JPG as source data.
