I have loaded 550 Mb of GeoTIFF files (PackBits compressed) into ArcSDE
8.2 on Oracle 8.1.7. That resulted in a 110 Mb increase in used space on
the server, so I can't really recognize your double/triple? This was
including pyramids and using LZ77 compression (loss-less).
Since I'm about to load a total of 30 Gb of TIFF files, I find this
discussion very interesting.
