Jordan,
I've dealt with ERDAS Imagine files larger than 10 GB on a regular basis.
I have occasionally tried to reproject and merge all of the 1 m NAIP
imagery tiles for North Carolina into 1 BigTIFF > 500GB with gdal. Any
parallelizaion work for open source geospatial tools would be welcome :-).

Our provincial DEM is a 3.5GB Geotiff which is of 48800x58000 size.
Another file which I recently had to import was a 4GB Geotiff with
21550 bands. Finally, in remote sensing, you can quickly generate
quickly files in the multi-GB range.
