1Ds Mark III files are enormous

1Ds Mark III file sizes are insane. The RAW files are roughly 25MB each (compared to 6MB for the 10D, 6-9MB for the 1D Mark II, and 10-12MB for the 1Ds) and the extracted TIFF files are 120MB each! Yikes. From a pure full-frame to full-frame comparison, the 1Ds Mark III files are >100% larger than those of the 1Ds. Needless to say, the resolution too has gone up to 21 megapixels from the 11 megapixels offered by the 1Ds.

At this rate I am going to need a LOT of storage space. Fortunately DVD-RWs are cheap, and I have a DVD burner!
