The variation is in the size of the embedded JPEG preview(s),

sensor data.
Some cameras, like my E-1, produce RAW files which are always the
same size because the embedded JPEG preview is set to always fit
within a particular logical file size (not the same as the actual
number of data bytes. And others. like the L1, always have a fixed
RAW file size because they do not embed a JPEG preview in the RAW
file, they put it into a JPEG sidecar file.
I think my darkside raws are uncompressed but they have jpgs imbedded,
too ,and I noticed
the CRW files are different sizes - though not by a lot.... At first I
thought I didnt have jpg
files imbedded until the light bulb went on over my head and I realized
what the file processing
stuff's little "extract jpg files" thingy meant. the extracted files
are only useful for doing a quick
slideshow for "did I get the shot " in terms of info, thoughsince the
quality is low.
