Hi Robert, Its all down to how well the data is compressed by the drive.... from your details I would say you have some medium sized databases which are backed up and compressed, some zip files that are already compressed to the limit and lots of text files in one place that can be compressed by up to 80%.
If all your tapes were storing 120GB or more, I would have suggested that you should experiment with compression at source to free off some network bandwidth. It all looks normal to me... Don't worry! (BTW: I have a couple of Scalar100's and an LTO library with very similar results) If you have lots of free time, you could set up different backups for different data types/locations based on compressability, then compress some at source.... personally I am too busy!!
