Eraser and ISO files

I am wondering about how Eraser handles ISO files. I notice that it erases ISO files much faster than it erases the individual files the ISO was created from. I'm talking about less than a minute for an ISO of the entire contents of a DVD-R, i.e., 4.3+ GBs, as opposed to maybe 15 minutes to erase the actual files the ISO was created from. What's going on? Is it just due to the fact that it is one big file and the individual files are many or is something going on that might compromise the security of the erasure?
