As a curiosity I was wondering if anyone could share how long it takes on average to carve a drive. I know this can very from system to system, but was curious for example how long it would take to carve 1 file header through a large image in excess of 80gb. I have been revamping my carving program and I have noticed that my new single threaded application is much faster than my existing multi-threaded carver while providing the same accuracy.
So the question is, what times are you getting and for what size of hard drive with a single header.
I am not sure how a multithreaded program would help with a carve for a single string. The slow part of tyhe program is reading the raw disk. To do with with more than a single thread will just cause disk thrashing, and hence slow it all down.
Most carving is for multiple file types, and often will include saving files and hashing them.
Speed can vary considerably depending level of carving, could range from 10GB/hour to 100GB/hour (or more or less)
