Also keep in mind that on modern hardware most hash algorithms are IO limited. If you just wrote that file out to disk at least parts of it are likely to be either buffered in the VM or cached there so the time spent actually hashing the file (for large files) should be less then the ammount of time it takes to physically write the file to disk.
