FastCopy - a neat (fast!) copy utility

FasCopy is a smart copy utility that copies files very quickly. It also supports file moves and deletes.
It is clever enough to detect whether the copy is from and to the same HDD and uses a different copy strategy accordingly.

As stated on its web site,

Diff HDD	Reading and writing are processed respectively in parallel by another thread.
Same HDD	Reading are processed until the big buffer fills. When the big buffer filled, writing are started and processed in bulk.
