FastCopy is a file copy and synchronization tool with a variety of available extras. It uses different strategies (multi-threading, buffering) to help ensure maximum device throughput, as well as optional verification to make sure data is transferred correctly. It does not use the system cache, so other processes do not get bogged down during the copy process and a speed setting is also available, including pause. It supports Unix-style include/exclude wildcards filters.
Alternatively, PortableApps.com packages the last open source version as FastCopy Portable.
