qpress is an easy-to-use and portable file archiver that uses QuickLZ and that was designed to utilize fast storage systems to their maximum. It's often faster than file copy because the destination is smaller than the source.
Here are some key features of "qpress":
· multiple cores, reaching upto 1.1 Gbyte/s in-memory compression on a quad core Xeon 64-bit file sizes and tested with terabyte sized archives containing millions of files and directories
· pipes and redirection and *nix-like behaviour for scripting and flexibility
· Adler32 checksums to ensure that decompressed data has not been corrupted
· data recovery of damaged archives with 64 Kbyte grannularity
· unbuffered disk I/O to prevent disk cache of other applications from being flushed
