IBM has demonstrated a high-speed storage system that uses solid-state memory and a parallel file system

With an eye toward helping tomorrow's data-deluged organizations, IBM researchers have created a super-fast storage system capable of scanning in 10 billion files in 43 minutes.

This system handily bested their previous system, demonstrated at Supercomputing 2007, which scanned 1 billion files in three hours.
