Since this is a LINUX forum, my assumption is that you are investigating software-RAID 0, which is utilized via the /dev/md driver. In this context, it is a way to arrange two or more PARTITIONS (not necessarily hard drives) to improve read or write performance under certain I/O loads. You could take, for example a single HDD that you are booted to, and then carve out two partitions of 100GB, and create a RAID0 stripe of them using the raid tools or other mechanism. You would end up with a /dev/md0 array and a file system that mounts the /dev/md0.

Performance of the filesystem mounted on the md0 array would be able to sustain higher throughput from a single disk drive then if you didn't create a 200GB usable RAID0 array.
