Your system might have a file creation utility that
enables you to override the file system limitations and create file
systems (volumes) greater than the space on a single disk. You can
use this utility to allocate SPD Engine libraries that span multiple
disk devices, such as RAID. RAID configurations use a technique called
disk striping that can significantly enhance I/O. For more information
about disk striping and RAID, see “SPD Engine Disk I/O Setup”
