When you are working with RAID 0 volumes, consider the following:
Use components that are each on different controllers to increase the number of simultaneous reads and writes that can be performed.
Do not create a stripe from an existing file system or data. Doing so will destroy data. Instead, use a concatenation. (You can create a stripe from existing data, but you must dump and restore the data to the volume.)
Use the same size disk components for stripes. Striping different sized components results in wasted disk space.
Set up a stripe's interlace value to better match the I/O requests made by the system or applications.
Because a stripe or concatenation does not contain replicated data, when such a volume has a component failure you must replace the component, re-create the stripe or concatenation, and restore data from a backup.
When you recreate a stripe or concatenation, use a replacement component that has at least the same size as the failed component.
