 ## RAID0

     RAID0 splits data across a multiple-disks array. The ideal setup is equaly-sized disks since the total storage used in a RAID0 arrangement is equal to the lower storage disk space times the total amount of disks. I a array of one 120Gb disk and one 360Gb disk, the total storage available would be 240 Gb.
     RAID0 create stripes of data so disk operations are n-times faster, n being the total amount of disks available. It also distributes I/O costs between all disks making it a very fast storage system. RAID0 **doesn't implements parity** or even any **fault tolerance**, so the failure of one single disk in the array will result in total data loss. 
     Besides fastness, RAID0 also is a good system to create large amounts of data storage units with lesser disks, since all disks in the array have unique information and, having equaly-sized units, uses 100% it's fisical capability as storage.
