RAID 0 - Data striping without redundancy (no protection). Optimized for Performance
RAID 0 uses striping to write data across multiple drives simultaneously. This means that when you write a 5GB file across 5 drives, 1GB of data is written to each drive. Parallel reading of data from multiple drives can have a significant positive impact on performance.
The trade-off with RAID 0 is that if one of those drives fail, all of your data is lost and you must retore from backup.
RAID 0 is an excellent choice for cache servers, where the actual data being stored is of little value, but performance is very important.
