What is RAID 0?

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.

• Minimum number of drives: 2
• Strengths: Highest performance.
• Weaknesses: No data protection; One drive fails, all data is lost.

DRIVE 1	DRIVE 2
Data A	Data A
Data B	Data B
Data C	Data C

RAID Levels instruction: RAID 0 - RAID 1 - RAID 2 - RAID 3 - RAID 4 - RAID 5 - RAID 0/1 (or RAID 10)

Types Of RAID: Hardware-based Raid | Software-based Raid
