An Introduction to RAID 0 Hard Drive Array

RAID, redundant array of independent disks (also called redundant array of inexpensive disks) is a method of logically combining two or more physical disks into one (logical) storage unit. In theory, running two or more disks in a RAID 0 array will give you increases speed and storage capacity. However, the downside to a RAID 0 configuration is the increased risk of hard drive failure and data loss. If one drive fails, all data will be lost because the data is stripped across multiple drives. 
What Level of RAID Technology do I need?
Several types of RAID are in use called RAID levels. Commonly used levels are RAID 0 through RAID 6. Level 0 and level 1 are common in home or business desktop PCs.
RAID 0 is not a true RAID because no redundancy (automatic protection in case of disk failure). RAID 0 is actually a stripped drive, spreading data over two drives so it can be read or write quickly. For example to write a large file, instead of writing to a single drive it is much faster to stripe data and write to multiple drives simultaneouslyWhile account we can cull abstracts from all drives in parallel. Theoretically, bifold harder deejay performance, but there are some issues and overheads complex so the accretion is not consistently double. RAID 0 increases the affairs of abstracts accident because any harder deejay abortion will accompany accident of all abstracts on both drives.
