RAID 0 

is typically defined as a group of striped disk drives without parity or data redundancy. RAID 

0 arrays can be configured with large stripes for multi-user environments or small stripes for single-

user systems that access long sequential records. RAID 0 arrays deliver the best data storage 
efficiency and performance of any array type. The disadvantage is that if one drive in a RAID 0 array 

fails, the entire array fails. 

 

 

 

 

 

 

RAID 1

, also known as disk mirroring, is simply a pair of disk drives that store duplicate data but 

appear to the computer as a single drive. Although striping is not used within a single mirrored drive 

pair, multiple RAID 1 arrays can be striped together to create a single large array consisting of pairs 

of mirrored drives. All writes must go to both drives of a mirrored pair so that the information on the 
drives is kept identical. However, each individual drive can perform simultaneous, independent read 

operations. Mirroring thus doubles the read performance of a single non-mirrored drive and while the 

write performance is unchanged. RAID 1 delivers the best performance of any redundant array type. 

In addition, there is less performance degradation during drive failure than in RAID 5 arrays. 

 

 

 

 
 
 
 
 

RAID 3 

sector-stripes data across groups of drives, but one drive in the group is dedicated to storing 

parity information. RAID 3 relies on the embedded ECC in each sector for error detection. In the case
