16. y during heavy load situations This situation allows all drives to work concurrently on different I O operations and thus maximize the number of simultaneous I O operations that can be performed by the array User s Manual NAS System Definition of RAID Levels RAID 0 is typically defined as a group of striped disk drives without parity or data redundancy RAID O 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 Writes can occur simultaneously on every drive pata Reads can occur simultaneously on every drive 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 sin
