Data striping

By spreading segments across multiple devices which can be accessed concurrently, total data throughput is increased.

One method of striping is done by interleaving sequential segments on storage devices in a round-robin fashion from the beginning of the data sequence.

Increased throughput allows the data processing device to continue its work without interruption, and thereby finish its procedures more quickly.

[5] Wide striping occurs when chunks of data are spread across multiple arrays, possibly all the drives in the system.

Data striping is used in some databases, such as Sybase, and in certain RAID devices under software or hardware control, such as IBM's 9394 RAMAC Array subsystem.

An example of data striping. Files A and B, of four blocks each are spread over disks D1 to D3.
