RAID 0 Striping
Description
RAID 0 is a performance oriented striped data mapping technique across two or more
drives.
Uniformly sized blocks of storage are assigned in regular sequence to all of an array's disks.
The controller divides incoming data into as many chunks as there are drives and then
writes that data across independent disks. The writing technique is called "striping." Since
all disk write heads work independently, RAID 0 provides the fastest performance RAID
configuration.
Fault Tolerance Cost
RAID 0 arrays have no fault tolerance characteristics beyond that provided by each
individual disk. As such, there is no utilization space cost. 100% of the drive capacity is
available for user data.
Performance
RAID 0 provides high I/O performance at low inherent cost as no additional disks are
required and the entire array disk space is used for user data. Fault Tolerance Provided
Application Focus
RAID 0 is often used in managing transient data that has to be processed quickly and then
deleted.
The extremely high data throughput rates are especially valuable for applications using large
files.
Array Size
The array can be from 2 to 16 drives.
