Volume Group Configuration Relative Read Performance Relative Write Performance for Large Sequential Access for Large Sequential Access RAID 0 The read and write performance of a RAID 0 volume group increases as the multiple of the number of disks in the volume group. For example, a 4-disk RAID 0 volume group will achieve close to four times the performance of a single disk.

Relative Write Performance

RAID 0
The read and write performance of a RAID 0 volume group
increases as the multiple of the number of disks in the volume
group. For example, a 4-disk RAID 0 volume group will achieve
close to four times the performance of a single disk.
