RAID-0 Volumes

A RAID-0 volume (or striped volume) stores data in stripes on two or more physical disks. Data is allocated alternately and evenly to the disks making up the striped volume. RAID-0 volumes can improve the speed of access to the data on disk, but they are not fault tolerant. Click on the link below to see how to create a RAID-0 volume:

Creating a RAID-0 volume

Note the following points:

• At least two physical dynamic disks are needed to create a RAID-0 volume.

• A RAID-0 volume can use a maximum of 32 disks.

• A RAID-0 volume's capacity is limited to the space available on the disk with the smallest available capacity. Try to select disks that have similar amounts of available space.

• Try to use disks that are the same model and from the same manufacturer.

• RAID-0 volumes cannot be extended or mirrored. If you need to make a RAID-0 volume larger by adding another disk, you first have to delete it and then re-create it.
