loss will occur.
A linear configuration is similar to using multiple hard disks in a regular computer. Each
disk is an independent entity, and the data on it is self-contained. You can add or remove
the disks without affecting the other disks. All the available disk space is used for data.
If your storage system has only one disk, you must use a linear configuration. However,
you can use a linear configuration for two, three, or four disks as well.
data loss will occur.
Instead of writing all the data to one disk in a linear fashion, some bytes are written to one
disk, and other bytes are written to another. Performance is faster because reading and
writing activities can occur on multiple disks simultaneously. All the available disk space
is used for data.
For RAID 0, your storage system must have at least two disks. However, you can use
RAID 0 with three or four disks as well, and the disks can be any size.
