RAID-0
RAID-0 provides improved performance in writing data to or
reading data from your computer’s internal hard disks.
RAID-0 is configured by creating an array which specifies
the hard disks which striped data will be written to or read
from. For your computer, you will create an array consisting
of the computer’s primary internal hard disk and secondary
internal hard disk.
When a RAID-0 array is configured, data is written to the
internal hard disks using a technique called striping.
The computer collects the data to be written until a specific
amount of data has been collected. Then, the data is equally
divided. One portion (stripe) is written to the primary hard
disk. The other portion (stripe) is written to the secondary
hard disk.
The two portions of data are simultaneously written to the
hard disks. That way, a file that would take normally 30
seconds to write to a single hard disk would take
approximately 15 seconds to write simultaneously to the two
hard disks in the RAID-0 array.
The speed in reading data from the hard disks is also
improved as data is simultaneously read from both hard disks.
A file that would normally take 30 seconds to retrieve would
take approximately 15 seconds to read from the RAID-0
array.
If you want to discontinue the process of striping, see
“Breaking a RAID-0 array (striping)” on page 246.
