3. RAID0 striping volume
The Disks are configured in parallel so that they are all being used at once to store
data, as if they were one Disk in summation. Because the data is saved to each Disk in
parallel, many files of low capacity are read simultaneously but with superior efficiency.
Many low capacity files are read because multiple blocks of data are stored to each
Disk, though the performance is excellent at this time. In order to secure data stored,
Information is not read when at least one Disk is damaged. Subsequently, if the Disk is
damaged, the saved data in the volume will be lost.
The storage capacity of the volume as a whole is the sum of the capacities of all of the
Disks.
This technique must not be used for the saving of important data, but rather for fast
data access and for maintenance of the security of its volume capacity.
4. JBOD Linear volume
The Disks are configured in series so that they are all being used at once to store
data, as if they were one Disk in summation. The volume's storage capacity can be
maximized, as the data is stored to the Disks in sequence. Data must not be written
in the event of a damaged Disk to safeguard saving capacity. In this way, if a Disk is
damaged, saved date in the volume will be lost. The storage capacity of the volume as
a whole is the sum of the capacities of all of the Disks. To maximize the safeguard of
capacity of the volume, saving of important data is not recommended.
