DiskMaster 45
When the settings are made, the DiskMaster system
starts formatting the disks. This procedure will destroy all
the data on the disks. Make sure You have backed up
any important data on the disks before the format
process. It may require some times; do not perform other
jobs during hard drive formatting
There are 3 differents RAID mode:
RAID 0= RAID 0, known as disk striping, has
generally the best performance, but does not offer
any redundancy. In this level, data is broken into
small units called sectors, and sectors are distributed
across all disks in the array. As it does not provide
any data protection, if any disk in the array fails then
all data in the array is lost. Such stripes allocation
allows to enhance I/O performance.
RAID 1= RAID Level 1, known as disk mirroring, is a
popular approach to protect data from adisk failure.
To implement RAID Level 1, you need at least two
physical hard drives. As the disks are paired up, all
disk writes are duplicated on both disks. You can
back up data without interruption using this algorithm.
In case of a disk failure, the system can continue to
run without being affected.
JBOD=JBOD (Just a Bunch Of Disks) is a group of
disks. JBOD is not technically RAID but “disk
spanning.” In this mode, all the disks are grouped
together so they appears as a large single disk. Each
disk can operate independently and is seen as an
individual disk. Therefore, the total capacity of JBOD
is the sum of the capacities of each disk. This allows
the user to add disks until the desired total capacity is
reached. Since JBOD provides no performance
increase and data protection, it is seldom used.
