Item Action
Create Single
Disk Volume
If you don’t want to create the disk array model, perhaps you can
choose the mode. If install two hard disks, you should create two
volumes, also system files stored the first volume and the two volumes
without correlation.
Note: This mode can also be one hard disk, and then you just
need create one volume.
Create RAID 0
Volume
RAID 0, also known as Striping or Stripe, It represents the highest of
all RAID levels of storage performance. Improve the performance of
RAID 0 storage principle is the continuous data access across two
disks, This data parallel operation on the bus can take advantage of
the bandwidth, significantly improving the speed of disk storage.
If one of disks has a smaller capacity, the total array size will be based
on the smaller capacity multiplied by 2. For example, if a 120GB disk
is striped together with a 100GB disk, the size of the array will be
200GB.
Note: if one hard disk is unhealthy, all data is lost. And this mode
is not conducive to data security storage.
Create RAID 1
Volume
RAID 1 also known as Mirror or Mirroring (mirroring), and its purpose
is to ensure maximum data availability and user-repairable. RAID 1
mode is the user data written to disk one hundred percent
automatically copied to another hard disk. Mirror, although not
improve storage performance, but because of its high data security,
