R A I D 0 R A I D 0 R A I D 0 R A I D 0 R A I D 0 (Data striping) optimizes two identical hard disk drives to read and
write data in parallel, interleaved stacks. Two hard disks perform the same
work as a single drive but at a sustained data transfer rate, double that of
a single disk alone, thus improving data access and storage. Use of two
new identical hard disk drives is required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from RAID 1 RAID 1 RAID 1 RAID 1
one drive to a second drive. If one drive fails, the disk array management
software directs all applications to the surviving drive as it contains a
complete copy of the data in the other drive. This RAID configuration provides
data protection and increases fault tolerance to the entire system. Use two
new drives or use an existing drive and a new drive for this setup. The new
drive must be of the same size or larger than the existing drive.
R A I D 0 + 1 R A I D 0 + 1 is data striping and data mirroring combined without parity R A I D 0 + 1 R A I D 0 + 1 R A I D 0 + 1
(redundancy data) having to be calculated and written. With the RAID 0+1
configuration you get all the benefits of both RAID 0 and RAID 1
configurations. Use four new hard disk drives or use an existing drive and
three new drives for this setup.
J B O D J B O D J B O D J B O D J B O D (Spanning) stands for J u s t a B u n c h o f D i s k s
disk drives that are not yet configured as a RAID set. This configuration
stores the same data redundantly on multiple disks that appear as a single
disk on the operating system. Spanning does not deliver any advantage
over using separate disks independently and does not provide fault
tolerance or other RAID performance benefits.
