Product Manual
The disk array’s data capacity is equal to the number of disk drive members multiplied by the
smallest drive’s capacity. For example, one 100 GB and three 120 GB drives form a 400 GB (4 x
100 GB) disk array instead of 460 GB.
If physical drives of different capacities are used, there is unused capacity on the larger drives.
RAID 0 logical drives on
Vess
consist of one or more physical drives.
Recommended Applications for RAID 0:
• Image Editing
• Pre-Press Applications
• Any application requiring high
Advantages
Disadvantages
• Implements a striped disk array, the data is
broken down into blocks and each block is
written to a separate disk drive
• I/O performance is greatly improved by
spreading the I/O load across many channels
and drives
• No parity calculation overhead is involved
• Not a true RAID because it is not fault-
tolerant
• The failure of just one drive results in all
data in an disk array being lost
• Should not be used in mission critical
environments
