The following RAID types are supported on Precision 7865 Tower workstations:

● RAID 0

● RAID 1

● RAID 5

● RAID 10

● Volume (Just a Bunch Of Disks - JBOD)

● RAIDABLE or RAID Ready

RAID 0 splits or stripes data across two or more drives for faster read and write performance. It uses more space compared to

other RAID types, and performance increases as the number of drives increases. However, if any drive in the array fails, all the

data is lost because there is no data redundancy.

The following are the key features of RAID 0:

● Two or more drives of the same size are required for RAID 0.

● A single-drive RAID 0 volume is almost equivalent to using raw drives in JBOD mode.

● In multiple-drive RAID 0 volumes, read and write operations are shared concurrently across multiple platters and heads.

Therefore, it provides better performance.

● The total volume capacity as seen by the operating system is equal to the sum of the individual-drive capacities. For

example, if you use four drives of 1 TB size, you get 4 x 1 TB = 4 TB.

The following figure illustrates that the total volume capacity of four 1 TB hard drives in a RAID 0 array is equivalent to one 4 TB

hard drive, and that there is no data redundancy.
