RAID LEVELS

Many of our customers are interested in knowing more about the different raid levels available on our Sonata Trading Computers. This article will explain the difference so they can made clearer decisions on what RAID to have their computers configured with.

First off, what does RAID stand for? It stands for Redundant Array of Inexpensive Disks. To configure a RAID on one of our computers, you must have at least 2 hard disk drives that work.

The reason for a RAID is to give the user better performance or security redundancy, or even a possibility of giving both.

The RAID is usually based on a motherboard RAID controller and used in combination with drivers.

You can protect loss of your data when you use one of the following fault-tolerant raid levels:

RAID 1
RAID 3
RAID 5
RAID 0 + 1

When data is stored on more than 1 drive, if one drive fails then computer can continue without any down time. A failed drive can then be removed and a replacement put on the system allowing the fault-tolerance to be restored.

RAID 0

Using RAID 0 gives the computer excellent performance in both write and read applications.
