There are 3 separate types of Raid drivers, Raid 0, Raid1, and Raid5. Raid stands for Redundant Array of uncostly Disks. These drivers are a ideas of hard disks that join to provide large amounts of data storage. The benefit to this process are redundancy, performance, and lower cost. Ibm created the Raid drivers in 1978, however the idea did not take off until the late 1990's. Today the idea is taken off, along with another producer Emc adding their contributions to this process.
To understand the advantages of Raid drivers you must first understand what is meant by the term redundancy. Redundancy, was created to cut the seriousness for errors. This means if a disk fails to provide the data you need, you will be able to retrieve the same data from another disk. This can be done while your computer ideas is on, taking less time to do this process.

Raid 0 is the only one out of the three that does not provide redundancy. The stored data is to be written on two disks, dividing it in half or "striping'. If your disk has errors, all information is lost because there is not a copy. The advantages to Raid 0 are execution and more storage capacity.
The Raid 1 driver takes the mirror advent to redundancy. The data is written on one disk while a second copy is mirrored on another. The result is having another disk of data if the first fails because of errors. However, this means there will be less storage space available.
Raid 5 uses the 3 disk approach, or the " parity block". All data is written on 3 disks providing the best case of redundancy and execution managed by a controller. This means if one disk fails, you can piece together another copy using the two remaining disks.
If you can not conclude which is the good option for you, it is inherent to blend the Raid drivers. For instance, using Raid 0 and Raid 1 to growth the redundancy option.
The more popular the Raid divers become the more they seem to be adapted to other things. Currently Raid drivers are used in external components only, but who knows what the future will bring!
