An Introduction To Raid – Greater Reliability, Economical and Faster Hard Drive Units
The first question which comes to mind is what is a raid setup on a computer system?
This depends on the person you pose the question to
The acronym is explained as “Redundant Array of Individual Drives “and “Redundant Array of Inexpensive Drives”. The acronym for this is the shortened term “RAID” and it is a hard drive system.

It is quite easily heard that “It is not if you hard drive will fail. It is at what point in time your hard drive will fail.”
Even in case of a backup file, the last bit of data that was not backed up, that will always be lost in case of a hard drive failure.
With RAID all this become ancient history, you can have capacities which are much greater and can avoid the oozing of data in case of a failure of the hard drive.
It is now also cost effective, as it can now be completed with the help of standard commercially available hard drives thus offering you the peace of mind.
In its most simple explanation it can be defines as a parallel sequence of hard drives.
The RAID system controller or the host adapter sits on the computer side, between one higher stream and on the hard drive side, several lower rate data streams. At the time of the writing of the disk the process called striping is employed in which the host adapter breaks the high stream data into many synchronized streams, one for ever disk. When the data is finally read, the host adapter coordinates the data from each stream on every disk and sends the results as combined data to the computer.
The matter of redundancy is what makes RAID such a useful thing in such case.
