Raid explained

April 30, 2009

About 12 years ago I went to work with an international company in Sydney, Australia. I was a young IT guy and had only been in IT for about 6 years at the time and had mostly worked on desktops and small microsoft networks.

While working there I met a number of experienced IT people and gained a vast wealth of knowledge and I am greatful for the experience that I gained. One of the people that I learned a great deal from was the Lotus Notes administrator. I once asked him what was this RAID thing all about, he pointed me to a document that he had created in one of the company help databases and I instantly had a working knowledge of RAID.

An excerpt from Wikipedia below describes where the name RAID came from.

“RAID is an acronym first defined by David A. Patterson, Garth A. Gibson and Randy Katz at the University of California, Berkeley in 1987 to describe a Redundant Array of Inexpensive Disks,[1] a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy.”

“More recently, marketers representing industry RAID manufacturers have revised the term to Redundant Array of Independent Disks, a convenient means of avoiding the expectation of low cost associated with the term inexpensive”

This video below should give you an idea of what RAID is all about.
