I briefly touched on IP video surveillance storage options in a previous post. 

Ronen Issac, over at the Security Info Watch Blog, has done a much better job, including some very useful graphics, at explaining the intricacies of the redundant storage system known as RAID. 

From his post, Overview of RAID for IP Video Storage:

Storage is a big part of IP video security and so I thought I would start a small series of video storage starting with the basics. Today we will discuss RAID. RAID has been discussed many (x4) times throughout the years but I still get questions about it. What is it, what is the best choice for RAID for my VMS, etc. So here we go.

There are 4 major types of RAID 0, 1, 5 & 6. There are then combinations of two of the above like RAID 10, 50 & 60. We will discuss each briefly.
