Storage: Redundancy / RAID Statistics
by Ethan Ace, posted on Jan 23, 2012Increasingly, users expect their data will never be lost. From using web apps like Google mail to storing files with services like Dropbox, it is easier than ever to keep your data forever. However, what about surveillance video? How common is it for surveillance video to be protected against hard drive loss? In this report, we provide statistics and insights from 100 integrators around the world on their approaches to protecting surveillance storage.
Historically, using RAID for video surveillance has not been common. With relatively large storage amounts at debatable levels of value, the cost of providing redundancy was often significantly more than could be justified. On the other hand, the cost of RAID has clearly dropped and its availability in common products is increasing. Do these trends now reach a point where the majority or most everyone in surveillance is using RAID?
The Question
We were curious to see how often it was being deployed in production. In order to see what integrators are really installing in the field, we asked the following question of the 100 respondents to our Winter 2012 poll:
Inside we break down the results in the following manner:
- What percentage overall of video surveillance installs are using redundancy/RAID?
- How does that support break down among integrators?
- How does IP camera adoption impact redundancy/RAID usage? We compare adoption amongst integrators using 80%+ analog camera, 50%+ analog cameras, 50%+ IP cameras and 80%+ IP cameras.
- How does system size impact redundancy/RAID usage? We compare adoption amongst integrators who typically deploy less than 8 cameras to those who typically deploy more than 20 cameras and those who typically deploy more than 50 cameras?
Finally, we will show you that while redundancy/RAID support has come a long way, there is still a ways to go before it becomes universal.
