The number of security cameras in use today is growing exponentially. At the same time, resolutions are getting higher and higher. These two factors are placing heavy demands on servers and storage equipment. Of course, the capacity of these systems is also increasing, but that alone does not make the equipment truly suitable for the most demanding applications - such as camera surveillance. A video stream is not comparable to 'normal' data, for which storage systems are usually designed. This article will explore how these issues can be addressed.

A hard disk residing in a video storage system has a tough life. On a daily basis, large amounts of data are written and read and all sectors are continuously filled to the maximum. A hard disk designed for office applications is not able to manage this work. At first everything seems fine, but anyone closely monitoring the stored images will notice that 'frame drops' are the...
