RAID arrays are ideal for video editing servers.
Video editors have two pressing needs, performance and redundancy.
RAID Arrays Offer Extraordinary Performance for Video Editors
One is performance. Video files, particularly with sound tracks, are very large and have became much larger with the advent of High Definition. Video editors need to store these video editing files and then feed them into workstations. Moreover, multiple video editors often work on the same files concurrently. Consequently, they need very fast storage to forward the video editing to workstations and save footage as it is edited. This is why video editing facilities prefer RAID arrays. Arrays provide extraordinary I/O speeds because they read data from multiple disks simultaneously. Read speeds are further accelerated when arrays are provisioned with solid state drives (SSDs).
Redundant RAID Configurations to Avoid Lost Video Footage
The second need is redundancy. Video editing footage is costly to create and to eliminate the risk of any loss, files must be securely stored. Yet disks can and do fail in storage systems. This is another reason why video editors commonly use RAID solutions. Depending on their configuration, RAID arrays can avoid data loss should a disk fail.
Popular configurations are RAID 5 and 6. RAID 5 offers both performance and redundancy. It requires at least three disks, although four or more are usually deployed, with one serving as the parity disk that ensures a full recovery should one of the other disks fail. If the parity disk fails, no problem. Your video editing data resides on the other disks and you simply need to rebuild the parity disk. RAID 6 offers additional redundancy. Even in the unlikely event that two hard drives die, you will not lose a second of your video.
