RAID levels. RAID 10 speeds up both reads and writes unlike RAID 5 which is a bit slower on writes due to the parity calculation (although it speeds reads). The more disks you have in array, the more chance of 2 disks failing at the same time. RAID 6 protects against this and gives about 88% of raw capacity. RAID 6 is similar to RAID 5 in terms of performance and is good for data warehousing. Re. RAID levels.

In terms of video edit data the RAID level you use won't have much impact on performance. For redundancy RAID5 with 3 drives can be superior to RAID1 with 2 drives, but it depends how you set it up. Ideally if you're really worried you would take a backup onto a separate drive or onto a DVD/Tape. Netgear have a pretty good selection of NAS devices which support from 2 to a number of drives.
