RAID for NAS

[sbecompany]

For a graphics rendering farm I was planning on using a NAS or fileserver. What kind of RAID system could be used? I was thinking perhaps using one set of drives set up to run at high speed and another to act as a backup raid.

Considering using RAID1, RAID5, RAID6, RAID10 etc to provide data redundancy.

For periodic backup only, a set of drives configured in RAID 1 would provide nearly absolute security of data. To run a single set of drives without periodic backup, RAID 1 with fast drives would provide some speed + redundancy. RAID 10 would yield a performance boost over RAID 1, though at the price of double the cost of RAID 1. RAID 5 is a compromise in between the two in cost and performance. If redundancy is a necessity and cost is an important consideration, RAID 1 is the best value – If performance is more important than cost then you could consider 6 or 8 drive RAID 10 setups. Tom’s has some benchmarks that may help in deciding on cost vs performance.

The answer lies in the amount of data you need to back up. That's how we hardware guys make these kinds of recommendations. What you need for a a 1/2 dozen node network and what you need for 3000 nodes in an enterprise environment are very different things.
