After a year of balking at giving >some kind of replacement idea for RAID, still no answer. I'm going to disagree with both of you. For video work, with high-transfer rate, 1TB SATA drives selling for peanuts, there is little reason for using a RAID. A TB is more than enough to store 3 hours of uncompressed 24p 1920x1080 (HD) video. With storage virtualization/replication you can span multiple physical volumes to create larger virtual volumes. So there is no need to bother with creaky old RAID. For reliability, we are way past the point where hard drives are the weakest link. Just last week I was reviewing drive specs and noted MTBFs of 300,000 hours (that is 35 years of 24/7 operation). These days I'm seeing RAM and MoBos failing at about the same rate as hard drives. With MTBFs like that, the complexity of RAID reduces reliability. Nope, RAID is for the uninformed. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
