Hi all, Im thinking of using a NAS RAID storage device for my audio. I want to choose a raid setup that will protect me against drive failure. The most appealing is RAID 5 considering i can take 4 drives, use 3 of them and the 4th is used to for the indexing and rebuilding of the data. However, a simple RAID 10 mirroring system is the safest bet, but i don't get the most out of the RAID system. My confusion is, How can one drive (6TB) successfully rebuild 3 other drives (18TB)? The math doesn't make sense. And if it does recreate the missing data with some type of stored index of data, how will it rebuild the files? It seems like it will most likely affect the sound quality of the files if it has to manually rebuild them and add 1's and 0's Any insight into this would be much appreciated.
After deciding that I probably do not need a NAS for my music library, I am planning to get a new external hard drive or two. That brings up the RAID or non-RAID question, so I want to make sure I am understanding this correctly. It seems like the only advantage of RAID (RAID 1, Drobo, etc.) for an external drive that will be used only to store my iTunes library would be storage capacity. Is that correct, or are there other benefits I'm forgetting? Since my music storage needs are nowhere close to 4TB (probably more like 1TB), it seems like I'd be better off skipping RAID for that drive. Assuming that RAID drives work well with Time Machine, I might consider one as a full system backup option at some point, but I probably don't need that much space now.
