G.G. and John,
Thanks for your posts. I'm glad I created this thread because I was pretty close to going the RAID 10 route. My goal is total data protection. I do not want to ever in the near future be in a position where I find myself rebuilding my RAID array from scratch a second time. This would be a total pain in the rear.
G.G. the way you explain RAID 6 has convinced me it's the way to go. I have 24 1TB hard drives but in reading through my Areca Controller user manual I learned this card also supports hot swop drives. If a drive falis, without any human intervention, this controller card will automatically rebuild the failed drive data to a hot swop drive. I am currently waiting for two additional 1TB Hard Drives and a SFF-8088 to SATA Fan Out cable. My plan is to assign two hot swop drives using the external 8088 port my Areca card has in the rear. This way I don't sacrifice any of my 24 drives as hot swop drives. I am looping the cable back into the case where my two hot swop drives are located.
Lastly, for 24 drives RAID 10 uses 12 for data and 12 for backup. What about RAID 6? Based on 24 drives, how much of the 24 TB of space will be available for data storage and how much for backup? I would appreciate hearing back from anyone with an answer to this question. THanks.
