I'm in the process of building a 100TB RAID 6 array to replace my multiple 10-12 TB standalone disks. I was originally looking at doing a 180TB array, but it's just too expensive.
Depends. There's a definite train of thought that JABOD is the bee's knees, and that arrays can fail, etc., etc. Yes, arrays can suffer multiple disk failures, and even RAID 6 can suffer a triple disk failure within the rebuild period.
It essentially comes down to a duality: easily expanded JABOD with risk of disk failure destroying data or the rigid RAID array that might suffer data failure, if you lose 3 disks within a couple of days. And you SHOULD have backups, in either case.
