I answered your questions from your first post, if that is sufficient for you then I fail to understand the relevance of your post above. As far as I am concerned I have no problem if a user wants to run a raid system it's all down to personal choice.
We're not getting on here are we. Likewise, I fail to understand the relevance of your post, since your answers to my first post is simply "RAID is no good" and now I ask what is your suggested alternative, you don't answer that and merely state you already answered my initial questions and sneeringly denigrate my follow-up request for some additional information.
I'm sure geaves you are very knowledgeable, but so am I. Just not in the same field obviously. I came here to ask reasonable questions and hoped to receive reasonable and helpful replies and I have to say, neither have been forthcoming.
I will look further into unionfs and Snapraid that I had previously considered prior to asking here about actual RAID. Ultimately, I will make my own decision as you say, but I will obviously need to conduct my research elsewhere.
Good day to you all.
