Thank you for that succinct and informative set of instructions. I shall now go off and read about the various things that you have cautioned me on and learn some more. It looks like I want to know more before starting down this road and that I should set aside some time to do this properly.
I worked for DEC (Digital Equipment Corporation) from 1986 to 2000 and managed VMS, OSF/1, ULTRIX and Windows NT systems for years, singly, in clusters and clumped as functional blocks, PDP, VAX, MIPS and Alpha. It's been some time since I was building RAID in various and sundry ways, but having done it before, I anticipate that past knowledge and experience with your guidance will turn out to be successful.
My neighbor uses SSD drives, so far he has burned out (wore down) three drives, and each time it was a sudden failure and I could hear the foul language from across the street. Ideally, a fast hard drive in RAID 1 with an SSD would be the cats meow, after all that was the principle of things at one point, different vendors devices mixed together to account for similar lifespan bathtub curves on different products.
Again, many thanks and when finished I will make another entyr here.
