My point of view was (I think) more in line with the OP's title of this thread, being a home server. I have only 1 home server. I suspect he does also as it's his first time doing RAID, as it was for me. <SNIP> >> >> As I said I don't using an initrd.

Well again, as I don't use an initrd or even know what it is I have a lot of learning to do in that area. I've just never bothered. I've run Linux as a desktop system for about 13 or 14 years now. Maybe some other distros used initrd by default but Gentoo, which I've run since about 2000 or so, doesn't require it. For desktop systems based on lowest common denominator PC hardware it's never seemed to provide any real advantage. Certainly it does for bigger servers where you guys buy fancy hard drive controllers and the like. But again, I'm talking about something I don't use and don't know much about so I have a pretty limited perspective. Getting started with RAID is the first time I've seen the value for my machines, and then only for the boot partition. Thanks!
