We were comparing capabilities and features, and in that context I say that there is a substantial perfomance difference. I don't have figures or links at hand, but I have seen them.
We are not talking about what you or I need :-) I can't pay it, anyway...
Greg just said that the CPU time required for a simple 2-disk mirror is only minimal. Such unquantified statements do just not mean anything. If you're talking about a 6-disk raid 5 perhaps it is going to matter, you know? I just don't know. But I'm not going to look up data because just you are not doing it :p. You are the one making the statements, then back it up.
No, it doesn't work that way, I'm not going to prove anything. I investigated the issue a decade or two ago, I was satisfied, and that's it. If you want hard facts, you will have to search them yourself. I'm not going to dig out magazines on the basement and scan them ;-) But if you google "hardware raid versus software raid perfomance" you find hits. The first one is a paper from adaptec. Another one is a benchmark.
Guess what it is. Perhaps you already know it. What or which is the one ncurses menu-style blue-interface-with-white-lines application on Linux that is just awesome?
mc, pine, lynx, yast...
So I can just say that at present, I am at a loss of how to manage my raid. I barely know what to do in case of failure. Yes, SEARCH THE WEB.
If it is Linux software raid, there are some howtos at TLDP. - -- Cheers Carlos E. R.
