So when I set up storage spaces, I wasn't really prepared for the performance gain/impact it have, the following speed test shows what storage spaces, in parity mode, is good at. I have not tested it in any other modes so can't talk about their performance here.
The drives underneath is 4 equal Seagate Baracuda ST3000M001, my storage spaces config looks as follows:
Finally, just to show why I want that server with 2TB memory:
