7+ years since the OP got an update. Is it still current? I tried to get RAID 10/1+0/0+1 whatever one wishes to call it. I choked. I had 8 WD Cav Black 1TB drives gathering dust, and picked-up a 2720SGL card cheap. Thought I'd use them all, cheap WIN. Best speeds, 4TB is PLENTY, and total cost is peanuts. I believe the theory is perfectly fine. RAID 10 scales. I created the array in the Rocketraid BIOS. Windows never saw it properly. By memory, it only saw 2TB partition + 3TB unaccessble (in ANY way) or something messed-up like that. Copied stuff on there from an SSD. Speeds were <150MB/s. Eventually restarted the PC... Array was never seen again. That was 10+ months ago. RAID and I SERIOUSLY do not get along.
