According to their site, the card is not actually RAID 1+0 (10), but rather 0+1. They still call it RAID 10, but it's not. They describe it as mirroring the stripes, not striping the mirrors. Capacity and performance are the same for both implementations, but there is a huge difference in fault tolerance and how a failure/rebuild affects the array.

I thought raid 0+1 was something they included in the textbooks as an example of what not to do, I didn't think anyone would actually go and implement it.
It would be so much better to use raid 5 - you would get almost double the capacity at about the same reliability, or better yet, two spindles (if you can still call it that) of raid 5 using 3+1 each
