RAID 96

Looking through the new features of my QNAP 3.6 firmware I see SYMFORM cloud backup. I take a look at their offering and I see this RAID 96. I read the details and it looks like RAID5 at a 1MB block size. Their claim to only need 64 of 96 blocks to recover 64MB of data is a bit misleading. You still need the right 2 of 3 blocks, not just any 64 of 96 to get your data back or am I wrong?

Hard to say, if they used raid5 across 2 datablocks to create a 3rd block, yes, if they did something different, like par, then no. But I bet they just did a raid5 xor.
