Wait, if I lose 17 disk drives, I think my data is the least of my problems. I'll just go buy a new server and start over.

17 disk drive failures? What is this, a Raid setup for the Death Star? I'm going with 5, keep it simple.

Psh, you both are way off. It's clearly 3. Why else would they give us 17 as an option? Gotta be a trick question.

Hold on, I think the answer is 7. Isn't that how erasure coding works? You can lose up to half the segments and still recover the data.

With 12 data segments and 5 coding segments, the maximum number of disk drive failures it can protect against should be 5. After all, that's the number of coding segments, right? Simple math.
