I'd recommend explaining even a tiny bit what erasure coding is. I had to look it up as I didn't know the term. It's really cool, explain it yourself, why you're excited about it!
This is a really important property in situations where there can be big giant bursts of errors, because you can still reconstruct the data regardless. IIRC, CDs/DVDs/BDs all use two concatenated Reed Solomon (a type of erasure coding) coded symbols that are then interleaved with each other, which provides the disk protection against things like accidental scratches.
