Are the numbers the size in bits? If so, those are very small blocks. It seems like you would get more effective redundancy with larger blocks. Does Reed-Solomon scale so poorly that only tiny blocks are computationally feasible?

Generally blocks. So backblaze takes 17 blocks of input, and generates 20 blocks out output. Then recoveries work if 17 or more blocks are recovered.
