- oofabz 5y agoAre 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?
- sliken 5y agoGenerally blocks. So backblaze takes 17 blocks of input, and generates 20 blocks out output. Then recoveries work if 17 or more blocks are recovered.
