  1. …implements Reed-Solomon error correcting codes and there are many recent implementations of those: https://github.com/klauspost/reedsolomon .

  2. …Go. It allows you to set the number of data shards and parity shards, it's pretty fast. It's at https://github.com/klauspost/reedsolomon Seems like a pretty common solution, I suspect there's other libraries for popular language/platforms.

  4. …storage package. It runs approximately as fast (~1GB) because the hot paths are written in asm: https://github.com/klauspost/reedsolomon Erasure codes are pretty magical.

  5. Klaus Post did an implementation of this in Go using with the relevant bits in SSE3 assembler: https://github.com/klauspost/reedsolomon He references the paper in the amd64 code blob: https://github.com/klauspost/reedsolomon/blob/master/gal…

  6. Anyone know of a comparison of similar tools. I've tinkered with this one: https://github.com/klauspost/reedsolomon/ I believe it's compatible with the Java implementation used by Backblaze and others.
