A Reed-Solomon inner-outer encoding scheme. B Relationship between log decoder error probability during RS decoding and DNA strand length, including the effects of symbol error rate (mutations, insertions, and deletion, Perror) and copy number. C Relationship between information density of a DNA storage system and the probability of symbol erasure (strand loss due to breakage) as a function of strand length. D Relationship between information density and strand length as a function of the probability of strand breakage. C and D assume a copy number of 1.
