SAMchain performance. a Before inserting SAM data to a SAMchain, we remove the sequence and quality strings. In plain text, we measured the storage gain by removing these fields. b The total network storage required for a SAMchain storing ~ 10 million reads. c Total time to insert data to SAMchain as a function of number of reads when a different number of CPUs are used. d Storage (compared to a SAM file), time (for a single CPU), and memory used to build a SAMchain
