SRA - total filesize
Accumulated SRA and fastq filesize in petabytes (PB) by year. DDBJ Sequence Read Archive (DRA) stores sequencing data files (3.5 PB in total) in the form of SRA (2.3 PB) and fastq files (1.2 PB). Sequencing data are exchanged with EBI/NCBI in the binary SRA file format and the fastq files are generated from the SRA files at DRA. Total size of fastq is less than that of SRA, because fastq generation process is delayed.
