Linear read/write times and storage space requirements for different file formats on 22 file fragments over 10 repeats. Linear read and write speeds are measured in 10⁶ (m/z, abundance) pairs/s; storage space is measured in MB/10⁶ (m/z, abundance) pairs. All mz5, mzXML, and mzML measurements are shown as circles, diamonds, and triangles, respectively. a, the mz5 format exhibits a 2.28-fold increase in reading speed compared with mzXML and a 3.65-fold increase compared with mzML. b, mz5 roughly halves the storage space requirements when compared with mzXML (53%) and mzML (55%). c, space requirements for mzXML, mzML, mzML with file level compression (gzip), and mz5 relative to Thermo raw, Bruker yep, and ABSciex wiff format (dashed line). The mz5 format minimizes storage requirements while providing fast raw data I/O.
