    1 Compressed values use a nominal 2:1 compression ratio. Actual compression ratios achieved depend on the redundancy of data files being recorded.
    2 Performance may vary when the tape drive reads data previously written to the DLT VS80 and DLT1 formatted data cartridges. Performance depends on the quality of the data cartridge you are reading, not the DLT-V4 tape drive.
