* The compression rates shown assume an industry standard 2:1

compression ratio. Actual compression ratios achieved depend on

the redundancy of data files being recorded. For non-compressible

(expanding) data, this results in a reduction in capacity and

transfer rate for the data. Fully random data is the worst case for

compressibility.

** The SCSI bus limits burst speeds, not the design of SDLT 600 tape

drive or Super DLTtape II media.

Note: Cable lengths and cable type may limit attainable transfer rate;
