* 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.

Head Life and MTBF

The projected mean time between failures (MTBF) for the overall SDLT 600 tape drive system is
250,000 hours, not including the heads. Head life is a minimum of 30,000 tape motion hours and an
average of 50,000 media motion hours.

shows the maximum sustained (and burst) data transfer rates for the SDLT 600 tape drive.
: Cable lengths and cable type may limit attainable transfer rate; for details,
refer to: SDLT 600 Design and Integration Guide (81-81196-01).
: The manufacturer does not warrant that predicted MTBF is representative
of any particular unit installed for customer use. Actual figures vary from
unit to unit.
