The manufacturer strives to operate BRC transfer rate at 100% of
native read transfer rate, but guarantees 80%.
** Transfer rates shown are nominal based on 80% of actual native
read transfer rate of uncompressed data.

SDLT 600 tape drive will eject a data cartridge written in DLT
formats other than DLT VS160.
