5 Gb to 50 Gb of contiguous data transferred
All other types of mount activity
1
By using the built-in data-compression capability of the tape drive, greater data rates than the native data transfer rate are achieved. However, the actual
throughput is a function of many components, such as the host system processor, disk data rate, block size, data compression ratio, SAS bus capabilities, and
system or application software.

Cartridge initialization time can vary. See

Archive mode unthread
Remember:
All sustained data rates depend on the capabilities of the interconnect.
Drive performance varies with media generation and drive interface (SAS/FC).
