By using the buil
t-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 “Media optimization” on page 17
for more information.

See “Archive mode unthread” on page 18 for more information.
Remember:
• All sustained data rates depend on the capabilities of the interconnect.
• Drive performance varies with media generation and drive interface (SAS/FC).
