Data Compression
The DLT VS80 tape drive offers a formatted, native cartridge capacity of 40 GB
(80 GB assuming a 2:1 compression ratio) and a sustained user data transfer rate
of 3 MB/s (up to 6 MB/s with 2:1 compression).
Note: Capacity may vary based upon actual stored data. Data transfer rate can vary
depending on actual data.
The DLT VS80 tape drive ships from the factory with data compression enabled
for writing. In this mode, data is always compressed when writing to the tape, but
the drive is capable of reading both compressed and uncompressed tapes. For the
drive to write uncompressed data, the data compression setting must be changed
through the software. To change it, consult the backup application software
documentation for the data compression enabling and disabling procedure.
