How Much Data Can I Write To The Tape - HP N1200 - StorageWorks Network Storage Router Faq

How much data can I write to the tape?

The amount of data written that can be written to a tape is impacted by the
compression ratio of the data and the error rate performance of the
tape/drive combination. It may not be the same as the capacity marked on
the cartridge which assumes 2:1 compression ratio and reasonably good
error rate.
Use the Device Performance test to measure a specific tape/drive
combination.
Note - This test will take a long time and overwrite any data on the tape.
1. Install and run L&TT
2. Insert the tape in the appropriate drive.
3. Select the device and click Dev Perf on the toolbar.
4. Set parameters as shown – or choose a different compression ratio –
and start. Note the Test Size is set to Full Tape
5. See Drive Performance Results tab for results
