5  Cartridge Fill Times 5.1  Introduction This section shows the performance improvements in cartridge fill times for the IBM Ultrium 2 when compared with the IBM Ultrium 1.   The tests are executed using a benchmarking tool that writes fixed blocks from memory.  For this test the compression engine of the drive is turned off.   5.2  Cartridge Fill Times Performance Summary The following summarizes the performance results with the IBM Ultrium 2 relative to the IBM Ultrium 1.  Refer to Section 5.4 for detailed results. The IBM Ultrium 2 demonstrates the following performance improvements when compared to the IBM Ultrium 1.   Sustained transfer rate improves 126% to 122.9 GB/hr Time to fill an Ultrium 2 cartridge is 12% less at 1 hour 44 minutes Sustained transfer rate for Ultrium 1 cartridge improves 32% to 71.9 GB/hr Time to fill an Ultrium 1 cartridge decreases 24% to 1 hour 29 minutes 5.3  Test Environment The description of the test environment is as follows.
