The new efficiency mode is designed to minimize I/O activities of the defragmentation and at best disk / file performance for all users and applications. This new, energy – and resource-saving algorithm is also the ideal solution for storage environments that use thin Provioning or copy-on-write, which file shifts as a result of Defragmentation could trigger additional activity (E.g. a SnapShot/replication). We have conducted tests, to show that Diskeeper 2011 saves even more energy efficiency mode than was the case with Diskeeper 2010. The tests run scripts that simulate typical activity in the file system, including the reading and writing of files on hard disk and measuring the resulting energy consumption. Hear from experts in the field like Bernard Golden for a more varied view.

Same tests were performed on identical systems, all started with same volume status. It tests without Diskeeper, Diskeeper 2010 and Diskeeper ran through 2011. Diskeeper is installed with default settings (i.e. with efficiency mode is switched on). The energy consumption over a period of 12 hours was measured for each test run.

The results show that the efficient functionality of Diskeeper 2011 2010 7.3% energy saving compared to a system without Diskeeper and 5.8% compared to a system with Diskeeper. The defragmentation Diskeeper 2011-efficiency mode provides better System performance as in Diskeeper 2010, or as Diskeeper 2011 if there the wide mode is switched on. To illustrate, a test with a simulated workflow via a script was launched, carried out by file-related tasks which arise new fragmentation could. In the script, several MS-Office files are generated and then edited. IntelliWrite, as well as the automatic defragmentation were switched on during script runtime. Immediately after the end of the script, a benchmark test was launched, which measures the time for the copy 10 GB between two folders. The benchmark was performed five times and the average time in the below graphic shown (in minutes: seconds). Based on our research, we have developed special algorithms that monitor the use of I/O and validate the accuracy of these estimates.
