Try using an app that has been updated within the last 2+ years. The one you decided on was last updated in February of 2012. Abandonware is not usually going to give the best results.

Benchmarks are arbitrary and have no real meaning. The one you went with doesn't really say what is being tested. Your results seem to be related to SD card performance. Try a more reputable app such as Antutu or similar if you simply must delve into benchmarking.
