Aside from the defragmenting, we also used the optimization feature of the defragmenter, if available.In real time, you will not really feel the difference of 0.5s, 0.8s, even 0.1s so we decided to round down the decimals. We rounded down the decimals of time in seconds.We included the “Before” defragmenting on the ranking, which means “Before” will also get points.In case of tie, all the tied defragmenter will have the same point. We give 8 points for the best and deduct 1 point for each succeeding defragmenter. We assigned points for each disk defragmenter to determine the best and worst performer for each test.Rerun step 5-8 using the next disk defragmenter.This serves as “Disk Defragmenter #N” results. Restore the image file of the system drive.This serves as our “Before” defragmenting results. Create a disk image of the system drive.Copy all the files that will be use for testing and running the benchmark.Install all the necessary software, drivers, and all the disk defragmenter tools.The following is the sequence we followed to do the tests for each disk defragmenter. Microsoft Windows 7 圆4 with Service Pack 1 All the applications and files used for testing are all in this drive. The 55 GB System Drive serves also as our test drive. nVidia GeForce 9600GT 512MB DDR3, Forceware 306.97.Seagate 500GB hard disk, 55 GB System Drive.Modern solid state drives use a completely different technology to store data and never have to be defragmented. Remember that disk defragmenters only work with conventional, mechanical hard drives.
