Next goes our homemade test of defragmentation speed. We created a very defragmented file system on a 32GB partition of a disk by loading it with music, video, games and applications. Then we saved a per-sector copy of the disk and now copy it to the disk we want to test. Next we run a script that evokes the integrated defragmenter of Windows 7 and marks the time of the beginning and end of the defragmentation process. For more information about this test, you can refer to this article.

We must remind you that defragmentation is useless and even harmless for solid state drives due to their operation principles. However, we use this test as it allows to benchmark their performance at a rather peculiar load that involves both reading and writing of small data blocks.

Our test image is exactly 32 gigabytes large, so we cannot benchmark the Extreme X32 model in this and next tests.

And once again the P128 performs brilliantly, beating the F120, while the P256 takes three times as long to complete the task! We just can’t explain this. The rest of the SSDs are more predictable: the Extreme series are ranked up according to their capacity. The Reactor and Nova are somewhat slower than the others.

Performance in WinRAR

Now we are going to show you one more interesting test in which we use WinRAR version 3.91 to compress and then uncompress a 1.13GB folder with 8118 files in 671 subfolders. The files are documents and images in various formats. These operations are done on the tested drive. This test depends heavily on CPU performance, but the storage device affects its speed, too.

The P128 is again in the lead while the Reactor and Nova take second and third places, rather to our surprise. The Extreme series are now at the bottom of the diagram, retaining their respective standings. The P256 is slow, too.

One more win for the P128 that shares top place with the Force. The other Performance series product is last, having spent half as much time as the others to unpack the archive.
