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 three 30GB models in this and next tests.
The SSDs pass this test with close results and are ranked up according to their capacity with only one exception: the Vertex 2 leaves the others behind and wins the test.
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 results are close in this test, too. The SSDs do not even split into groups according to their capacity. However, the Vertex 2 manages to win the test of unzipping the archive. Considering the minor role of the storage device in this application, the advantage of 6 seconds looks impressive.
