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 console version of the Perfect Disk 8.0 defragmenter and marks the time of the beginning and end of the defragmentation process. We run this test with AHCI enabled. For more information about it, you can refer to this article.
We’ve got interesting results here. First place goes to the Samsung F3 which is followed closely by the single-platter WD Blue V1. Next go the other 7200RPM drives from WD. Three HDDs should be criticized: the Seagate LP and Seagate 7200.11 spend too much time for this task while the Hitachi 7K1000.C is downright sluggish.
Performance in WinRAR
Now we are going to show you one more interesting test in which we use WinRAR version 3.8 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.
There are three groups of HDDs at archiving. The Blue M9 and A7 from Western Digital, the Seagate LP and the Hitachi 7K1000.C are, rather surprisingly, in the lead. The Samsung F2 and Seagate 7200.11 are the slowest drives here, rather expectedly.
The HDDs differ a lot in this test. The worst drive needs 50% more time to complete the task than the winner. One loser is predictable: it is the Hitachi 7K1000.C with faulty firmware. The other loser is the WD Green with 32MB cache. The Samsung F3 and the WD Blue M9 deserve our applause for their performance in this test.
