Defragmentation

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 will run this test with AHCI enabled. For more information about it, you can refer to this article.

3.5-inch SAS drives are inferior to ordinary desktop HDDs in this test, yet we had not expected such poor results. The fastest drive here, the Fujitsu, takes almost 45 minutes to do the defragmentation. The two losers are especially impressive, though. The Hitachi C10K147 and Seagate 10K.1 spend two hours for this task! Take note that the spindle speed and recording density are not decisive factors in this test.

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.

The HDDs are all good in the archiving test. The difference between the best and worst model is a mere 21 seconds. The Fujitsu and the Hitachi C10K300 look better than the others, again.

The results are not so uniform when the HDDs unpack the archive. There are two obvious losers: the Seagate 10K.1 and the Hitachi C10K147. Surprisingly, the Seagate 15K.1 takes first place. At the end of our test program there is one more test where that model can win.
