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.

It’s the first time we test 1-terabyte HDDs with WinRAR. Surprisingly enough, the Hitachi 1000.B proves to be the best when creating the archive. Next goes the updated Caviar Black, Samsung F1 and, amazingly, the M2 version WD10EADS. The 7200RPM newcomers with high-density platters are no better than the rest of the HDDs. The unaligned WD10EARS does not fall too far behind because this task is mostly about reading.

The unaligned disk needs over eight minutes while the others unpack the archive in only one. Well, the WD10EARS is not really good even when aligned: it needs three times as much time as the others because the files are small. The rest of the HDDs split up into two groups: the leading group includes the Caviar Black drives, the two new models from Samsung (the F3 and the F2) and the old Hitachi 7K1000.B.
