Performance in FC-Test
For this test two 64GB partitions are created on the drive and formatted in NTFS. A file-set is then created, read from the drive, copied within the same partition and copied into another partition. The time taken to perform these operations is measured and the speed of the drive is calculated. The Windows and Programs file-sets consist of a large number of small files whereas the other three patterns (ISO, MP3, and Install) include a few large files each.
You should be aware that the copying test not only indicates the speed of copying within the same HDD but is also indicative of the latter’s behavior under complex load. In fact, the HDD is processing two data threads then, one for reading and another for writing.
This test produces too much data, so we will only discuss the results obtained in the Install, ISO and Programs file-sets.
Each drive shows its peculiar character when creating files. The new drives from Seagate, especially the Constellation ES, prefer to write large files whereas the Hitachi and the Toshiba are faster with small files. Take note that the Hitachi is even ahead of the 3.5-inch HDD, despite the latter’s higher sequential speeds, in the Windows and Programs patterns that contain small files. This is the effect of firmware optimizations.
It’s somewhat different at reading: the HDDs are closer to each other, although we can see that the Constellation ES is very good (and the 7200.4 is inexplicably poor) with large files whereas the Momentus XT is better than the others at reading small files.
When copying files, the Constellation ES is ahead with large files while the Momentus XT, with small ones.
