Performance in FC-Test

For this test two 32GB partitions are created on the drive and formatted in NTFS and then in FAT32. 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.

We’d like to note that the copying test is indicative of the drive’s behavior under complex load. In fact, the drive is working with two threads (one for reading and one for writing) when copying files.

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 achieved in NTFS in the Install, ISO and Programs file-sets. You can use the link below to view full results:

Western Digital’s drives are ahead when writing files irrespective of the specific file-set. The Hitachi is good with large ISO files but falls behind its opponents when processing the small files of the Programs pattern, although Hitachi’s older HDDs used to behave in the opposite manner. We wonder if this is due to our transition to the ICH7 controller or to a dramatic overhaul of Hitachi’s firmware.

When reading large files, the HDDs are ranked according to their results in the IOMeter: Sequential Read test with one exception: the Seagate Barracuda XT on the Marvell 9123 falls behind its counterpart on the ICH7 controller for some reason. The same gap, even though smaller, can be seen with the other file-sets.

Copying is very similar to writing: Western Digital’s drives are ahead (you can easily see how superior their firmware is as even the Caviar Green competes successfully with the HDDs from other makers) and the Hitachi 7K2000 is very fast on large files, without showing anything exceptional on small files.
