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.

Like in the previous tests, the WD10EARS is tested twice: with its partitions aligned and not aligned.

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:

Well, the Samsung F3 is ahead at writing irrespective of the file-set. It is followed by Western Digital’s Caviar Black drives that only give way to the Hitachi 7K1000.B in the ISO pattern. Interestingly, the newer and higher-density Hitachi is slower with each file-set, especially with small files. So, the firmware of the 7K1000.C is not really good after all.

As for WD’s power-efficient drives, the M2 version WD10EADS is ahead of the P8 whereas the aligned WD10EARS is good at processing large files, worse in the Install pattern and downright slow with the small files of the Programs pattern. But if you don’t align it, it will be very poor at writing whatever files you have to offer.

There is nothing interesting at reading. The standings are exactly as we might expect: the Samsung F3 and the Hitachi 7K1000.C are in the lead thanks to their high-density platters and 7200RPM spindle speed. They are followed by the Caviar Black series which are slightly faster than the other 3-platter products. And the power-efficient models go next. Take note that the WD10EARS is again no different from same-class drives at any loads when it comes to reading.

The Samsung F3 is unrivalled at copying files. The two Caviar Black drives take the other places on the podium, being a little faster than their pursuers. The Hitachi 7K1000.C shows an interesting behavior. It is good at copying large files but slow with small files. The WD10EARS has a hard time due to its emulation of 512 sectors. The aligned disk is as fast as its opponents with large files but slows down with small ones. The same goes for the unaligned disk, but it is always slower.
