Now let’s check the performance of the drive when it is formatted in FAT32.

The first diagram shows you the speed of creating (writing) files. The FireWire800 interface triumphs here, again. The drive shows its highest speed when connected through it. The other two interfaces are considerably slower, and FireWire400 is somewhat better than USB 2.0.

The drive’s performance varies depending on the interface much in the file reading test, too. When attached via FireWire400, it is much faster than itself working via the other two interfaces. We can also see that FireWire400 is preferable to USB 2.0 in all the patterns.

This diagram has nothing new to say to us: FireWire800 is superior to both its opponents in the copy near subtest. The gap between FireWire400 and USB 2.0 is smaller.

The last test – copying files from one partition to another – produces the same picture. That is, the FireWire800 interface ensures the highest speed in all the patterns, while FireWire400 in its turn is better than USB 2.0.
