Now let’s compare the performance of the drive with its three different interfaces. First, we performed the test on a 32GB partition.

The FireWire800 interface is much better than the other two interfaces in NTFS (we mean the more important High-End Disk WinMark parameter in the first place). The FireWire400 interface in its turn is more efficient than USB 2.0.

There’s a tougher competition as concerns the second parameter, Business Disk WinMark. FireWire400 is a little better than FireWire800 here.

The drive performs overall faster as we switch to FAT32 and FireWire800 again has a much higher High Disk WinMark score than the other two interfaces while FireWire400 in its turn is better than USB 2.0.

As for the Business Disk WinMark parameter, FireWire400 is a little better than FireWire800, again.

This time we check the data-transfer rate on the entire capacity of the drive. The diagram is an illustration of different efficiency of the interfaces: FireWire800 is the best, followed by FireWire400. USB 2.0 is the least efficient interface of the three.

The last of WinBench 99 diagrams shows you the measured access time parameter. It is roughly the same with any interface and is considerably higher than the declared access time. This discrepancy must be due to the drive’s using a quiet mode of operation for its heads.
