And now let's take a look at the HDD performance in the same tests, but with the partitions formatted for NTFS file system.

The transition to NTFS file system doesn't change anything during files creation. The newcomer is again ahead, although the advantage is not too great.

Passport 250GB remains an indisputable leader during file reading.

During files copying within the same partition and from one partition to another, the situation also repeats. Passport 250GB is always ahead of the younger competitor.

Conclusion

The new Western Digital solution turned out an indisputable success. It is not only the today's largest external solution on 2.5" hard disk drive, but it proves excellent in all work modes tested. I would specifically like to stress great performance of Passport 250GB during multi-threaded work as well as efficient work with lazy write algorithms that the drive owes to the new IDE-USB adapter. Unfortunately, USB interface sometimes becomes a limiting factor and prevents the drive from revealing everything it is capable of.

As for the encountered drawbacks, I would like to mention the absence of additional power supply, which is typical for the entire Passport series, as well as easily scratchable surface of the casing.
