The comments to the write speed diagram are true here as well. Copying files within the same disk partition doesn’t reveal any advantages from the 32MB buffer, and the Deskstar 7K1000 is also slightly slower than the 7K500 in the ISO file-set.

The two most recent generations of Deskstar HDDs exhibit the old dislike of copying large files, but in a lesser degree.

Copying small files is even more impressive than writing them: the Deskstar T7K250 is two times as fast as its predecessors while the newest 7K1000 is three times as fast!

The newest model has its triumph when copying files into another disk partition: it has at last broken free from the pursuing Deskstar T7K500.

There is no doubt the 32 megabytes of buffer memory help a lot when copying data at long distances. The buffer allows to move the heads less thus increasing their efficiency. The new HDD is especially good with the MP3 file-set.

We create two 32GB partitions for this test, which is less than 10% of the total capacity of the 1000GB disk. If the starting point were farther away from the destination point, the Deskstar 7K1000 would have an even bigger advantage over its opponents.
