Mission "Defragmentation"

post #1 of 26

In this article we’ll discuss if defragmentation can be used as a performance test for hard disk drives. We will also see how the time it takes to perform a defragmentation procedure depends on the Native Command Queuing technology support. 16 hard disk drives participated in our test session.

Um... off-topic. Do you still have to defragment your hard drives in vista?

Yeah, but it depends how much they are defragmented. This isn't really a benchmark as some drives may be more fragmented than others, no matter what you have on them, how long the data's been there etc.

We used GetSmart tool to transfer this partition sector by sector to the tested HDDs. Thus, we made sure the data was absolutely identical on each HDD because the per-sector transfer maintained the original structure of files within the partition.
They are exactly the same data on every hard drive...

Yeah, the testing was identical across all the hard drives. It's strange that NCQ doesn't have any effect on an application that it was in all honesty designed to make faster :\\

That's true, but OS X usually doesn't need defragmenting, because it doesn't fragment your data, and uses more of the disk space instead of trying to fit everything in the empty spaces
