Disregard my last statement. I did a test with HDTune 4.0 and the outer-ring is indeed the fastest overall, for seek, read and write times.
The interesting thing is that the first 40GB of my hard drive (which is what I have it short stroked to) has an access time of 4.5MS, where across the whole drive is 7.1MS. That's a pretty signifcant difference.
Fragmentation is just a file split across the disk, if the file is defragmented but at the end of the disk, it will still be accessed much slower.
Filesystems like EXT4 might
allocate files so that the files do not get fragmented until the drive is about 90% full, but they still have free space fragmentation and the order of files is still suboptimal.
Jeron has pointed out many times that MyDefrag is about more than just defragmentation. And that the only impact to disk performance is not just due to file fragmentation.
No offense, cheese, but that second article you posted is just terrible! Especially since it only talks about large files and not, let's say, <50MB files that are usually accessed more often. Although someone with 2GB or more of memory will have smaller files be placed into the page cache
anyway, they will still have to be the read from the disk the first time they are accessed each session (each usage without an OS reboot).
Has anyone read the comments on the first article posted? There are claims that fragmentation can help performance or defragmenting files on Linux filesystems can degrade performance. Unless the defragmentation process moves them farther from the beginning of the disk, where is the sense in such claims?
I agree with the original post, the word of MyDefrag really does need to be spread. I recently tried out the "SMARTPlacement" feature in a commercial defragmenter named PerfectDisk. I analyzed what it did to my disk and it did this:
Moved all files in WinSXS to the BEGINNING of my disk, along with a bunch of other spacehogs.
Small files were farthest
from the beginning of the disk, and had tons of free space gaps inbetween them.
I think everyone can realize what is wrong with the above.
MyDefrag is the only defragmentation program I'll ever use
