Defragmenter - built-in or third-party?

Question

Windows

What do you think is better to use a defragmenter - built-in (for Windows 8.1) or third-party (for example, Defraggler)?

Answer 1

You don't have to use it at all.

Answer 2

emnip built-in defragmenter has such an algorithm of operation
1) does not combine fragments larger than 64 mb (really, why? for pieces of 64+ mb, the reading speed is already linear)
2) leaves free space after files of some extensions - margin for increasing the size
3) defragment if necessary a separate file - if it is in the list of prefetch services and superfetch adds them closer to the beginning if not closer to the end, leaving the middle of the disk free for writing
as a result, it works quickly the result is a solid four
other defragmenters work in such a way that the defragmentation process takes longer,
and often after them, the disk starts to fragment faster (they forget to leave room for expansion),
but in general it is necessary to correctly use the basket to delete the contents only when there is not enough space and before defragmentation, then there will be no "holes" in which you can write the file, and keep 20% of the disk free - then the OS will have a place where to allocate space for the entire file, as a result, defragmentation passes with a speed close to linear reading and consists in freeing up free space in the center of the disk.

Answer 3

look at the descriptions of the functions
standard function of the defragmenter: storing files in a continuous sequence of clusters, emnip, is performed by the defragmenter from MS with a bang.
If you need to put some files at the beginning of the disk, others, rarely used - at the end, then MSovsky does not know how, but third-party ones boast.
See what you need.

Answer 4

The defragmenter is needed for the HDD to quickly move the disk head.
One of the important functions is MFT defragmentation. Of the defragmenters I've tested, only Raxco PerfectDisk can do this. It can also defragment files while the computer is idle and do smart placement - smart file arrangement.
Built-in defragmentation has not been used since Windows XP. There is very little functionality.
