We're not kidding about replacing, either - the program will turn off your usual defragmenter and install other programs if you don't uncheck those options during install, so be careful. This program tries to replace Windows' default defragmentation widget by being more advanced and offering more style, features, and customizations. Still, it makes up for that pestering with performance that rivals most defrag programs for Windows. It throws recommendations for other programs at you at every turn. The difference comes with the ability of the program to work out where best to move the data.įile location optimisation means the files are placed in an order such as to speed the loading of files.Smart Defrag 3 hits all the notes you'd expect from a defragger, but it is too aggressive in terms of advertising. I was referring to the method used to move data, they all use the Windows API. A defragmenter that just puts the files in order therefore does not facilitate great drive performance, however it still may lead to a 0 percent fragmented drive Also the beginning of a rotational drive is faster than the end, since mechanical HDD's work from the outside in (opposite to an optical drive which is inside out).įile location optimisation means the files are placed in an order such as to speed the loading of files. How can it be terrible you may ask? well, if the files that are required to be loaded are all over the place, the drive has to spin and the heads move more to read the next files data. You could literally have a perfectly defragmented drive for both files and free space, and the performance could be absolutely terrible! Free space fragmentation and file fragmentation are the main ones you see on the screen when defragging. There are different kinds of 'fragmentation'. File location optimisation has nothing to do with how fragmented the drives files are. Its a good thing that after defragging with one program another one said it wasn't fragmented. The difference comes with the ability of the program to work out where best to move the data. Of course you could always use the boot time defrag of one and the optimisation of another, such as using Speed Defrag just for the offline part and Auslogics free for the actual Windows based defragmenting.Ĭlick to expand.I was referring to the method used to move data, they all use the Windows API. Perfectdisk (version 12.5 is the latest) Auslogics Free (some limited functionality) I have found the best defragmenters, in terms of performance are: I won't knock the defragmenters that are like this. I have found some defragmenters do actually make the computer slower. If using a simply placement algorithm (like consolidate free space) then it will probably be a very quick process after already being done. If you defrag for file placement optimisation, you will find that each defragmenter will actually defrag again even if the drive is already done with another. There is a difference between different defragmenters. The difference comes in the algorithms determining placement of files etc. All defragmenters use the Windows Defrag API (or whatever they call it).
