Defragmenting your hard drive can be goodor bad for the device depending on what kind of hard drive you'reusing. Defragmentation can improve data access performancefor HDDs that store information on disk platters, whereas itcan cause SSDs that use flash memory to wear outfaster.
The larger the hard drive, the longer it willtake. So, a Celeron with 1gb of memory and a 500gb harddrive that's has not been defragged in a long timecould take 10 hours or more. The high end hardware takes anhour to 90 minutes on 500gb drive. Run the disk cleanup toolfirst, then the defrag.
When You Should (and Shouldn't) Defragment.Fragmentation doesn't cause your computer to slow down asmuch as it used to—at least not until it's veryfragmented—but the simple answer is yes, you should stilldefragment your computer. However, yourcomputer may already do it automatically.
Regularly running the Disk Defragmenter utilityimproves system performance. When the computer saves files,it fragments the files into pieces and saves the pieces in variouslocations on the hard drive. As a result, Windows accesses filesfaster, and new files are less likely to befragmented.
Optimize Drives in Windows 8, previously calledDisk Defragmenter, helps to optimize the differenttypes of drives that PCs use today. No matter which type ofdrive your PC uses, Windows automatically chooses theoptimization that's right for yourdrive.

Normally, a defrag operation will notcause data loss. Unfortunately, if there's a pre-existingproblem, a defrag could bring data loss to thesurface.
This would cause your computer to run slow downsince it takes longer to read a fragmented file compared to acontiguous one. To speed up computer's performance, youshould defrag your hard drive all the time.Defragging is a process that reduces the amount offragmentation in file systems.
Android devices should not bedefragmented. Defragmenting an Android device willnot lead to any performance gains, as flash memory is not affectedby fragmentation. If your Android phone or tablet isperforming poorly, there are several steps you can take totry to increase performance.
That's contiguous from a disk drive point of view, sothey can be loaded quicker. As an aside, never run defrag onan SSD: it will not improve matters at all but will waste preciouswrite cycles of your SSD, resulting in it wearing out sooner.Because defragging only re-organises files, it will notfree up disk space.
Anytime your disk is more than 10% fragmented, youshould defragment it. Also, if your computer is running slow,you should consider doing a defrag as thefragmentation may be causing your PC to run moreslowly.
By default, Optimize Drives, previously called DiskDefragmenter, runs automatically on a weekly scheduleat the time set in automatic maintenance. But you can alsooptimize drives on your PC manually. This tutorial will show youhow to manually optimize drives to defrag a HDD or TRIM aSSD in Windows 10.
Defragging rearranges the layout offiles on your hard disk for faster access. Specifically when(or even if) you need to do it at all is evolving.“Defragging” is short for“de-fragmenting” and it's a process runon most hard drives to help make accessing the fileson that disk faster.
How to Defragment Your Computer Hard Drive
- Choose Start→Control Panel→System and Security. TheAdministrative Tools window appears.
- Click Defragment Your Hard Drive. The Disk Defragmenter dialogbox appears.
- Click the Analyze Disk button.
- When the analysis is complete, click the Defragment Diskbutton.
- Click Close.
The larger the hard drive, the longer it willtake. So, a Celeron with 1gb of memory and a 500gb harddrive that's has not been defragged in a long timecould take 10 hours or more. The high end hardwaretakes an hour to 90 minutes on 500gb drive. Run the diskcleanup tool first, then the defrag.
Although with modern defragmenters like Auslogics DiskDefrag you can continue using your PC whiledefragmentation is running, it is still a good ideato limit PC use or run the defrag whenyou are away from your computer, if you wantto get the best results.
When it says 0 percent fragmented it meansthat there are no chopped files and folders on that disk. So, yourcomputer runs smoothly.
Defragment your hard disk for a fasterPC.
Note: Do not use defragmentation on SSD disks.If you've cleaned up space on your drive, congratulations:this alone should make your computer faster. Thismakes searching for files and accessing them muchquicker, so your PC will feel much moreresponsive.So, no, you should not defrag anSSD. And performing one will actually reduce the life ofyour drive. The TRIM command is supported by the latest SSDsand will optimize the hard drive so that it reduces the number ofwrites/deletions and therefore extends the life of your SSDsignificantly.
It can take up to 10 hours, over 30passes on low end processors. I suggest a disk cleanupbefore starting a defrag, and also consider if it isreally necessary.
You can safely stop DiskDefragmenter, so long as you do it by clicking theStop button, and not by killing it with Task Manager orotherwise "pulling the plug." Disk Defragmenter will simplycomplete the block move it is currently performing, and stopthe defragmentation.
By default, Windows will defrag all of the harddrives connected to your machine once a week. In fact, if you lookin the “Microsoft” branch of the Windows TaskScheduler (in Start, All Programs, Administrative Tools), you'llsee that there's a scheduled task for exactly that purpose: 99% ofthe time, that's plenty.
How to use Optimize Drives on Windows 10
- Open Start type Defragment and Optimize Drives and pressEnter.
- Select the hard drive you want to optimize and clickAnalyze.
- If the files stored on your PC's hard drive are scatteredeveryone and defragmentation is needed, then click the Optimizebutton.
