That means even if you have tons of fragmented files, your computer won't slow down-and defragmentation isn't necessary. SSDs are much faster than hard drives, and don't have any moving parts, so your computer can read blocks of data just as fast from one spot on the NAND as from another. You should note that everything above only applies to traditional, spinning hard drives-not solid-state drives (SSDs), which are becoming more and more common. Viruses, Malware, or Spyware: What's More Dangerous? By default, it should run once a week, but if it looks like it hasn't run in a while, you may want to select the drive and click the "Optimize" button to run it manually. If everything's running okay, your HDDs should read "OK (0% fragmented)," and you can see when the drive was last defragged. Next to each drive, you should see its Current Status. However, if you want to check the schedule and make sure it's running properly, hit the Start button and type in "defrag." Click the "Defragment and Optimize Drives" option, and you'll be greeted with the optimization schedule, which lists all the drives in your computer-HDDs and SSDs alike. So there's a good chance you don't actually have to do anything!
Here's the good news: unlike the old days of Windows XP, which required you to manually defrag your hard drive once in a while, Windows 7, 8, and 10 defrags your computer automatically on a schedule. You can see a visual representation of this in the GIF above, from Wikimedia user XZise. That means the drive's head has to navigate to multiple places in order to read the file, thus slowing things down.ĭefragmenting your drive reassembles those files and combines your free space back into one block, making reading and writing faster. If you delete some data, the drive will go back and fill those blocks when you write new data-sometimes leading to files getting split apart and stored on two (or more) different sections of the platter. Traditional hard drives (sometimes known as HDDs) use spinning platters to store data in sequential "blocks" across each platter. Here's how it works, and what you need to know. Defragmenting (or "defragging") is one of the most commonly recommended tasks in this area, alongside uninstalling programs, checking your PC's memory, and running a virus scan.
