In fact, it could be damaging SSDs have a limited number of write cycles they can withstand. With no moving parts, there is little use in defragmenting your SSD. By storing files on NAND flash chips rather than spinning magnetic platters, data is able to be accessed at a fraction of the speed. SSDs are far faster than HDDs, owing to their lack of moving parts. If you’re using an older Windows operating system, you can manually defrag your hard drive by right-clicking on your local drive, pressing Properties, then Defragment Now under the Tools tab an easier solution would be to upgrade to a newer OS.īut do solid-state drives (SSDs) need defragmenting? The short answer is no. Beginning with Windows 7, PCs actually defrag your hard drive automatically, so you don’t have to concern yourself with it. If you imagine a hard drive partition that has had data written to it and subsequently deleted over many weeks, months or years, it’s not difficult to see how this can lead to decreased speeds. Defragmentation rearranges files so they are stored on sequential sectors of the disk, meaning the heads have less work to do to access the data, increasing read speeds. Over time, as existing files are deleted, fragmentation occurs, and new data is placed into the gaps left. When a file system is first initialised, it is essentially one contiguous block of empty space, and the file system can place newly-created files anywhere, in a near-optimal manner. If a file is fragmented across multiple sectors, it will take longer for the drive to read it.įragmentation occurs when a single file has been broken into multiple pieces. In order to read a file, your hard drive’s read/write heads have to move across the platters to access the data. Wait till Windows checks the defragmentation on the drive, and lists. Under Defragmentation, click on Defragment Now button. In the Properties dialog box that opens up, click Tools tab. Go to My Computer, right click on C drive and click Properties. Electromagnetic HDDs store data in chunks, known as sectors, and a single file could be broken up across multiple sectors. To defrag C drive on Windows 7, follow these steps. If your computer or laptop stores data on a hard disk drive (HDD), then defragmentation can be advantageous, and will improve its speeds. Defragmentation refers to the process of reorganising separate fragments of related data on a computer disk into the smallest number of contiguous regions, or fragments.
