Defragmenting a normal spinning hard drive is always recommended but should you defrag a hard drive that has no physical moving parts?
Solid State Hard Drives (SSD) are non-volatile memory chips instead of heads and platters like traditional magnetic hard drives.
Defragging a hard drive is usually performed so the files can be arranged on the drive to enable quicker access and read it in one section of the drive instead of having to find the fragmented data needed. It works a treat and defragging would always speed up your computer performance, but not so with Solid State Drives.
SSD’s and Defragging – Yes or No?
1. Data is not being read sequentially on a SSD so it doesn’t matter how the files are stored, the performance stays the same.
2. These drives have a limited amount of read / writes before they are useless. We have no idea when the limit is reached. This means that Defragging files on a SSD will therefore reduce the life of your drive and who wants to help degrade your hardware?
Defragging a hard drive that has spinning parts improves performance but defragging a SSD obviously is not a good idea. This is why you need to use the TRIM command to optimize a SSD.
Accidentally Defragging a SSD
If you accidentally defrag your solid state hard drive do not panic. You will not ruin your drive but imagine if you had the computer scheduled to defrag once a day? This would not be good for your SSD at all as defragging creates small write accesses which eventually degrade the drive.
