What is defragging?
In basic terms, defragmenting is exactly what it sounds like: it's a reversal of the fact that data gets fragmented across your hard drive. Over time as data is saved, resaved, or deleted on your drive, small packets of information end up deposited in random places all over the disk. This then takes longer to find as the read head has to move to multiple positions on the disk rather than being able to read the data in consecutive sectors.
Should I defrag?
If your PC has an SSD installed rather than a spinning hard drive then the answer is an unequivocal no. It won’t help in any way and may very well reduce the life of your drive. Later versions of Windows automatically run optimisation routines on SSDs anyway (as do the SSD controllers themselves), so you can just let that run its course and you’ll be fine.
