When I was using a mechanical hard drive, I didn't need worry about having to manually defragment my hard drive and simply let Windows Vista / Windows 7 defragment my disk on the predefined schedule and the system was running absolutely fine. The amount of maintenance you need to perform on a Windows Vista or a Windows 7 based system can be kept to a minimal if you practice smart usage habits from the very beginning. You don't need any of these third-party applications that you can get a hold off left, right and center these days to keep your system running in an optimal way.
