Same goes for the overall experience - way snappier. Lat but not least - the built-in defrag that comes with Windows - proved to be mediocre - compared to 3rd patty options (the improvement was visible after 1 defrag - especially since some of the top solutions - come with an optimizer which moves frequent apps to the beginning of the disk, thus - their loading time is incomparably faster (up to 5 max 10 seconds vs 30+ before.). That's even recommended by O&O Defrag (among the top solutions for optimizing HDDs), which is something i can attest from person experience (having auto-defrag On - i get random stuttering while gaming, an issue that was solved by disabling auto-defrag and superfetch). disabling the built-in defragmentation and doing that manually 'when the system is not in use' - it's still optimal solution. Tho, if there's still some people with HDDs - like an older laptop where an SSD upgrade is not an option - and still use that right for gaming, then. For most people - especially those who bought a system with SSD (or install main programs on it and use the HDD only for storing media content), that sounds about right.
