Some “opinions” out there state that the latest computers are not influenced by data fragmentation anymore due to the newest 7200 RPM drives and SATA interface, faster CPU’s, motherboards, whole gigs of RAM and what not. Windows Vista and Seven even have the built-in Windows defrag scheduled to run at idle time.
But the truth still is, if you want to get the best out of your machine, you have to do it for yourself. And if performance isn’t one of your worries, prolonging the life of your data and the life of your physical components should be.
the best choice simply depends on how the software fits the user’s needs and preferences.
