The only things that Apple and MS have in common:
-System architecture: AMD64
-Magnetic storage as default secondary storage
For the second one, of course, defragmentation is always a recommended maintenance task.
For magnetic (rotating HD) storage, YES on Windows; not really necessary on Mac, as the Mac filesystem doesn't degrade nearly so quickly nor are the effects as performance-stealing as with NTFS.
But for SSD (solid-state drive) storage, NO, NO, NO. All that defragging an SSD does is use up valuable write lifetime. There is no performance penalty from fragmentation on an SSD, because there is no head/arm motion. No moving parts.
Defrag is an obsolete procedure especially with the huge drives in use today.
I apologize for asking a question that has nothing to do with this thread. Asking here because I figure you have the tech knowledge to answere.
Most of the time, here on FR, I read only the excerpt, but, sometimes, I like to go to the source piece. Whenever I click on a “Breitbart” link, when I arrow back to FR, there is script missing on the page, such as screen names, as well as the choices under a post that start with “Reply”. The vertical lines are there, but the words are not.
I need to close the page down and start again to get the missing text back. Why does this happen?
