Good point about enabling Trim on SSD’s.
It’s interesting that there has been no mention of NOT defragmenting SSD’s - they just don’t like it.
Ausilogics has a defragmenter that has an SSD option, I use it to analyze my SSD and find that it’s never over 1% fragmented.
Lol.. defraging SSD is losing SSD life :p
Anyone that is semi-tech-savy should know NOT to defrag an SSD
btw, what ever happened to the squared crystal that could hold petabytes (from an article from about a decade ago)..
Defragging a spinning hard drive makes sense as the drive head can read the data in a single pass instead of having to reposition the head to different tracks on the drive. Physical motion of the drive head is glacially slow compared to light-speed.
On an SSD, there are no physical moving parts, so if a file is fragmented in several address spaces, a few extra light-speed lookups to assemble the file is not noticeable.
You're right about SSD's not liking rewrites to push data around. SSDs have a finite number of times a storage cell can be modified thru re-write, after which the SSD has to mark off that section of memory as dead. So it's better not to attempt to defrag an SSD and in fact it is beneficial to not do extra writes.
