You should not defrag an ssd. Maybe once a year! Although i did see that diskeeper have an ssd optimizer. does not defrag it but consolidates the free space. It has apparently been proven to speed up and maintain an ssd in the long run.

No. Never. Definitely not.

Negative.

SSD can optimize themselves better than some 3rd party tool which has no information about the SSD controller design.

This is not the case for SSDs as LBAs for flash pages change based on its wear levelling algorithm!

Even if a file is stored in sequential blocks according to its LBA address (ie. the file is not fragmented according to the OS/defrag program), it might be sprawed across several flash chips!

So what about this conundrum...

I have my steam games on my F3, I used steam mover to move Arma 2 onto my C300. When I defrag my F3 will it also defrag the Arma 2 files on the C300?

I wouldn't think it would defrag the SSD
And I do here what you're saying!
But I'm thinking the defrag is at more of a physical level!

But that's just a guess

No because SSD's are flash memory, and don't get fragmented, and access times are next to zero, making fragmenting irrelevant.
post #30 of 35
Haha someone voted "yes".

Sure, you can do it, but it won't improve performance. In fact, it will do the opposite. Flash cells have a limited number of write cycles, and defragmenting an SSD (moving around the files) will cause unnecessary wear on the flash cells.
