[QUOTE="MacInWin, post: 1810031, member: 396914"] And for anyone reading this and not going to Randy's site to read the article, there is a clear warning there: The most common reason for not defragging an SSD is that it generates a lot of read/write actions to the SSD, and the life of SSDs is measured in the number of read/writes. So defragging will shorten the life of the SSD. Also, defragging an SSD will not result in major improvement in speed because defragging is a way to lessen the latency delay on a spinning drive while the heads move and then wait for the proper sector to come under the head to be read/written to. In an SSD, the latency is exactly the same on every block and since nothing is moving, the latency is very, vary small in any event. So, don't defrag an SSD, ever. [/QUOTE]
