For those that don't already know, do NOT defrag the SSD. I mention it only because the IT guy ran a defrag in the video.
This warning can now be downgraded from a "do not" to "there no need". It used to be that disk intensive activities such as defragging or using the SSD for swap were no-nos. But with wear-leveling any "sectors" which get a lot of use are migrated to different physical locations on the chips. So repeated writes end up wearing out all the empty space across the drive evenly. On top of that, the erase/write cycle count for any cell on SSD is now in the hundreds of thousands. The time of the old chips which died after simply hundreds of cycles is now over.
That said, because there's no physical head moving, while waiting for a particular point on the disk to come around again. There's no benefit of defragging SSD. Any sector which needs to be read can be directly addressed with only the smallest of penalty for non-sequential reads (which is almost always in effect because of the for-mentioned wear-leveling, what the OS thinks is a sequential read or write more than likely is not).
