SSD's do not have heads that need to be moved, nor do they have spinning latency. The whole purpose of defragmentation is to arrange the files in such a way as to make them more or less sequential, so that the heads do not have to be repositioned as much in order to read a file. It should be noted that this latency is measured in milliseconds (thousandth of a second) and is incurred every single time the heads have to be repositioned. Traditional spinning hard drives have a metric known as Access Time (or Seek Time, which is a slightly different measurement) that refers to the average amount of time it takes for the drive armature to physically reposition the heads so that they can begin reading data from a given sector of the disk (it may be more or less depending on how far the heads have to travel). Nowadays, more and more computers are using SSD, some computer users upgrade their HDD to SSD, which brings the question: How do we optimize an SSD, should we defrag an SSD?
