Will a disk defragmentation benefit my SSD?

There is no benefit from defragmenting your SSD. Traditional hard disks fragment data, which reduces storage capacity and in most cases, performance. Fragmentation occurs when allocated space is either insufficient to fill or over allocated and goes to waste. Accessing 64KB of data is quicker than accessing eight 8KB of data on a hard disk, but this is not the case with SSDs; due to their near zero seek times. Fragmented SSD drives do not see a drop in performance. In fact fragmenting SSDs causes unnecessary wear to the device.
