Why is it bad to defragment an SSD?
In: Technology
solid state drives don’t suffer a large performance penalty when a large set of data is stored in various physical locations of the medium: just about any cell required the same amount of time to read.
running a traditional defragmentation cycle writes a lot of data to the drive. this is further compounded by the issue that the “erase” operation is far less granular than the write operation (to change a small amount of data, a larger amount first must be erased). this puts a lot of wear on the media for no benefit. [the Wikipedia article on write application goes into a lot of detail about why this is problematic](https://en.m.wikipedia.org/wiki/Write_amplification)
