GeneralTo defrag a SSD or not to defrag a SSD Pin

A couple of threads earlier I asked the question: Should one defrag a SSD or not. I got different answers so I tried an experiment:

I am very familiar with Macrium Reflect to create images of my C: drive, which is a NVMe M.2 SSD. Reflect works extremely fast and will create an image as fast as the C: can feed it data.

So I created a system image and noted the speed at which Reflect was writing it to the target. It reached a maximum speed of 6.7 GB/s. Then I ran "defrag C:" from a command prompt and got a report that the C: drive was 20% fragmented before it was successfully defragged.

Then I ran Reflect again and this time it reached a maximum speed of 7.8 GB/s!

It seems to me the speed at which SSD can read large volumes of data is affected by fragmentation.

Note: I ran the trim command on the same drive yesterday and it seems this did not remedy the fragmentation.

Thanks to all those who expressed an opinion on SSD fragmentation, but I will be running it from time to time. If that shortens the life of the SSD, well, they are cheap and easy to replace! Smile | :)

Note: Windows reported as follows after defragging the C: drive:

Pre-Optimization Report:

Volume Information:
Volume size = 930.65 GB
Free space = 868.64 GB
Total fragmented space = 20%
Largest free space size = 863.72 GB

Note: File fragments larger than 64MB are not included in the fragmentation statistics.

The operation completed successfully.

Post Defragmentation Report:

Volume Information:
Volume size = 930.65 GB
Free space = 868.64 GB
Total fragmented space = 0%
Largest free space size = 863.75 GB

Note: File fragments larger than 64MB are not included in the fragmentation statistics.
Ok, I have had my coffee, so you can all come out now!
