I have been using a basic 128 SSD partitioned with basically Win 8 installed on one partition of 60 gb. That worked ok, but I decided to upgrade to a larger faster model and just installed the image from the smaller one on to the new. I am not sure if that was the best way to do it as it does not perform any better and maybe a little slower. I received an attractive email from Perfect Disk and installed that but to no good effect. I have never found de-fraggers to be of any benefit so don't why I changed my mind over this. Any thoughts/advice would be welcome.
