First, there is a lot of similar question everywhere, even here on AskUbuntu. I have bought Samsung 850 Evo Basic, 120 GB model. I have existent system installed on classic 500GB HDD. Question is, how to migrate existent Ubuntu installation from HDD to SSD, and tweak SSD for optimal performance using Ubuntu 14.04. I have 8GB of RAM, should I disable swap and how frequently should I run trim? Setting cron job seem like good idea.
Disk usage is as follows:
Filesystem Size Used Avail Use% Mounted on /dev/sda7 131G 32G 92G 26% / none 4,0K 0 4,0K 0% /sys/fs/cgroup udev 3,9G 4,0K 3,9G 1% /dev tmpfs 797M 1,4M 796M 1% /run none 5,0M 0 5,0M 0% /run/lock none 3,9G 84K 3,9G 1% /run/shm
none 100M 28K 100M 1% /run/user
Can I just cp all from / and then update GRUB?
