I have a Samsung Gaming Series Laptop that is about 3 years old running 16.04 that I tried to upgrade from 2 750GB HDDs to a 1.5 TB 5400 RPM HDD for Storage and a 500GB Samsung Evo 850. I hit a brick wall here, and most of the info concerning SSDs is more than two years old.
Right now I have a running Ubuntu with partitions all over the place, each with their own mount point.
/tmp are on HDD, root and
/usr are on SSD. Windows is intalled fully on SSD, because I use it only for gaming (shame on me, but GTAV and Skyrim on Wine would be a pain).
While Windows boots in about 5 seconds, Ubuntu needs up to two minutes, which is not what I got a SSD for.
So which directories are save to put on the SSD? Some say I should limit writes as much as I can, some say modern SSDs are fine with loads of writes. Now where should I put which partitions? Can I move /home to SSD? Maybe with links to a bigger HDD Folder for files that don't need to be on the SSD? Which steps should I take to optimize for performance and longevity? And are there any things I should be super cautious about?
