Ubuntu is faster than Windows but the big difference is speed and durability. SSD has a faster read-write speed no matter the OS. It has no moving parts either so it won’t have a head crash, etc. HDD is slower but it won’t burn out sections over time lime an SSD can (though they are getting better about that).
Can Linux run on SSD drives?
Install Linux completely on the SSD. You’ll get full advantage of SSD speed, but then you will have only a limited disk space. This could work if you have 180 GB or 200 GB or more on SSD but won’t work with 120 GB SSD. Install Linux completely on the HDD.
Is Ubuntu bad for SSD?
Ubuntu would most likely damage it less because the operating system itself uses less disk space. All modern SSD devices support a feature called wear leveling that occurs in the background.
