Ralf is right about no harm to SSDs.

My guess is that a hybrid suspend has somehow been enabled on your system.

I'm having power management issues myself. And, one of the problems is
figuring out what software is doing exactly what. On xubuntu, there are
several specific power management apps that could be controlling the
suspend process. In addition, your init system has a role as well.

If you're running 16.04 or later, systemd is your init (believed systemd
took over with 15.04, but not sure). You can check the log files with
journalctl. Type h once started to see all the options for navigating
the log files.

Here are the notes about systemd from the ubuntu 15.04 release notes:

Also, check out /var/log to see if the suspend.log file has any info.

For future reference, and especially with possible hardware-related
issues, include not only the OS but also relevant hardware details.

inxi -S 	* gives you the current kernel et al.

inxi 		* provides basic info

inxi -h 	* provides all the options available in inxi
