Since my OS and applications are loaded into memory upon boot, isn't there no advantage from having my OS on an SSD boot drive for a server that is kept up 24/7? I know there are several assumptions that depend on how I use that server, so for the purpose of this question, let's assume:
- No I/O tasks on my applications.
- No applications on disk that need to be loaded after boot.
- No need for fast reboot after a crash.
Basically, I want to know if there is some random I/O carried out by kernel processes that I'm unaware of?
