Should I get HDD (SAS) or SSD for site, forums and possibly gaming servers?

  • I currently have a RS 4000 G8SE with 140GB SSD.

    My question if I should switch from SSD to SAS and I'd like to know some people who have experience in this department.

    I currently use the server for multiple forums and websites, IRC bouncer, Discord bots. What do you guys use from SSD and for SAS? And why? Should I switch to SAS instead?

    Only reason why I'm considering it because with SAS I'd be almost getting 1TB, rather than 140GB SSD.
