When using the 18.xx version drivers it seemed that disk access was very slow too. I'm using a 128gb SSD with 1Tb drive for data. All programs are installed on the SSD and that's where Corel does it Autobackup. The drive access is very noticeable in other programs too. I was happy with the final state they left me in, but Corel support did point me toward the older drivers to install.
