I've just downloaded and installed Oracle Database XE 18c onto my Windows 10 PC. I choose to install it on a traditional magnetic hard disk drive just because I know that my system SSD has limited writes to begin with and has a much smaller capacity. I'm guessing, but I would say the installation took approximately 30 minutes having looked at the creation time of the related folders. Is this normal for given my choice of installation location (on a spinning platter) and all other factors I have already mentioned?
I wonder if Oracle is working on improvements and optimizations for the installation process. Although, it's probably not the highest priority since installations are kind of a one-off it would have been nice if it had installed a bit quicker.
