Would the use of several devices reduce disk io blocking?

I run a webserverweb server with a couple of webapplicationsweb applications in apache on the same device.

The other day I had to run a chown -Rchown -R and a chmod -Rchmod -R on a folder containing over 100 000 files. This took some time and I realized that the disk ioIO caused all applications to run extremlyextremely slow for a long time. The CPU usage was also high for minutes after the commands where done.

Would the use of several devices reduce disk IO blocking?

If iI have had each applications on different devices would the disk ioIO affect the overall performance of the server the same way?

Are the disk ioIO blocking divided per disk or on the system as a whole?
