Having lots of memory can serve as a poor-man's SSD. At least on a Linux system files are read from the disk and left in memory until that memory is needed for something else. This can increase responsiveness by reducing the need to go to disk for frequently used filesystem data.

The price of SSDs has come down sufficiently that you probably could say that having lots of memory is a stupid way to emulate having an SSD ;)
But the speed of RAM is still at least one order of magnitude faster than the SSD so there is still an advantage even with a faster fixed disk.
