This is true but the overall effect of an ssd is that the system will be a little snappier since disk accesses are much faster. Accessing the disk is only a portion of overall system performance, as Tech points out, RAM, CPU, Bus and video operations will not be effected.
Regardless, all of my computers have an ssd as the boot drive.
