The cause of this slow-down is fragmentation, and when it happens, you need this app. It can be made better or worse by the design of the filesystem (and, actually, in this respect your Mac’s filesystem, HFS+, is one of the best), but in the long run there’s really no way to avoid this effect. This is an unavoidable consequence of the way hard disks work. If you use spinning disks, you’ll have noticed that over time it takes longer and longer to access your files, to start your applications and even to start your machine.
