"Keeps getting better and better!"
operates silently in the background; runs only when CPU is idle; puts directories, folders at the front of the hard drive for quick access. Also puts more frequently accessed files near the front of the drive, for same reason.
none that I can think of
This nice defrag utility utilizes system resources so as to be barely noticed. Optimizes your hard drive in the background. And uses up very little RAM and CPU time. Highly recommend. I like PerfectDisk, a paid product; but Smart Defrag gives PerfectDisk a run for its money; and, I think, uses up fewer RAM and CPU cycles. Highly recommend this free product!
