Disk fragmentation leads to system slowdowns, PC crashes, slow startup and shutdown and sometimes to system failures. Auslogics Disk Defrag is designed for fast optimization of todays modern hard disks. Get the maximum performance out of your expensive hardware investments, improve your computers performance and stability.Hard disks are by far the slowest component in your computer. CPU and memory work much faster than hard disks because they do not have moving parts. Therefore fragmented disks often become a bottleneck of the system performance. Besides causing slowdowns, fragmentation makes the hard drive disk heads move frequently when reading files which leads to freeze-ups and system crashes. It is important to keep your disks defragmented and optimized as much as possible.
