X-bit Labs published the second part of their series on defragmentation. This time they take a look at PerfectDisk 8.0:
The PerfectDisk 8.0 program that we picked for our today’s tests following our readers’ recommendations can be considered one of the most advanced tools. Besides the above mentioned service files defragmentation, it also knows to defragment NTFS meta-data, combines all the free space on the hard disk drive into largest possible blocks of adjacent clusters, supports fully functional management from the command prompt, and requires only 5% of the hard disk drive free space to operate. The latter feature makes its positively different from the defragmentation tool built into the Windows XP, for instance, which requires at least 15% of the hard disk drive storage capacity to be free for proper operation. This feature will definitely be very important for those users who are forced to use up almost entire storage capacity of their hard disk drives.
