Editors' reviewTalk is cheap but bytes are cheaper: speed is the need with multiterabyte hard disks. It's too easy to leave high-capacity disks badly fragmented, robbing your system of critical performance advantages. There's one type of storage that delivers on speed, but at a high cost (as in money): SSDs (solid-state drives) don't use disks and should never be defragmented. But SSDs can be optimized, with care. PerfectDisk Free Defrag is a powerful disk defragmentation utility that can tell SSDs from HDDs. Its unique SSD Optimize feature consolidates the free space on SSDs with minimal impact, extending their useful life in your system.
PerfectDisk's Office-style ribbon has all the controls you need for scanning disks and running or scheduling defragmentation jobs. The program's upper half displayed all our drives by name, letter, type, and other headings, correctly identifying our "C" drive as an SSD. But we started with the basics by analyzing and defragmenting our "D" drive, a hard-disk drive (HDD) that is typical of the majority of installed drives. PerfectDisk reported a lot of information about our disk, data, and files, and recommended defragmenting the drive. Slow defragging is a major cause of disk neglect, but PerfectDisk has one of the fastest defragmentation engines we've tried. Of course, it also has a defrag map. Next we read up on PerfectDisk's SSD Optimize feature. Mollified, we ran the scan. But our SSD already ran at peak performance, and PerfectDisk recommended taking no action. We were relieved, since we weren't crazy about "optimizing" any SSD (as opposed to tweaking Windows for SSDs). But PerfectDisk's SSD Optimize feature may be just the thing for getting the most out of older, smaller-capacity SSDs that have been heavily used but still have life in them, especially if they cost way too much when new to retire while they can still serve.
The HTML-based Help manual reflects this program's enterprise-level origins, though some advanced features aren't included (or needed) in this fully functional freeware, such as remote control and Group Policy Support. PerfectDisk Free Defrag puts a fast defragmentation engine and cutting-edge features in the home user's hands.
