What is DiskExpress Pro 3.0?

DiskExpress Pro is a disk defragmenter for classic Mac OS.

---

Files on a hard drive tend to fragment over time. As files grow, get modified, and are resaved, they end up scattered in pieces around the drive. In extreme cases, fragmentation can slow down disk access, as the disk’s heads search far and wide to read a file. Playback of huge files, such as QuickTime and sound files, begins to suffer.

Alsoft’s DiskExpress Pro cures file fragmentation by rewriting all the files into contiguous space on the drive. For safety, the application first checks blocks and directories for damage and corruption, and it never erases a file until it has moved the copy first.

It offers five alternatives for optimizing file placement, including options for maximum free space, quick access to most-used files, and faster optimization. This latest version of DiskExpress sports a neater and easier-to-use interface and adds more flexible scheduling.

It took DiskExpress about 1 1/4 hours to examine and optimize our moderately fragmented 1GB disk. By skipping disk diagnosis, however, another hard drive took about half that time. We tested our drives before and after optimization and found a humble speed increase of about 2.5 percent on the optimized drive. The results would probably be more dramatic on a badly fragmented disk.

Is disk optimization absolutely necessary? For the average user, perhaps not, but then neither is cleaning out the basement. DiskExpress Pro is smooth and easy to use, and it made us feel good about our hard drives again.
