> grindingly slow process which tied up your computer too long and
> played Russian roulette with your spinning hard drive. Not anymore.
> Now, ALSoft's new, improved DiskExpress II Release 2.0.4 is the very
> fastest and safest disk optimisation software ever developed for the
> Mac. Using revolutionary Disk Optimatic? technology, only
> DiskExpress II has the intelligence to work intuitively and
> automatically to keep your drive optimized forever. DiskExpress II
> also has built-in extra sensitivity to any kind of user, serial or
> file activity, making it totally transparent in a work situation.
> So, you'll not only notice much faster disk performance than ever
> before, you'll see a dramatic improvement in file access times and
> in your productivity, right from the very first time you optimize.
> After all, when it comes to speed and your hard drive there's always
> a little varoom for improvement.

> The best hard-disk optimizer recently got better. DiskExpress II is

> DiskExpress II is controlled by a well-designed cdev and can be set

> regular preset time), or manually. Since I don't trust any program
> that's running automatically in the background, I rarely use the

> ### How Fragmentation Affects You And Your Macintosh
>
> Each time you copy or save a file to your hard disk, the potential
> exists for the file to be broken into two or more fragments. A file
> is said to be fragmented when it is stored in noncontiguous blocks
> (blocks not located next to each other ? [?]). Large amounts of
> contiguous free space cannot prevent file fragmentation. Adding,
> deleting, copying, duplicating, and modifying files are common tasks
> that will increase fragmentation and decrease the efficiency of your
> hard disk. To read an entire fragmented file, your hard drive must
> move its head from one part of a volume to another. The more
> fragmented a file becomes, the longer it takes to retrieve its
> information.
>
> ### How File Location Affects You And Your Macintosh
>
> [?] Under normal operation, seldom-used files (most of any user's
> files), free space and frequently used files are stored randomly
> throughout the disk. This places progressively higher demands on the
> disk heads as it accesses your frequently used files, resulting in
> longer file access times and decreasing individual productivity. |
>
> ### Why Simple Defragmentation Isn't The Answer
>
> Other defragmentation programs move pieces of individual files to
> adjacent locations on the disk. They make no provision for a file's
> frequency of use and how its location will effect the performance of
> your hard disk.
>
> ### Why ALSoft DiskExpress II Is The Only Answer
>
> DiskExpress II adapts to the way you work on your Macintosh in your
> particular environment. DiskExpress II monitors your daily file
> usage to determine the absolute optimum file placement on your hard
> disk. DiskExpress II intelligently groups your files [?] ?
> frequently used files are placed at the front of the hard disk, next
> to the directory, for optimum access. Free space is positioned next
> to the frequently used files to minimize the effects of any
> fragmentation that may occur between optimizations. Finally, seldom-
> used files and dormant files are placed out-of-the-way at the back
> of the disk.
