Defragmenting
                      your hard disk is a procedure which unites all the disparate
                      file fragments into proper contiguous files. The end result
                      ideally is shorter file save times and shorter file loading
                      times. The corollary to the end result is that your hard
                      disk doesn't have to work as hard to store or load files—the
                      smaller the number of file pieces, the less time the hard
                      disk has to spend searching for and storing or assembling
                      everything. The effort put in by the operating system is
                      correspondingly reduced as well—not as much work
                      to do sorting out so many file pieces. Of course the chances
                      of the operating system making a mistake on any of those
                      individual file pieces is also correspondingly reduced.
                    
                    So
                        what's the down side? Nothing at all really, unless the
                        defragmentation software maker has done some sloppy programming
                        and left the software in such a state that it takes forever
                        to get the job done. But a well designed drive or file
                        defragmentation utility generally keeps the home fires
                        burning bright.
                    And
                        how does Diskeeper 10 Professional Premier stack up against
                        these requirements? In a word, perfectly. The Premier
                        version has three main benefits which distinguish it
                        from other Diskeeper versions: a) I-FAAST, b) expanded
                        support for large drive volumes up to 2 Terabytes (TB),
                        and c) native support for 64-bit operating systems (mainly,
                        Windows XP 64-Bit).
                    I think
                        the most important improvement is I-FAAST, Diskeeper's
                        acronym for Intelligent File Access Acceleration Sequencing
                        Technology. It's an adaptive file sequencing technology.
                        After the I-FAAST sub-utility built into Diskeeper spends
                        two or three minutes benchmarking your drives (IDE, SATA,
                        SCSI, RAID, etc.) to figure out their individual performance
                        characteristics, it continues to monitor your file access
                        patterns to determine which files are used most frequently.
                        During an actual I-FAAST defrag job, it sequences the
                        files it has noted in order to give you some additional
                        speed whenever you access those frequently used files.
                        Projects, media files and games load faster. The improvement
                        is measurable, and more important, noticeable. I-FAAST
                        defrag jobs are set up in addition to regular defrag
                        jobs. The process is simple using Diskeeper's built-in
                        wizards.
                    Before
                        upgrading half a dozen Windows XP and Windows 2000 computers
                        to Diskeeper 10 Professional Premier, and installing
                        version 10 on another half dozen machines with no defragmentation
                        software of any kind, I spent a couple of hours benchmarking
                        each machine. That is, I did some file loading tests
                        using a stopwatch. What I found on the upgraded machines
                        after retiming the same file loads was a 5% average improvement
                        after running consecutive defragmentation and I-FAAST
                        jobs. On the previously unmaintained machines (which
                        Diskeeper 10 flagged as being extremely fragmented),
                        I measured an average improvement of 35% after running
                        consecutive defragmentation and I-FAAST jobs. I was impressed
                        enough to purchase additional version 10 licenses for
                        the rest of our network.
                  
                  Here's
                      an interesting Diskeeper-related statistic that I recently
                      calculated. If my staff of research and development specialists
                      continue to regularly work on project files as a matter
                      of course (they will), file fragmentation can add as much
                      as 10 seconds of file loading time to each and every task.
                      On average, my researchers and developers work on approximately
                      10 different large files every day, loading each file as
                      many as 5 times per day. There are 15 researchers and developers,
                      on average, in the office every day. An additional 10 seconds
                      of loading time amounts to 750 seconds of wasted time each
                      day. Multiply that by 5.5 days per week and 45 weeks per
                      year and you get 185,625 seconds. That's actually 51.5
                      hours of wasted time. Even if I err on the side of caution
                      in my calculations and chop the whole thing in half, I
                      still get approximately 25 hours each year of time spent
                      doing nothing but waiting for large files to load. That
                      25 hours costs my and my company approximately $2,500.
                      But fifteen Diskeeper licenses will only cost me $1,185,
                      not too mention the revenue I can generate during those
                      25 otherwise lost hours. I do some funny calculations sometimes
                      because I spend a lot time immersed in research and data
                      and numbers. The bottom line for my business is that every
                      bit of time I save is money in the bank. The other bottom
                      line is that as long as I install and schedule the use
                      of effective maintenance tools, I don't have to think about
                      this stuff in the first place.
 
                  Cons: I'd
                      like to see the defragmentation process priority selection
                      sub-dialog available globally. Right now it's accessible
                      only from the Job Properties dialog when doing a manual
                      defrag or creating a Set It & Forget It schedule.
                  Pros: The
                      effects of file fragmentation are widespread. Slow performance,
                      long boot-times, random crashes and freeze-ups, and sometimes
                      a complete inability to boot up are problems often blamed
                      on operating systems when disk fragmentation is frequently
                      the real culprit. You need to use something and Diskeeper
                      is a great choice. The user interface tweaks, particularly
                      the revised and helpful text in the guide pane of the main
                      program window, are great improvements. I-FAAST really
                      works and the additional cost to get it in Professional
                      Premier is well worth it. Overall, regular file defragmentation
                      jobs are faster than ever. You can now run primary, secondary
                      and I-FAAST defrag jobs, all based on different criteria.
                      Boot-time defragmentation jobs are easy to set up with
                      a single click from the separate boot-time defrag job dialog.
                      Diskeeper 10 Professional Premier is a great maintenance
                      tool for any and all home-office and small business Windows
                      computers. I measured specific performance improvements
                      on most of the computers on my network after upgrading
                      from Diskeeper 9 to version 10. On several machines that
                      were running without any file defragmentation software
                      of any kind, the improvements eked out by version 10 were
                      terrific. In one case—a general purpose Windows XP
                      Professional machine used by half a dozen different people
                      each and every week—Diskeeper actually saved the
                      machine from retirement. I was going to replace it, but
                      the Diskeeper maintenance (and a subsequent once-over with
                      SpinRite 6) has given the machine a new lease on life.
                      Highly recommended.
