PerfectDisk Professional 12.5 309 released Nov 29, 2011 (New Release)

Fragmentation Prevention with OptiWrite:
· PerfectDisk's new OptiWrite technology prevents most fragmentation in your drive before it occurs, which prevents your system from slowing down. OptiWrite detects when Windows is going to fragment files and intelligently redirects I/O to stop the fragmentation from occuring. System performance is maintained and the need to utilize CPU and Disk I/O resources to defragment files is greatly reduced. Because less defragmentation is needed, there is a direct benefit in the form of energy saved in both CPU usage and in the reading and writing to a disk. It saves users both in energy costs and in the time required to defragment a file system.

Intelligent SSD Optimization:
· SSD Optimize is an optimization method for SSDs that focuses on free space consolidation without defragmentation of files. Solid State Drives are not affected by file fragmentation like traditional electromechanical disk drives.

PerfectDisk Professional 12.290 released Sep 9, 2011 (New Release)

There were several issues where the S.M.A.R.T. tab indicated outrageously high temperatures. This was due to PerfectDisk not recognizing the drive model and trying to apply an incorrect set of rules to interpret the S.M.A.R.T. data. In this build PerfectDisk will only provide S.M.A.R.T. data for drives in recognizes. More drives will be added in later service packs.
· Real time defragmentation aggressively allocated space to prevent additional fragmentation. This resulted in consuming large amounts of space unnecessarily. The main symptom was rapidly growing log files. This has been corrected.
· On some Windows XP systems the drives were grayed out annd PerfectDisk could not be used. This was due an issue with WMI which has been corrected.
· On Windows 7, the hidden 100mb partition created to support bitlocker has been added to the excluded drives list automatically. There is no benefit in defragmenting this partition.

PerfectDisk Professional 12.267 released Jun 9, 2011 (New Release)

OptiWrite to Prevent Fragmentation:
· PerfectDisk's new OptiWrite technology prevents most fragmentation on your drive before it occurs, which prevents degradation of your system’s performance. OptiWrite detects when Windows is going to fragment files and intelligently redirects I/O so that most fragmentation does not occur. As a result, the need to utilize CPU and Disk I/O resources to defragment files is greatly reduced. Because less work is needed to optimize the drive, there is a direct benefit in the form of energy saved in both CPU usage and in the reading and writing to a disk. It saves users both in energy costs and in the time required to optimize the drive.

Flexibility with Multiple Optimization Options:
· Each drive and each user is unique, therefore PerfectDisk has different optimization algorithms that can be set on a per drive basis depending on the type and needs of that drive.
