Note: This feature is only available with Diskeeper Server, and Diskeeper Professional.

Also Note: This feature is only available for NTFS volumes. FAT volumes are not supported. I-FAAST®, Intelligent File Access Acceleration Sequencing Technology improves file access and creation on NTFS volumes by up to 80% (average 10%-20%) above and beyond the improvement provided by defragmentation alone. This is the first industry implementation of “Disk Performance Calibration”, the modern evolution of the outdated and inconclusive disk optimization strategies of the past. Automatic Defragmentation keeps your volumes running as if they were new. I-FAAST Defragmentation works alongside Automatic Defragmentation to improve performance of your volumes to better than new.

When I-FAAST technology is enabled on a volume, Diskeeper runs specially-engineered benchmarks on the selected NTFS volumes to learn their individual performance characteristics. (Not all disks have the same characteristics.) Diskeeper then transparently monitors these volumes for file access frequency on an ongoing basis to determine which files are requested most often. Special analysis techniques prevent Diskeeper from being "fooled" by files that have been recently accessed.

Diskeeper sequences the files to take best advantage of both the logical characteristics and physical characteristics of the volume. The sequencing process is integrated with Automatic Defragmentation, so it’s virtually transparent to you.

Note that I-FAAST technology is only available when Automatic Defragmentation is enabled on a volume. The Automatic Defragmentation follows rules established by the I-FAAST engine based on the I-FAAST evaluation of the volume.

Also note that since I-FAAST defragmentation is an ongoing process based on conditions and activity patterns detected on your specific volumes, it can take up to a week or more for the full benefits of I-FAAST to become apparent.

It should be noted that the I-FAAST evaluation creates a hidden \Diskeeper folder at the root level of each volume on which it is run. This folder contains data files used by I-FAAST and should not be deleted when I-FAAST is enabled.

Also note that in the course of processing the files on the volume for best performance, I-FAAST will at times temporarily fragment one or more files. The fragmented state is only temporary and is only done in cases where it will be beneficial to the performance of the files on the volume.

I-FAAST intelligence allows Diskeeper to adapt to changing situations—so if the demands on a given system change, Diskeeper automatically adjusts its behavior accordingly.
