Tableau have released their Tableau high performance software imaging product today.
To install it you first must have installed the latest Tableau firmware updater. Once installed the interface is fairly simple to use. I found some of the terminology in the GUI a bit odd. For example the types of compression selectable for Encase e.01 files are No Compression, Fast Compression or Good Compression whilst Encase provides the options none, good or best. It seems that fast maps to good and good maps to best. There also does not seem to be the ability to actually name the created e.01 files- just their containing folders, again a little strange.
Now as far as performance is concerned in our environment it is slightly faster. We image to a mapped network drive on a san across a gigabit ethernet network. I imaged a Hitachi 80GB sata laptop hard disk via a Tableau T35i write blocker using FTK Imager 2.5.5 using the Encase e.01 format - imaging completed in 51 minutes. Using TIM to image the same drive took 44 minutes. In both cases maximum compression was selected. Obviously at this stage this testing is far from scientific but TIM seems to be between 10 to 15% faster. I will report how it goes on with larger 3.5 inch sata hard drives later.
