I received this unit and installed two 480gb SSD at 6gbs drives as my D (Data) drive.  I then added a 256 SSD at 6gbs for my C drive.  I set the two 480 drives to stripe raid with built in Raid controller on motherboard.  For some reason its not as fast as I thought it would be..  I ran Crystal Disk Mark and attached the pics below.  I use the PC to Convert Large Doc files to PDF.  I have all the docs and PDF files on the D drive. Any idea why this is not as fast as it should be?
