The 2 T regular drive in it makes it slower than smoke off poo---  but I"m replacing that with a 2T ssd, and adding a 500 gig for operating system, and use the 2T for SEPARATE storage.. that way I never lose anything no matter what goes down.... Iv'e tested it with one I had here already and it is VERY FAST with those... but I need it in my previous system-- have new ones coming.  It cost a bit more but VERY worth it-- this will make a GREAT- fast, small form factor (room saver) and VERY good system... I LOVE IT-- great choice.
