I'm about to buy the x51 extreme I think! For the hard drive it says (256GB SSD SATA 6Gb/s + 1TB SATA 3Gb/s (5,400RPM) 16MB Cache). Does this mean that I get 256GB of flash storage and 1TB of HDD???? If this is true, then do I get the option of where I get to save things ( flash or hdd)? Please help thanks.
