read the link I gave you. look at newegg, ssd transfers are all below 50MB/s, even cheap PATA can get 133MB/s. Just because you arnt smart doesnt mean you can assume.
I haven't read a whole lot about skull trail, but it is has an Intel chipset on the Motherboard, it would LIKELY support Crossfire.... only NVidia chipsets support SLI, no?
