yasamoka wroteAvo I'll try to get you a USB3.0 card with my relatives but as Shant said your best bet is to buy a new board with integrated USB3.0...now the thing is of course you will never be saturated with a conventional hard drive for now since hard drives can never reach the theoretical limits of USB3.0, not even half of them, if half theoretical = real world (assuming USB3.0 is like USB2.0 in such a scenario)
i just found out that i don't have any open PCI-E slots , since my graphics card is so "small" and my motherboards design is VERY VERY "good"
the card has also blocked my 2 SATA ports
now i have connected my DVDRW s through eSATA
anyway thanks for the trouble, i guess i have no choice to get a new motherboard :/
