No, I don't experience any problems. I am just not sure, if it's fast as it should be or not. I'm running: GA-F2A55M-DS2.
I just realized on their website description, "8 USB 2.0 and 4 SATA2 ports with RAID 0,1,10 support". I think the problem might be because it's using SATA2, instead of SATA3, that's why it's not performing at full speed. What do you think?
