A cheap alternative would be the ASUS U3S6 controller, the USB 3.0 and SATA 6Gb combines in one, so you could equip his "old" board with the new standard, if you consider that this controller only then this would be a cheap upgrade and you would save yourself an expensive motherboard purchase. The current forms Sata 2 and USB 2 one is somehow already reached its limits, when you can help out with SATA SSD faster hard drives, but USB does not match previously offered quick fix, even if the new drives and memory can still coming, the demand for memory and USB 3.0 Sata 3 boards enormous, the first tests have shown that the transition would be worthwhile.
Of course, the matter also has a catch, this controller will only fit on certain Asus boards, it says at least the manufacturer, on her site you can find a list of certain boards, but it has not lasted long, there are also other
manufacturers boards surfaced on the net that work with this controller. We have tested this and tried this little upgrade on two boards, one of them was the Maximus II Formula made by Asus and the second board was a EVGA P55 FTW, both boards have no USB 3.0 and SATA and a successful application would significantly upgraded.
Visually, the packaging looks very bright and somehow just Chinese, very colorful and not more attractive, that we will not hassle you as long as the content of the job, as a supplement, there is a manual, a driver CD and two Sata 3 cable, which you must use.
Structurally, everything is very logical, the internal SATA ports are the 3 that you need even when the hard drives, the external ports are USB 3.0, which is needed for external hard drives or memory sticks, these can be found on the back.
Here we can see the structure of the board, the USB 3.0 is powered by the NEC processor, the SATA controller is a Marvel, which can also be operated in AHCI mode and RAID support, of course this is also Sata II compatible, the whole thing is controlled by a high-BA50BC PEX8613 PCIe switch.
