E-tail availability in two weeks

ASUS started shipping the first motherboards with support for the USB 3.0 and 6Gbps SATA interfaces two months ago at the beginning of November. The first mobos were targeted at enthusiasts, but soon made their way into the mainstream. Gigabyte followed suit, and shipped seven new motherboards with support for the new interfaces as well.

At that time, ASUS told DailyTech that it was developing a PCIe adapter for all of its motherboard customers who wanted to upgrade to the new standards. The U3S6 card would plug into a PCIe x4 or x8 connector and add two USB 3.0 and two 6Gbps SATA ports to an ASUS system. 

The company has now informed us that development and testing on the new U3S6 card has finished, and mass production has started. It will begin shipping to the channel next week, with e-tail availability expected for two weeks from now. Best of all, the U3S6 card will go on sale with a retail price of only $30.

Although ASUS has only officially validated the add-in card on their motherboards, there should be no problems encountered by customers wishing to use the adapter card on motherboards made by other brands, since the U3S6 complies fully with the PCIe specifications.

There will be plenty of new devices available soon over the next few months, including Crucial's superfast C300 RealSSD and Super Talent's USB 3.0 flash drive. If you need more USB 3.0 ports, a new hub using VIA's Hub Controller may be an option.

nice card. but seriously, who's got a x4 slot? aint intel and motherboard manufacturers ruined it with x1 slot barrage?

well in theory you can use the 1x slots if you file away the rear of the slot (the card should auto sync to 1x speeds). I tried this with a graphics card but it didn't work because i damaged 2 of the pins. If someone tries to do it, start filing away from the OUTSIDE of the slot. you never know it might work.

if you have a more expensive mobo then you can use your spare 8x or 16x slots and get full speed but as was already mentioned here that might drop your 16x slot to 8x electrically

If it was only 1x, you could get a bottleneck with heavy traffic on both controllers. So it being a 4x board is a very good thing. Also for motherboards without PCIe2.0 use of this board on a 1x would be somewhat slow with heavy traffic.

Those who are buying this is early adaptors, with higher demands. Most of them will have a 4x-slot on the motherboard - this with using a 4x/8x/16x "inteded" for a second videoboard.

I have this running on MSI P45-board that has a PCEe16x@8x, populated with this 4x board...

Ah, here's a newbie question that I'll bet a lot of others might not know either - can an x4 card like this one be put into a PCI-E x16 sized slot on a motherboard?

Some PCI-E x16 slots only have x4 bandwidth anyway (I think my 790X chipset board is like this...) which would be a good match if it does work this way. Can anyone confirm?

Yep.

Even a 1x PCIe card can be put in a 16x and work just fine (though you'd have anchoring issues). PCIe is fully compatible scaling up, so this "4x" board would only not work right with a 1x slot :P.

I think that this card is designed with the Asus P7P55D motherboards in mind.
I don't remember well but the second 16x slot was not connected directly to the processor or something like that, and it could work as 4x without crippling the video card slot.

So it should be fine on asus motherboards. On other mobos you have to put it in a 16x slot and risk to get 8x/8x

Many boards do have x16 physical slots that are only x8 or x4 electrical. They use full x16 slots simply for physical connector compatibility concerns, as x16 slots allow for any sized card but allows it to drop down to lower x8 or x4 bandwidth. Cheaper versions do just cut out the back of the slot and only extend the plastic connector to match the actual electrical lanes.

Ideally, you wouldn't want to run this card in an x1 slot especially if you have individual drives that actually approach that 500MB/s provided by a single x1 PCIe link.
