I am planning on buying the Asus U3S6, because I want an SSD (OCZ vertex 3) and want to get the most out of it as I do not own a SATA 6 mobo! I was wondering, because the card requires a PCI-E 2.0 (x4) , I only have a x16 free on my mobo, and it is only Gen 1=(PCI-E 1.0) I know that plugging a x4 pci express card would work if I plugged it into my spare x16 slot, but because the x16 is only PCI-E 1.0, and the Asus card requires a 2.0 slot, will I get the most performance out of the card? I have looked all over the internet, but can't find many answers? Because, if it won't give me a performance increase because it's gen 1 my slot, there's no point purchasing the card in the end!
 
If your second physical x16 slot is PCIE v1.x and only runs at x4 speed, then this is equivalent to 500MB/s per direction or a x2 speed PCIE v2.x slot. Therefore you would get pretty much all the performance possible out of a SSD like the Vertex 3.

The ASUS card is PCIE v2.x, but this standard is required to be backwards compatible with PCIE v1.x slots - it just means they will run with half the normal bandwidth, and as mentioned above this should be enough for the application you are using.
 
I have the asus card with my C300 and with atto I can easily get 370+mb/s read. So I think as long as you use a x16 slot like I am done then you should be ok with the 500mb/s read/write speeds.
 
No, you will not reach the full speed...

The Asus card uses a Marvell controller which the Vertex 3 does not like (because the controller is well... not as good as Intel controller).

So with this card and a Vertex 3, you will not have the full advertised speed... In fact writes will suffer quite a lot if I remember correctly from a post I saw somewhere in this forum.

the slot is a x16 gen 1 and the asus card requires a x4 gen 2 slot. My board clocks down to two pci-e x8 with a second card in my x16 slot
