NOW there is something utilizing it.
New Sandforce series SSD’s deliver 550 Mbyte/s and bottleneck a SATA II easily.
Too bad this card is insanely picky about what mainboards it works on. Mine runns only in x1 mode so it’s a total write-off. Others have more luck and blast away at over 550 Mbyte/s. Sigh…

that’s no typo dude, SATA3 means SATA version 3 speed 6Gbps, SATA2 means SATA 3Gbps and so on..

Dear author: If you used 2 SATA 3 ports at the time, then how speed of this card?
PCIe x4 of this card plug in PCIe x4 2.0 slot running at 2.5GT/s or 5.0GT/s?
The motherboard using for this test is 7P755H LE, this mortherboard supports PCIe 2.0 x16 (2.5 GT/s) is equivalent with PCIe 1.0 –> do this card only need PCIe 1.0 slot?

This USB 3 SATA 6 PCIE x4 card has no separate power connector and I do not wish to burn up another mother board. Where is a PCIE x6 version w/ a power connector? Not made yet?, I’ll wait.

Chuc: What are you talking about? The review of the Seagate went up the same day as this review did…

Already more than one month and a half has passed since the review, and the next one with the seagate hdd didn’t show up like you wrote it would?

I have to agreed with comments about this test is really not valid comparison for this Asus U3S6 card. It is in a diffrent class compare to the USB 3.0 only adapter. If you only need USB 3.0 then it will not make any diffrent weather the card using a x4 or x1 PCIe. The NEC chipset used in all USB 3.0 adapter is only a x1 PCIe to 2 port USB 3.0.

PCI-e x1… PCI-e x4 is still a bottleneck on this card if you were to stress all the USB 3.0 and SATA III ports to maximum. With PCI-e x1, you’d only be able to use one port at a time, lol.. 16gbps > 5gbps

Well, as for ‘wasting’ an x16 slot, and that the author seems to feel this would have been better suited to being designed as a 1X card, I have to question if he understands anything about the bandwidth requirements of a USB 3/6Gb SATA *combo* card sitting in a PCIe slot. Put a couple of SSDs on those SATA ports, and then try to use a USB 3.0 port at the same time…

The author of this article is poorly educated on speed limitations. The only way you can see a difference between PCIE x1 and x4 is when you saturate the x1 speed cap. The article used nothing but slow drives which themselves are the limitations. It’s quite obvious there would be no visible difference in speed.

PCIE x1 slots run at 1.0 spec, meaning they hit their limits at 250 MB/s (many SSDs already surpass this rate at sequential reads). With Asus using a PCIE 2.0 x4 slot, this limitation is raised to 2 GB/s.

To the author: Try connecting a fast USB3.0 SSD to the Asus and Unitek cards, and I guarantee you will see a difference in speed.

There is a typo in your “PROS” list. You list the card as usb 3 and SATA THREE.

Good article, wish you ahd done more speed comparisons and tests the SATA6 aspect as well tho
