Does the card with the 20 pin USB 3.0 header maintain full USB 3.0 speeds or does this maintain full speed for each port?

I really don't have any way to measure these things, other than simple observation. My experience has been excellent. Compared to USB 2, this setup has definitely, at the VERY least, doubled the USB 2. When using multiple ports simultaneously, I did not detect any slow-down. Install was easy enough, and the company's support has been very responsive. I needed to contact them because Windows didn't recognize the hardware. Highpoint offered a "dummie" driver to prevent Windows Device Manager from constantly displaying a warning that there is something wrong with a device. The device works very well, and I have never experienced any problems with it. I hope this response helps you! I really don't have any way to measure these things, other than simple observation.

According the Highpoint RocketU 1142A specs as reprinted on the Amazon product page, the internal port is a 20-pin header with 10 Gbps throughput while the two external ports are each standard USB-Type A at 5 Gbps each. That is corroborated by the fact that USB TYPE-A connectors only have 10 connections (9 wires + common shell) whereas the internal 20-pin header can support two USB channels or, by bonding, provide a double wide bandwidth of 10 Gbps.

According to the product spec, it maintains full USB 3.0 speed for each of the four ports (2 external and 2 internal - via the 20-pin header). I haven't tested that, though.

Yes but throughput on USB 3.0 is still limited to about 40mbps due to the chipset used. I found the Transcend parts support bandwidth that matches the throughput of MSXD.

The card supports a 4-Bay e-Sata enclosure on my MacPro with no problems and 3X the performance of USB 2.0. From what I have read in the comments on Amazon, the card will only support one multiport device per card because the port multiplier only seems to apply to one port. I expect to connect another multi-bay enclosure in the future but it will be one with built-in RAID so that it only presents a one device appearance to the card.

I assume by "regular PCI-E", you mean PCI-E x1. This Highpoint card is PCI-E x4 and has two advantages over x1: 1. it has enough bandwidth to cover the full theoretical transfer speed limit of USB 3.0 and 2. it does not require additional power (in the form of a molex connector, for example).

Correct. As in the description...2 of the 4 USB ports on top are 3.0. Of course, your mainboard will need to have 3.0 headers to connect these to.

Yes, it is PCIe 3.0 compliant. Of course this is backwards compatible with 2.0, and your system will determine the actual data rate.

Your USB speeds will only be as fast as the slowest component you plug into it. If you plug a USB 2.0 external harddrive into a USB 3.0 you'll get 2.0 speeds. If you plug this hub into a USB 2.0 port, you'll get USB 2.0 speeds. Depending on the age of your PC you can probably get an add-on PCI card with USB 3.0 ports if you do not want to upgrade.

My Gigabyte card only has one USB header on the board. My only thought for why there might be a second USB header is that this board may have multiple models (perhaps one that comes with additional USB ports) and for cost-savings they re-use components. That's just a wild guess. Again, my card does not have a second USB header - just the one for enabling bluetooth connectivity.

Not 100% sure. But I do know the transfer speed is less than 20mb/s. Very disappointing for a 3.0 USB

This plugs directly into the PCIe bus, you don't need to connect to any USB pins on the mother board. For the internal USB Port for connecting a USB hub on the front of the PC for example, I believe it had a standard USB connector, so you just used any normal USB cable.As for a 20-pin header, I also have no idea what you are referring to. USB pin headers that I'm familiar with have always been 3 or 4 pin.

I am getting between 50-80MBps writes and slightly higher reads. Overall I am very happy with this card. My only complaint, if you can even call it that, is that the USB ports are not as tight as I like my ports to be. Not a big deal at all however and for the price, the performance is certainly right!

This card does not use any motherboard's USB resourses. So it will provide valid USB3 ports independently of motherboard's resourses, even in case m/b has no any build in USB at all.The only ultimate demand is PCI-x slot to plug the card in

I was not able to achieve full SATA 3 speeds with mine. I'm not sure what the reason is, but it is possible that other expansion cards on the system are using all available PCI-e lanes. YMMV

It works great on usb 2.0 - faster than a normal stick. But it reaches its full speed potential on a usb 3.0 port.

I have had three different models of USB 3.0 cards. They have worked in some cases and others not. Almost no way to tell from my experience. Sorry!!!

Mine, which is probably less than a year old has the USB 3.0 Micro-B port in back. It's been a really good card reader for me. The slots for the CF Card is *much* better and longer lasting than probably the last 3 crappy ones I've bought from other companies.

I can tell you I use the cable that came with it and have used it connected to USB 2 & USB 3 ports. It shows up as USB3 when connected there. I have never done any speed tests, but it has worked fine in all situations so far.
