Anker - Uspeed USB 3.0 PCI-E Express Card with 4 USB 3.0 Ports and 5V 4-Pin Power Connector for Desktops [VL805 Chipset]

Installation went well on a Hewlett-Packard Windows 7 64-bit computer. I did have a bit of a scare when seating the card into the PCI-E slot. When the card seated, there was a snap sound. I think it was the silver metal of the card clanging against the body of the computer box. Not exactly a sound I want to hear but nothing broke and everything is working. Read on.The package contained:1) Anker Uspeed USB 3.0 PCI-E Express Card with 4 USB ports (with 5V 4-pin power connector)2) 5V 4-pin power connector to SATA power connector adapter cable3) USB 3.0 PCI-E Card Driver on mini-CD4) 2 screws (I didn’t need them)5) Instruction ManualInstallation steps are easy and are provided on the box as well as in the included Instruction Manual (which is more of a small four-page leaflet).This is what I did:1. I first connected the provided SATA to 4-pin adapter power cable to the Anker USB 3.0 card.2. With computer off and unplugged, I installed the Anker USB 3.0 card into the available PCI-Express slot and connected the power cable to an available SATA power connection in the computer. The available 5V- 4pin power connector in my computer was too short to reach the Anker USB 3.0 card but the provided SATA to 5V 4-pin cable adapter acted like an extension cord allowing me to connect the card. This was really helpful and I’m glad the adapter cable was included.3. Turned on the computer. The computer recognized the new hardware and attempted to install a driver but driver installation was unsuccessful.4. I put the mini-CD in the DVD drive and opened the disc to reveal one file: VIA_XHCI_Driver_V4.00B_NoAp.exe. I double clicked on the file and it installed the VIA XHCI Host Controller Driver v4.00B successfully5. Rebooted the computer to finish the installation.Note: The Instruction Manual states “Each USB port can only provide a 0.9A max. power current. For high-power devices, such as hard disks, please connect these to an additional power source to ensure sufficient power supply.”After reading this I was disappointed because I wanted to use a USB-only-powered portable USB 3.0 drive I have and not mess with an AC power cord. I decided to try it thinking what’s the worst that could happen? A system crash wouldn’t be the end of the world and I already imaged my System before installing the card. I’m happy to report everything worked well when using a USB-only-powered external hard drive.After the installation was complete I decided to see if I spent my money well. Here are some comparisons between the USB 2.0 port and my computer and using a USB 3.0 port in the newly installed Anker USB 3.0 card. I used the same ports on the computer for each data transfer and I used the same file for consistency. I listed each of the external hard drives I tried and put the time it took to transfer a large file below.Western Digital Elements External Desktop 2 TB 3.5” USB 2.0 AC-powered hard drive –USB 2.0 port: Time to transfer large file from Desktop to Drive was 3 minutes 5 secondsHGST Touro 2 TB 3.5” External Desktop USB 3.0 AC-powered hard drive -USB 2.0 port:Desktop to Drive: 2 minute 56 secondsDrive to Desktop: 2 minute 18 secondsAnker USB 3.0 card port:Desktop to Drive: 1 minute 45 secondsDrive to Desktop: 1 minute 2 secondsWestern Digital Elements SE Portable 1 TB 2.5” USB 3.0 USB-powered hard drive -USB 2.0 port:Desktop to Drive: 2 minute 48 secondsDrive to Desktop: 2 minute 18 secondsAnker USB 3.0 card port:Desktop to Drive: 1 minute 12 secondsDrive to Desktop: 1 minute 2 secondsI expected to see an improvement in data transfer time and I was not disappointed. The USB 3.0 connection greatly outperformed the USB 2.0 connection. I had no trouble with the USB-powered-only hard drive despite the notice in the Instruction Manual and the transfer time between the AC-powered and USB-powered external hard drives were similar. Interestingly, the Western Digital Elements SE portable drive significantly outperformed the HGST drive when transferring data from the Desktop to the Drive.If I have problems in the future I will post an update.

I purchased this card to give me a transfer speed boost when moving large files between my various Seagate and WD external hard drives. The card comes in a cute little black box with the driver CD, a SATA power to 4-prong MOLEX power extension cord, two screws, and two instruction guides. Based on the helpful reviews at Amazon, I also ordered a mod/smart Kobra SS Cable 4 pin MOLEX Extension - Carbon Fiber - 24 Inch for powering this card. The whole thing was installed in a few minutes into my Dell E521 running Windows XP SP3.I did some speed testing of my USB hard drives using a program called TeraCopy. I typically get about 20 MB/s of transfer speed on USB 2.0. With USB 3.0, I was getting just under 63 MB/s for definitely a solid improvement. I read in another review that someone was getting over 100 MB/s by using Amazon Basics USB 3.0 cables. I will definitely have to purchase a couple of those cables and test out the performance.I did encounter one irritating problem with the new card. I like to share my external hard drives on my home network and access them from my WD TV Live Streaming Media Player. I went through the normal procedure of setting up Windows Sharing for the hard drives, but I could not connect to them. When I tried to open the links that I had created via "My Network Places" > "View workgroup computers" > [my computer] > [each of my USB 3.0 hard drives], I kept getting this error:"\\[name of computer]\[name of drive shared] is not accessible. You might not have permission to use this network resource. Contact administrator of this server to find out if you have access permissions.Not enough server storage is available to process this command."I had never had an issue before with sharing my drives. I removed them from the USB 3.0 PCI-E Express Card and put them back on my USB 2.0 ports. They were recognized and could be shared without issue.After searching for a while, I found this Microsoft recommendation how to fix the problem. The solution is to:On the XP machine run Regedit, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters and make sure the value of IRPStackSize is set to decimal with a value of "15" (hex f). If the IRPStackSize parameter doesn't exist, create it as a DWORD value and set its value to decimal with a value of "15" (hex f).After manually making the recommended changes, I still could not network the drives on the USB 3.0 PCI-E Express Card. I did a bit more searching and found more people have similar issues. Many other people reported that they need to change the value to a different value instead of "15".Many people were reporting using values of the maximum value of "50", others reported that no values were working. Most people seemed to have success with a value of "30". I tried "30" and it worked. Now I can access the drives using the network share from the computer itself as well as my WD Media Player Live.I think this is a great card for the money ($19.99) and the responsiveness and higher transfer speeds are much better than USB 2.0.

The card gives a solid 2 or 3 times transfer rate over my USB 2.0 connections. I had no issues with it's installation.Win 7 Home x64, unplugged power, and carefully attached a molex to the card. Inserted it into a free x1 PCI-E slot, and powered up. Ran the driver install off the website for this card, and once completed, rebooted and tested it by connecting to a USB 3.0 portable hard drive (the hard drive does not have it's own power supply). All tested great. Rebooted with the drive attached and once into Windows, the drive was visible with no need to disconnect/reconnect.

I am not too savy on computer and when I bought the card, I tought it would fit in my computer.But when I received it , the plugs in my motherboard are not like the one on the card and I amleft with a card that is completely useless.So I do not like it , I hate it as the number of star is theclosest to how I feel. It is not the fault of Amazon or of Ankers, it is just that I did not know howto read that there are different types of plugs .Sorry Jeang

I bought this along with the phat Anker Uspeed usb 3.0 7 port hub.I have windows 7 home premium and had to use the mini cd to install drivers for the pcie card, which worked perfectly.Never had any disconnections or any other problems with this card.I cannot attest to the speed capabilities since everything I have is usb 2.0Would buy again.

Product is exactly as described. Works perfectly, great and simple driver support. Product shipped quickly and the price was reasonable. I`d have no issue buying again.

Positives:+ Driver installation was simple.+ Fair price (Paid CDN$ 23.99$) for overall good performances when compared to some other products in USB3.0 mode.+ Good packaging.Negatives:- Slower USB2.0 speed (20MBps) than other cards (30MBps).- Speed doesn't exceed 55MBps in USB3.0 mode which is far from USB3.0 potential.- Card wouldn't fit in the slot and had to apply force in order the get it to slide in properly.Performance:Getting a maximum of 55MBps Write & Read speed on USB3.0 and 20MBps in USB2.0 mode out of this USPEED (now ANKER) 68UPPCIE-4SU USB 3.0 PCI-E Express Card With 4 USB 3.0 Ports card.Compared to other products:Other products I tested with provided around 80MBps read and 50MBps write speeds with 30MBps in USB2.0 mode which is a better experience than the USPEED one overall. However I experienced with a lot of other USB3.0 cards which were easily double the price and and worst performance than this one.Other thoughts:This card was testing using the regular PCIE1X slot in which is was designed to work with - I could not install the card in 16x mode as the PC wouldn't boot - to it is possible that the card can work faster in 16X mode but I can't confirm as the PC on which it was used wouldn't boot when putting this card in a PCIE16x slot.Summary: If you want good USB3.0 read speed or USB2.0 performances stay away from this card. If 50MBps (double of USB2.0 or so) is sufficient for you then this card will do the job.
