AVS Gear USB 3.0 PCI Interface Card 2 ports Model UG-USB720202PCIE

Pros: Works great, the power connector allows me to run 2 external 2.5" hard drives on it at the same time. USB 3.0 is faster than USB 2.0.

Cons: none

Pros: Adds USB 3 to your computer. Fast - copied an 800 meg file in 8 seconds. Had to ding it an egg for the driver situation.

Cons: Poor packaging & web site. I noticed a few reviews complaining about the driver. While not obvious, there is a 3" cd included in the package. It's stuffed between the two glossy cardboard layers. I threw it away before digging it out! Also, have to agree that it's terrible that AVS Gear doesn't even list this model card on its web site.

Overall Review: If you've already thrown the disk away the card uses an NEC USB 3.0 chip. A quick google showed tons of drivers from dell and the like. They should do the trick.

Pros: Fast WHEN it works.... HDTune registered 125MB read/write on a Seagate FreeAgent 2TB external USB 3.0 drive... until it hits the 8192 kb block size, then read on...

Cons: This card, combined with the above mentioned Seagate FreeAgent 2TB USB 3.0 external, causes the drive to hang more often than not. Hangs at the 8192 kb block size on HDTune Pro. I've turned off USB power controls and suspension in the Power settings, and also tested the drive on a standard USB 2.0 port, and determined that this card is the culprit! I would send it back to Newegg get my money back, but I tossed out the original packaging. Wish I would've read the reviews regarding W7 64 issues prior to purchasing. AVS Gear isn't even a company anymore, and I'm not sure how much help it's current holder would be.

Overall Review: DON'T GET THIS CARD IF YOU ARE USING WINDOWS 7 64 BIT!!!

Pros: Works and very compact.

Cons: I would prefer that the 2 ports be farther apart for the occasional wider thumb drive.

Overall Review: The ports seam to have a very tight fit. I need to align the usb device perfectly and apply above normal pressure to connect a device.

Pros: Card works fine

Cons: none, excepts having genius like myself write bad reviews.... doh

Overall Review: Switching to the 1st PCI Express X1 lane made it work fine, most likely a motherboard or bios issue, should tried this before....

Pros: 2 fast usb 3.0 ports

Cons: drivers arent easy to find online didnt do a huge search online cuz i think i might know where i left the driver cd

Pros: At times it works, and when it does it works pretty ok! I got speeds upto 45MB/S over USB3 flash memory stick, but that could have been the USB flash memory limitation.

Cons: It gives me a lot of headaches on Windows 7 64 bit! It works sometimes, but most of the time it is like the drivers get unloaded and the system does not even find the USB 3 ports! Plugging in a harddrive does about as much as plugging it in a dummy USB slot! There is power over the USB slots though, making it not completely useless (you can still use it to charge your Ipod or something).

Overall Review: I've got a MSI Z68 motherboard, with Corei5 2500k and Win 7 64bit with 8GB RAM, and have connected the USB 3 interface to both a 1x and 4x slot, but had the same issue on both of them. I tried reloading the drivers without success. It's really the only item in my system that does not work the way it should! I'm not complaining about performance issues, I'm complaining about driver issues.

Pros: none so far, still troubleshooting. Going to try installing driver from website.

Cons: I'm trying to get this card working correctly with my ASUS P5G41T-M board, but when I plug in my wireless USB into the 3.0 port it eventually turns off all the USB ports that are connected to my motherboard. The power connector is plugged into the 3.0 adapter (also tried it without and got the same result). Still trying to see if it might just be my board. The bios was updated to the most current version.
