Experience: 2 Weeks

Good bang for the buck Verified OwnerVerified Owner


No low bracket adapter
bought it for oculus rift

Experience: 5 Days


Full USB 3.0
Needs SATA Power connector to it
It gives me enough USB 3.0 Ports for my USBs

Experience: 1 Days


Full USB 3 speed. Works perfect.
Must connect sata power connector to use it. Do not boot up windows without the power connector, bad stuff will happen. Driver disk did not work, and locked up my bluray drive.
Make sure to connect the sata power before using. update  firmware, and install latest drivers. If you do this, this card works perfect.
This card uses the D720202 chip, pick the firmware, update  it, and then install the 3.0.23 software driver, and you are golden.

Experience: 10 Days


Works as expected Read speeds tripled write speeds doubled tested with USB benchmark
nice upgrade on my old but still fast machine as i do a lot of file transfers

Experience: 2 Weeks


USB3 ports for my machines that don't have them, card is small, sata power connector to ensure it can deliver the full 900ma to both ports
Bought 2 for machines that don't have USB3 on the motherboard, and now that I have I'm not sure why I waited so long.

Experience: 1 Days


relatively cheap on sale ($14) uses a generic but well supported chipset compared to non-brand
received windows error upon first boot
Detected as a renesas usb 3 hub and worked straight out of the box. First boot on a 78LMTS2P motherboard without onboard usb3 produced a windows error. A quick reboot seem to have solved the issue and the additional usb ports were recognized (albeit not as usb3 ports). Installed the driver from the included CD and it was not recognized properly.

I would have preferred a standard molex on this card instead of sata power since this card was really short and the CM psu powering the system only had 2 sata cables. This meant that I had to dedicate an entire sata cord with 3 connectors just to reach the card - granted, this was on a system with a top-mount PSU. The molex peripheral cable were not being utilized on this particular system and this card would have made good use of it.

Anyway, it still worked without too much of an issue. There are versions of this card with an additional front header for front usb 3 or an all-rear accessible 4-port card.

Experience: 5 Months


Just works. No issues to be had. Powered from PSU.
Port shields (shrouds) stick out the back of the panel, making it hard to blindly insert  usb devices.
I was expecting it to need a Molex connector rather than the SATA power connector it does. That's my fault though. Seems rather generic, and it is, but it works. I don't get insane speeds on my i5 system, but it's better than 2.0 and I now have 2 more ports.

Experience: 14 Days


Cheap at 15$
None so far
Pleased with purchase so far , getting 113 MB/s reads and 101 MB/s writes on a ADATA Dash Drive Elite 64GB

Installed on two systems both working well.
Only drawback is lack of online drivers ie. dont lose the small cd you get in the package.
Or simply copy driver files to the cloud or HD

Experience: 3 Days


Good Pricing
Not compatible with old Motherboard BIOS Star P4M900-M4 - No screen display at POST (Power On Self Test)
Wide range on Driver Support - Windows XP, Windows 7 (32 and 64 Bit)and Windows 8 support.

No driver update  or firmware update  could be found on Mediasonic Website. Very week after market support on my previous product Portable Car Dash Video Recorder. I have reported a defective device Car Dash Recorder after 3 months usage and get no response from RMA Dept. besides the resolution is very poor on that. I hope this HP1-SU3 has a better quality and do not need to get to RMA.

Experience: 2 Months


Easy to install, functions as intended.
I wanted to add USB3 to my old Q6600 build, this did the trick and didn't break the bank!
