Input: If your plan is to buy this card, attach it to a laptop, and then attach it to a GoFlex USB 3 Hard Drive, prepared to be disappointed.  This card does not provide enough power on its own to run USB hard drives.  Although it comes with a cord that allows for additional power to be provided to the card from a spare USB port on your laptop, something about the power output causes the drive to simply stop working after a while.  I initially thought it was my supplemental USB port turning off power, so I tried an external power source that I knew would not turn off and had the same result.  Tested the same drive using USB 2.0 directly, and no issues.<br /><br />This appears to be an OEM card that has multiple brands, and is based on the Renesas USB chip, so I suspect any of the cards that look exactly like this one and use the same driver will have the same result.  Works for probably 5-10 minutes, then stops.  Very disappointing.

Prepare to be disappointed.
