* This term does not represent actual data rate of 480Mbps & 5Gbps and simply indicates compliance with USB 2.0 & USB 3.0 standards. Actual maximum data rate depends on computer configurations, cable conditions as well as connected devices. 

Power Usage Alerts :
- For stable operation, do not connect it to more than two high power-consuming devices, such as 1 TB hard drive.
- For Mac OS users, the devices on the PCI-E card will disconnect if the computer goes into **sleep.
- This USB 3.0 PCIe card is not meant to serve as a stand-alone charger.

**To minimize power usage during sleep, power is removed from PCIe cards. Because of this power-saving specification, the USB 3.0 PCIe card is unable to maintain USB port power during sleep. In OS X, this result in a storage device disconnect upon wake from sleep. The storage device will automatically remount, but the system reports a disconnect message. Because Mac OS X flushes all caches before sleeping, this disconnect should never result in any loss of data.

 *Actual performance may vary based on hardware, software, and overall system configuration.
