NewerTech MAXPower 2x 2 USB/eSATA PCIe 2.0 Host Adapter for Mac OS X 10.8.3 and Later and Windows 7, 8, and Later

The power of USB 3.0 and 6G SATA high-speed interfaces are brought together on a single PCIe 2.0 card with the MAXPower eSATA/USB3 Host Bus Controller (HBA). This highly integrated I/O card saves valuable PCIe slots while adding the throughput desired for demanding applications such as video editing, audio mixing, and photography. The MAXPower eSATA/USB3 HBA provides two eSATA ports that are compatible with the latest 6G technology such as SSDs, as well as supporting legacy SATA devices, SATA hubs, and external optical drives. Simple to integrate and operate, it requires no drivers and supports hot-plugging, eliminating the need to restart the computer when connecting or disconnecting a SATA device. Since each USB and eSATA port commands a dedicated PCIe lane, card-level throughput of up to 2,000 MB/s can be achieved. Each of the two USB 3.0 ports can utilize the UAS protocol to transfer data to and from USB storage devices such as hard drives, solid state drives (SSDs) and thumb/flash drives for faster transfer speeds and lower CPU utilization than can be achieved with standard Bulk Only Transfer (BOT). Important Note: Apple OS X Sleep not recommended with this card. Sleep should be disabled when using devices with this card as you may otherwise experience volume ejections when waking from sleep. This issue is not present under Windows. NewerTech has reported a potential xHCI bug to Apple regarding sleep and we hope that Sleep support will exist in the future.
