StarTech.com USB Port Cards Editorial Review
The StarTech.com 4-Port USB 3.0 PCI Express Card Adapter has garnered mixed reviews from users since its launch. Many customers found it easy to install on various Windows operating systems, including Windows 10 and Windows 7, and highlighted its compatibility with devices like the Samsung P3 external hard drive and the Oculus Rift. The performance of the card seems robust, with users appreciating that it supports two controllers, allowing efficient data transfer capabilities with five Gbps per two ports or a total of 10 Gbps when fully utilized. However, not all feedback is positive. Some users reported issues with the card ceasing to function after several months, leading to frustration, particularly for those relying on it for equipment like the Oculus Rift's room-scale setup. Others mentioned challenges in getting the card to operate properly on Windows 10, citing outdated drivers and a lack of support in virtualized environments. Furthermore, the necessity for specific PCIe slots—requiring a PCIe x4 or higher—has also posed limitations for installation in certain setups. In conclusion, this USB expansion card stands out for its ease of installation and good performance with multiple devices, but potential users should be cautious about its longevity and compatibility with newer systems or virtualized environments. **
