PEXUSB311AC3

这款USB 3.2 Gen 2卡片可让您通过PCI Express插槽向计算机添加一个USB-C端口和一个USB-A端口。它让您可以通过向计算机添加两个USB 3.2 Gen 2端口来升级您当前的系统，并可让您以每个端口高达10Gbps的数据传输速度访问数据。 USB 3.2 Gen 2（也称为USB 3.1）PCIe插件卡支持多个输入，即使连接了不同速度的设备，也能保持最佳带宽。

此外，通过向您的PC添加一个USB-C端口和一个USB-A端口，您可以轻松地连接传统、现代和未来的USB设备，无论USB连接器类型如何。

通过向您的计算机添加10Gbps USB端口，您可以利用USB 3.2 Gen 2的速度，并确保您已准备好应对当前和未来的高带宽USB-A和USB-C设备。

具有更高数据吞吐量支持的此USB 3.2 PCIe卡是外部驱动器、驱动器外壳和许多其他USB 3.2外围设备的必备品。此外，带有SATA电源的扩展卡可以为USB端口提供额外电源（当主板电源不足时），通过USB-C端口提供高达5V 3A/15W和通过USB-A端口提供5V 0.9A/4.5W的功率。该卡非常适用于高性能外部存储解决方案。

连接旧设备不是问题。这款功能齐全的双口USB 3.2卡向后兼容使用常见USB Type-A端口的旧USB 3.2 Gen 1/2.0设备，因此您可以消除购买新设备的额外费用和麻烦。您还可以使用各种USB-C电缆和适配器将旧设备连接到USB Type-C端口。

USB 3.2卡兼容各种Windows、macOS和Linux操作系统。此外，高质量的卡片包括标准配置和低配置支架，可轻松安装在全尺寸或小型形态的PC和服务器中。

该卡支持10Gbps的USB数据传输速度。但是，在连接到支持UASP的计算机时，您可以体验高达传统USB的70%更快的传输速度。通过UASP，您可以充分利用SATA III SSD或HDD的全部潜力。 Windows 8、macOS（10.8或更高版本）和Linux均支持UASP。

在测试中，UASP的读取速度快70%，写入速度快40%，超过了传统USB 3.2 Gen 2的最高性能。

在测试的最高峰值时，UASP还显示出80%的处理器资源减少。

PEXUSB311AC3由StarTech.com提供2年保修和免费终生技术支持。

This USB 3.2 Gen 2 card lets you add one USB-C™ port and one USB-A port to your computer, through a PCI Express slot. It enables you to upgrade your current system by adding two USB 3.2 Gen 2 ports to your computer and giving you access to data transfer speeds up to 10Gbps per port. USB 3.2 Gen 2 (also known as USB 3.1) PCIe Add-On card supports Multiple INs, maintains optimal bandwidth even when mixed speed devices are connected.

Plus, by adding one USB-C and one USB-A port to your PC, you can easily connect legacy, modern, and future USB devices, regardless of the USB connector type.

USB 3.2 Gen 2 Performance

By adding 10Gbps USB ports to your computer, you can harness the speed of USB 3.2 Gen 2 and rest assured you're ready for both current and future high-bandwidth USB-A and USB-C devices.

With higher data throughput support, this USB 3.2 PCIe card is a necessity for external drives, drive enclosures, and many other USB 3.2 peripherals. Plus, the expansion card with SATA power enables supplemental power to the USB ports (when motherboard power is insufficient) providing up to 5V 3A/15W via the USB-C port and 5V 0.9A/4.5W via the USB-A port. The card is ideal for use with high performance external storage solutions.

Compatible with Older USB Devices

Connecting older peripherals isn't a problem. This versatile dual-port USB 3.2 card is backward compatible with legacy USB 3.2 Gen 1/2.0 devices that use the common USB Type-A port, so you can eliminate the added expense and aggravation of purchasing new devices. You can also connect older devices on the USB Type-C™ port using a variety of USB-C cables and adapters.

Easy Installation

The USB 3.2 card is compatible with a broad range of Windows®; macOS and Linux® operating systems. Plus, the high-quality card includes both standard-profile and low-profile brackets, making it easy to install in full or small form-factor PCs and servers.

Faster Transfer Speeds with UASP

The card supports USB data transfer speeds of 10Gbps. But, you can experience transfer speeds up to 70% faster than conventional USB, when connected to a computer that also supports UASP. With UASP you can utilize the full potential of a SATA III SSD or HDD. UASP is supported in Windows® 8, macOS (10.8 or above), and Linux®.

In testing, UASP performs with a 70% faster read speed and 40% faster write speed over traditional USB 3.2 Gen 2 at peak performance.

At the same peak in testing, UASP also shows an 80% reduction in required processor resources.

The PEXUSB311AC3 is backed by a StarTech.com 2-year warranty and free lifetime technical support.
