ECUSB3S22
ECUSB3S22 2-Port ExpressCard USB 3.2 Gen 1 Card 添加2个超速USB 3.2 Gen 1端口到一个ExpressCard-enabled计算机系统，使用34mm的形式因素，适配于34mm和54mm插槽，以及端口并排安装以便方便访问。
此USB 3.2 Gen 1控制器增强了UASP支持（USB Attached SCSI Protocol），当与支持UASP的外壳配对时，性能比传统USB 3.2 Gen 1高出70%（注意：UASP需要兼容的操作系统）。UASP技术比传统USB BOT（仅限批量传输）更高效，通过允许同时处理多个命令来优化传输，从而显著增加传输速度，减少数据传输等待时间。查看下面的UASP测试结果以获取更多详细信息。
USB 3.2 Gen 1支持高达5 Gbps的数据传输速率（比USB 2.0快10倍），并且能够为每个端口提供更多电力，以支持更快和更强大的设备。此外，这个ExpressCard适配器向后兼容USB 2.0/1.x，因此您所有现有的设备仍然可以使用。
由StarTech.com提供2年保修和免费终身技术支持。
具有UASP的改进性能
UASP受Windows® 8和Server 2012支持。在测试中，UASP在性能峰值处的读取速度比传统USB 3.2 Gen 1快70％，写入速度快40％。
在相同的性能峰值测试中，UASP还显示出对所需处理器资源高达80％的减少。
测试结果是使用Intel® Ivy Bridge系统，StarTech.com附加的USB 3.2 Gen 1卡，支持UASP的StarTech.com外壳，以及SATA III固态驱动器获得的。

The ECUSB3S22 2-Port ExpressCard USB 3.0 Card adds 2 SuperSpeed USB 3.0 ports to an ExpressCard-enabled computer system, using a 34mm form factor that will fit in both 34mm and 54mm slots, along with ports mounted side-by-side for easy access.
Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers. See our UASP test results below for further details.
USB 3.0 supports data transfer rates up to 5 Gbps (10x faster than USB 2.0) and is able to provide more power per port, to help support faster and more powerful devices. Also, this ExpressCard adapter is backward compatible with USB 2.0/1.x, so all of your existing devices will still work.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
Improved Performance with UASP
UASP is supported in Windows® 8, Server 2012 and Linux kernel 2.6.3 or later. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.
At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.
Test results were obtained using an Intel® Ivy Bridge system, StarTech.com add-on USB 3.0 cards, a UASP-enabled StarTech.com enclosure, and a SATA III solid state drive.
