PEXUSB3S42V

该PEXUSB3S42V 4端口PCI Express USB 3.2 Gen 1卡允许您向配备PCIe x4插槽的PC添加四个USB 3.2 Gen 1端口,其中包括两个专用的5 Gbps通道。这种独立端口架构通过在两个独立通道上传输数据到您的计算机来提高USB 3.2 Gen 1的性能,从而实现更快的文件传输。

当连接多个设备时,传统的单总线USB 3.2 Gen 1卡会在所有端口之间共享最大带宽。通过使用第二个主机控制器芯片组,传输通道跨两个端口共享,而不是四个端口。将每组两个端口专用于高达5 Gbps的带宽降低性能瓶颈,并有效地将总可用带宽提高到10 Gbps。

增强了UASP支持(USB Attached SCSI Protocol)的此USB 3.2 Gen 1控制器在与兼容操作系统配对时可比传统USB 3.2 Gen 1快70%。通过使用比传统USB BOT(仅限批量传输)更有效的协议,UASP技术通过允许同时处理多个命令来优化传输,显着增加数据传输速度,减少等待时间。有关更多详细信息,请查看下面的我们的UASP测试结果。

对于高功率USB设备,此PCIe USB 3.2 Gen 1卡包括一个可选的SATA或LP4电源连接器,可连接到您的系统电源,为USB 3.2 Gen 1总线供电设备提供每个端口高达900mA的功率(USB 2.0为500mA)。 USB 3.2 Gen 1卡还支持USB电池充电规范1.2(仅限苹果模式),可让您比标准USB 3.2 Gen 1端口更快地为兼容的苹果设备(iPhone和iPad)充电。

该控制卡符合USB 3.2 Gen 1标准,并向后兼容现有的USB 2.0 / 1.1设备。为增加多元化,USB 3.2 Gen 1 PCIe卡配备了一个标准配置支架,并包含一个用于在小型计算机中安装的低配置/半高度支架。

享有StarTech.com的2年保修,并提供免费终身技术支持。

在测试中,UASP在达到最大性能时的读取速度提高了70%,写入速度提高了40%,比传统USB 3.2 Gen 1快。
