PEXUSB3S25
O Cartão PCI Express USB 3.2 Gen 1 de 2 Portas PEXUSB3S25 permite adicionar duas portas USB 3.2 Gen 1 ao seu sistema de computador habilitado para PCI Express, com um conector de energia LP4 opcional para se conectar à sua fonte de alimentação do sistema e fornecer até 900 mA de energia por porta para dispositivos alimentados pela USB 3.2 Gen 1 (500 mA para USB 2.0).
Aprimorado com suporte UASP (Protocolo SCSI Anexado por USB), este controlador USB 3.2 Gen 1 alcança até 70% mais velocidade do que o USB 3.2 Gen 1 convencional quando combinado com um (Nota: UASP não é suportado por todos os sistemas operacionais). Utilizando um protocolo mais eficiente do que o USB BOT tradicional (Transporte Apenas em Bloco), a tecnologia UASP otimiza as transferências permitindo que múltiplos comandos sejam processados simultaneamente, aumentando significativamente as velocidades de transferência e reduzindo o tempo de espera nas transferências de dados. Consulte abaixo os resultados dos nossos testes UASP para mais detalhes.
O adaptador PCIe USB 3.2 Gen 1 é compatível com os padrões USB 3.2 Gen 1 para velocidades de transferência de dados de até 5 Gbps, mantendo a compatibilidade com dispositivos USB 2.0 / 1.1 existentes. Para maior versatilidade, o cartão controlador está equipado com um suporte de perfil padrão e inclui um suporte de perfil baixo/meia-altura para instalação em computadores de pequeno formato.
Garantia StarTech.com de 2 anos e suporte técnico vitalício gratuito.
O UASP é suportado no Windows 8, 8.1, Server 2012 e no kernel do Linux 2.6.37 ou posterior. Nos testes, o UASP alcançou até 70% mais velocidade de leitura / 40% mais velocidade de escrita em relação ao USB 3.2 Gen 1 tradicional em desempenho máximo.
No mesmo pico nos testes, o UASP também mostrou uma redução de até 80% nos recursos do processador necessários.
Os resultados dos testes foram obtidos usando um sistema Intel Ivy Bridge, cartões USB 3.2 Gen 1 add-on da StarTech.com, um invólucro StarTech.com habilitado para UASP e uma unidade de estado sólido SATA III.
The PEXUSB3S25 2-Port PCI Express USB 3.0 Card lets you add two USB 3.0 ports to your PCI Express-enabled computer system, with an optional LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0).
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 is not supported by all operating systems). 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.
The PCIe USB 3.0 adapter is compliant with USB 3.0 standards for data transfer speeds up to 5 Gbps, while still offering backward compatibility with existing USB 2.0 / 1.1 devices. For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.
Backed by a StarTech.com 2-year warranty and free lifetime technical support.
Improved Performance with UASP
UASP is supported in Windows® 8, 8.1, Server 2012 and Linux kernel 2.6.37 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.
