PEXUSB3S42V
PEXUSB3S42V 4-Port PCI Express USB 3.2 Gen 1-kortet giver dig mulighed for at tilføje fire USB 3.2 Gen 1-porte med to dedikerede 5 Gbps-kanaler til din PCIe x4-aktiverede PC. Denne uafhængige portarkitektur forbedrer USB 3.2 Gen 1-ydeevnen ved at overføre data på to individuelle kanaler til din computer, hvilket giver dig hurtigere filoverførsler.
Når flere enheder er tilsluttet, deler traditionelle enkelbus USB 3.2 Gen 1-kort din maksimale båndbredde mellem alle porte. Ved at anvende en anden hostcontroller-chip reduceres transmissionskanalen for to porte i stedet for fire. At dedikere op til 5 Gbps til hvert sæt af to porte reducerer ydeevneflaskehalse og effektivt fordobler din samlede tilgængelige båndbredde til 10 Gbps.
Forbedret med UASP-understøttelse (USB Attached SCSI Protocol) udfører denne USB 3.2 Gen 1-controller op til 70% hurtigere end konventionel USB 3.2 Gen 1, når den er parret med en (Bemærk: UASP kræver et kompatibelt operativsystem). Ved at bruge et mere effektivt protokol end den traditionelle USB BOT (Bulk-Only Transport) optimerer UASP-teknologi overførsler ved at tillade, at flere kommandoer behandles samtidigt, hvilket markant øger overførselshastighederne for mindre ventetid på dataoverførsler. Se vores UASP-testresultater nedenfor for yderligere detaljer.
Til højstrøms USB-enheder inkluderer dette PCIe USB 3.2 Gen 1-kort en valgfri SATA- eller LP4-strømtilslutning for at tilslutte til din systems strømforsyning og levere op til 900mA strøm per port til USB 3.2 Gen 1 bus-drevne enheder (500mA for USB 2.0). USB 3.2 Gen 1-kortet understøtter også USB Battery Charging Specification 1.2 (kun Apple Mode), så du kan oplade kompatible Apple-enheder (iPhones og iPads) hurtigere end en standard USB 3.2 Gen 1-port.
Controllerkortet er i overensstemmelse med USB 3.2 Gen 1-standarder, mens det tilbyder bagudkompatibilitet med eksisterende USB 2.0 / 1.1-enheder. For øget alsidighed er USB 3.2 Gen 1 PCIe-kortet udstyret med en standardprofil-bracket og inkluderer en low-profile / half-height-bracket til installation i små formfaktorcomputere.
Understøttet af en 2-års garanti fra StarTech.com og gratis livslang teknisk support.
I test udførte UASP med op til 70% hurtigere læse / 40% hurtigere skrivehastighed over traditionel USB 3.2 Gen 1 ved maksimal ydeevne.
The PEXUSB3S42V 4-Port PCI Express USB 3.0 Card lets you add four USB 3.0 ports with two dedicated 5 Gbps channels to your PCIe x4-enabled PC. This independent port architecture improves USB 3.0 performance by transferring data on two individual channels to your computer, giving you faster file transfers.
When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports. By employing a second host controller chipset, the transmission channel is shared across two ports rather than four. Dedicating up to 5 Gbps for each set of two ports reduces performance bottlenecks, and effectively doubles your total available to bandwidth to 10 Gbps.
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.
For high-power USB devices, this PCIe USB 3.0 card includes an optional SATA or 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). The USB 3.0 card also supports USB Battery Charging Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones and iPads) faster than a standard USB 3.0 port.
The controller card is compliant with USB 3.0 standards while offering backward compatibility with existing USB 2.0 / 1.1 devices. For added versatility, the USB 3.0 PCIe 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
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.
