Enhanced Peripheral Performance
We know that shared bandwidth can limit performance. This adapter features two independent 5 Gbps channels. This means two ports share one channel. It effectively doubles the available bandwidth compared to single-channel cards. Your high-speed peripherals will operate more efficiently.
Faster Data Transfers with UASP
The card supports UASP (USB Attached SCSI Protocol). When paired with a UASP-enabled enclosure, transfers are significantly faster. This protocol processes multiple commands simultaneously. It reduces waiting times for large data transfers. This is ideal for external hard drives and SSDs.
Power for High-Demand Devices
Power delivery is crucial for many USB devices. This card includes an optional SATA or LP4 power connector. It supplies up to 900mA per port for USB 3.2 Gen 1 devices. USB 2.0 devices receive 500mA. We also include support for Apple Mode Battery Charging 1.2.
Flexible Installation Options
We understand diverse system requirements. This PCIe USB card comes with a standard profile bracket. A low-profile bracket is also included. This allows installation in both full-height and small form-factor PCs. It ensures broad compatibility.
