You can also connect older devices on the USB Type-C port using a variety of USB-C cables and adapters. -
Easy Installation
The USB 3.2 card is compatible with a broad range of Windows ; macOS and Linux operating systems. Plus, the high-quality card includes both standard-profile and low-profile brackets, making it easy to install in full or small form-factor PCs and servers. -
Faster Transfer Speeds with UASP
The card supports USB data transfer speeds of 10Gbps. But, you can experience transfer speeds up to 70% faster than conventional USB, when connected to a computer that also supports UASP. With UASP you can utilize the full potential of a SATA III SSD or HDD. UASP is supported in Windows 8, macOS (10.8 or above), and Linux . In testing, UASP performs with a 70% faster read speed and 40% faster write speed over traditional USB 3.2 Gen 2 at peak performance. At the same peak in testing, UASP also shows an 80% reduction in required processor resources. The PEXUSB311AC3 is backed by a StarTech.com 2-year warranty and free lifetime technical support.
